BCM Identification
This vehicle is equipped with 1 of 3 types of BCMs. The BCM type installed on this vehicle is based on the vehicle equipment, point of sale, and option content.
Refer to On-Board Diagnostic Features for more information on how to identify the BCM type installed by using the on-board diagnostic feature. The following identifies the functions and basic option content of all 3 BCM types:
BCM Type 2
BCM type 2 is the base BCM that provides all standard BCM functions. Refer to the BCM function table for type 2 BCM.
BCM Type 3
BCM type 3 provides all of the features of the BCM type 2 plus keyless entry. Vehicles with RPO AU0 are equipped with a BCM type 3.
BCM Type 4
BCM type 4 provides all of the features of the BCM type 2 and type 3 plus content theft deterrent. Vehicles with RPO AU0 and UA6 are equipped with a BCM type 4.

On-Board Diagnostic Features
This vehicle is equipped with an on-board diagnostic feature capable of performing the following functions:
• Feature Customizing
• Displaying DTC codes
• Clearing DTC codes
• Input/Output Diagnostics
Feature Customizing Mode
The feature customizing mode is used to configure the BCM to function in various applications. The BCM can be customized to change the following vehicle functions:
• Interior Lighting Features
• Door Lock System
• Keyless Entry System
• Content Theft Deterrent System
In order to enter the feature customizing mode perform the following steps:
Turn the ignition switch to the LOCK position.
Remove the BCM PRGRM fuse.
Turn the ignition switch to the ACC position.
When entering the feