-------------------------------------------------------------------------------- --Identifing OBD-I equipped cars Sold in the United States between ??? and
January 1, 1996 were required to be OBD I equipped. --OPERATING ON-BOARD DIAGNOSTIC SYSTEM To enter diagnostic mode: Turn
ignition "ON." Depress the "OFF" and "WARMER" buttons on the Climate Control Center (CCC) simultaneously and hold until the segment
check appears on the Instrument Panel Cluster (IPC). --TROUBLE CODE DISPLAY After entering On-Board Diagnostics, a segment check
is automatically performed and then any trouble code stored in computer memory will be displayed. Codes may be stored for the
Powertrain Control Module (PCM), Instrument Panel Cluster (IPC), Air Conditioning Programer (ACP), Supplemental Inflatable Restraint
(SIR) Traction Control System (TCS) or Road Sensing Suspension (RSS) systems. Each trouble code consists of the system abbreviation:
(E: Engine, PCM), (I: IPC), (A: ACP), (R: SIR), (T: TCS), (S: RSS), a three digit code identifier, and the letter C or H. All codes for each
system are displayed together, in the order of their three digit number (lowest first). The final digit of the code, a "C" or "H" is used to
indicate whether the code is Current or History. A "C" means the fault was still present the last time the diagnostic test was run, while "H"
means the failure was not present the last time the code was tested for. If no codes are present for a system, a "NO X CODE" message
(with "X" being the system i.e. E, I, A, R, T or S) will be displayed. If the communication line to a component is not operating, a "NO X
DATA" message will be displayed, indicating that the IPC could not communicate with that system. --SELECTING THE SYSTEM After
trouble codes have been displayed, a specific vehicle system PCM, IPC, ACP, SIR, TCS, RSS may be selected for testing. The first
available system will be automatically displayed (i.e. PCM?). While selecting the system to test, any of the following actions may be taken:
Depressing the "HI" button on the CCC will select the displayed system for testing. Depressing the "LO" button on the CCC will display the
next available system selection. This allows the display to be stepped through all system choices. This list of systems can be repeated
following the end of the system list. Depressing the "OFF" button the CCC will stop the system selection process and return the display to
the beginning of the trouble code sequence. --SELECTING THE TEST TYPE Having selected a system, the first available test type will be
displayed (i.e. PCM DATA?, PCM CLEAR CODES?). While selecting a specific test type, any of the following actions may be taken:
Depressing the "HI" button on the CCC will select the displayed test type. At this point the first of several specific tests will appear.
Depressing the "LO" button on the CCC will display the next available test type for the selected system. This allows the display to be
stepped through all available test type choices. This list of test types can be repeated following the display of the last test type. Depressing
the "OFF" button on the CCC will stop the test type selection process and return the display to the next available system selection. --CLEAR
CODES Selection of "CLEAR CODES?" test will result in the message "CODES CLEARED" being displayed along with the selected
systems name. This message will appear for 3 seconds and then return to the next available test type. --EXITING DIAGNOSTIC MODE To
get out of the diagnostic mode anytime during the test, depress the "AUTO" or "DEFOG" button, or turn the ignition switch "OFF." Trouble
codes are not erased if this is done prior to selecting "CODES CLEARED." --Customer Snapshot DESCRIPTION The Northstar
powertrain has an unique feature that allows a Powertrain Control Module (PCM) snapshot to be recorded without being in on-board
diagnostics by simply pressing two buttons on the Climate Control Center (CCC). This feature, called Customer Snapshot, records a
complete set of PCM data parameters and inputs when the "OFF" and "FRONT DEFROST" buttons on the CCC are pressed
simultaneously. Customer Snapshot only works when the vehicle is NOT in on-board diagnostics. This feature can be very useful when it is
difficult to reproduce a condition. When this occurs, the owner or driver may be instructed to take a Customer Snapshot while the condition
is present and return to the dealer for diagnosis when convenient. ACTIVATING SNAPSHOT A Customer Snapshot may be taken anytime
the ignition is on and the vehicle is not in on-board diagnostics. While this is true, pressing the "OFF" and "FRONT DEFROST" buttons
simultaneously for one second will cause a snapshot to be taken and the "Service Engine Soon" Malfunction Indicator Lamp (MIL) to be
turned "ON" for 2 seconds as confirmation that a snapshot was taken. RETRIEVING SNAPSHOT DATA This data may be retrieved by
entering diagnostics, selecting PCM SNAPSHOT and viewing the P001 SNAPSHOT (It will appear as a code snapshot with and code
designation of P001, hence the P001 SNAPSHOT designation.). The Customer Snapshot data will be overwritten if another Customer
Snapshot is taken or if a PCM snapshot is taken while in on-board diagnostics. --GM Diagnostic Trouble Code List Instrument Panel

Reading the Cadillac Onboard Diagnostic Codes
If you have a problem, why not ask the Cadillac what's wrong?
One wonderful feature of most Cadillacs, including the Deville / DTS, the Seville / STS, and the Catera / CTS up to 2003, and the Allante, is the
availability of onboard diagnostics.
By pressing a set key sequence on the dash, the Cadillac will display any trouble codes, warnings, or watch conditions being monitored by any of the
various control systems. These trouble codes are called Diagnostic Trouble Codes (DTC), and are shown by system.
You can reset the codes using the onboard diagnostics, and in some cases make changes to the way that the vehicle operates. This article addresses
the basics of how to get in to the system, back out of the system, and use some of the info found there. Please see the How-To section for more
information.
DTC display; 1998-2004 Seville and 2000-2005 Deville
by JimD
Use the 3 switches located to the right of the Driver Information Center (DIC) to activate and respond to the OBD prompts on the DIC.
ON/OFF = YES
INFO RESET = NO
INFO DOWN or INFO UP = manual toggle
Ignition ON, acknowledge any warning messages; press ON/OFF and INFO UP together for 2 to 3 seconds. Everything in front of you lights up for 4 or
5 seconds, then you will see:
Display shows "ALL?"
Answering YES will display "ALL CODES?"
Answering YES will run automatic test sequence and display codes, if any. Systems and codes will scroll faster than I am able to read them and write
them; not to worry.
"ALL CLEAR CODES?" will display at the end of the automatic test. If you are satisfied you have the information you need, answer YES to clear/erase
all error codes.
Answering "ALL?" with INFO DOWN will toggle systems test manually in order.
Answering "ALL?" with INFO UP will toggle system test manually in reverse order.
Press INFO RESET to reset DIC to "ALL?" to start again.
Ignition OFF to exit.
SYSTEMS: (as of 1998)
ABS (Antilock Brake System)
AMP (Amplifier)
DDM (Door Driver Module)
DIM (Dash Integration Module)
IPC (Instrument Panel Cluster)
IPM (Instrument Panel Module)
IRC (Integrated Radio Module)
PCM (Powertrain Control Module)
RFA (Remote Function Actuation)
RIM (Rear Integration Module)
SDM (Sensing and Diagnostic Module) Includes airbag crash data. Under RF seat of Seville.
VTD (Vehicle Theft Deterrent)
MSM (Memory Seat Module)
TTM (Tilt/Telescoping Module)
RSS (Road Sensing Suspension)
DTC display 1989-2000:
1. Turn the ignition switch ON. [Bruce notes: interestingly, the engine can be on or off]
2. On the cars up to 1995, on the Climate Control panel, press the OFF and WARM buttons simultaneously.
On the 96/97, push the OFF button and the top (warmer) end of the PASS rocker switch.
For 99 Deville, Turn the ignition switch to ON. Simultaneously press the following buttons until all VF display segments (IPC and CCP) are illuminated:
The digital IPC, the climate control center (CCC) OFF and warmer (RED) buttons
The analog IPC, the climate control panel (CCP) OFF and PASS warmer (up arrow) buttons
On the 98-2000, there seems to be some discussion:
GM ESI CD version:
1) Turn the ignition on, engine off. 2) Press the RESET button to acknowledge any warning messages present 3) Press the OPTIONS button on the
driver information center and hold 4) While pressing the OPTIONS button, press the FUEL button 4 times within a 10 second
period. System will first enter automatic display mode followed by manual display mode.
Willy Spenser writes how to really do it for the 98+:
With the ignition key on, running or not makes no difference, press the on/off and info^(info/up) buttons for the DIC at the same time for about 2-3
seconds and release. It should then be itn the DTC check mode. Use the on/off button to select,when it
lists a question,i.e CODES?...,press on/off button to select that. The codes for each system will now appear if there are any. Otherwise it will say NO
RSS, NO PCM,ETC... Use the reset info button to return or go back to the previous selection. When it asks you CLEAR CODES?...press the on/off
button to clear them IF YOU WANT THEM CLEARED, if no, press reset info repeatedly until you exit. You can also exit by turning the ignition switch off.
This should work on '98 and up Sevilles.
3. Hold the buttons depressed until all display segments on the CC/DIC and instrument Panel Cluster (IPC) illuminate. On 1992 models, a separate
combination panel houses both the ECC and DIC. On 1993-1994 models, the DIC is part of the instrument panel cluster.
4. After the segment check, the diagnostic trouble codes will be displayed. Each trouble code consists of the system identifier, a three-digit code
identifier and the current or history identifier. If no codes are present for a system, a NO X CODE or NO X DATA message will be displayed.
E -- ECM trouble code
P -- PCM trouble code
C -- Current trouble code
H -- History trouble code
NO X CODE -- No code present (X represents the system)
NO X DATA -- Communication lines are not operating (X represents the system)
SEGMENT CHECK
The segment check is the illumination of the IPC, CCP, and DIC to verify that all segments of the liquid crystal displays [The display is actually
florescent, not liquid crystal, but the GM text says LCD] are working. Only the turn signal indicators do not light during this check. Diagnosis should not
be attempted unless all segments appear, as this could lead to misdiagnosis. If any portions or segments are inoperative, the faulty component should
be replaced.
STATUS LIGHTS
When the system is placed into the Diagnostic Mode, the lighting elements on the climate control panel are used as status lights for various
components. The mode of operation is determined by the light being ON or OFF. The use of each lighting element is different in ECM or BCM mode.
For example, in the ECM mode the word OFF on the CCP will light to indicate a rich condition sensed by the left oxygen sensor input. In BCM mode, the
same light is ON when the BCM commands the air inlet valve to the recirculate position.
TROUBLE CODE DISPLAY
After diagnostics is entered, any fault codes stored in computer memory will be displayed. For 1992 systems, codes may be stored or the ECM, BCM or
SIR systems. For 1993-1994 the system has been expanded to include codes for the PCM, IPC, ACP, SIR, TCS, and RTD systems The Instrument
Panel Cluster (IPC) replaces the BCM for 1993-1994 models, but serves the same purpose. ACP, SIR, TCS, and RTD stand for Air Conditioning
Programmer, Supplemental Inflatable Restraint, Traction Control System, and Real Time Dampening, respectively. We will only deal with Engine control
malfunctions here.
Each trouble code consists of the system identifier (E for ECM or P for PCM), a three-digit code identifier and the letter C or H to indicate current or
history codes. If no codes are present for a system, a NO X CODE message will be displayed, with X representing the system.
On 1992 models, the RESET/RECALL button on the DIC will terminate diagnostics and return the vehicle to normal operation. For 1993+, depress the
AUTO button on the ECC panel to return to normal operation.
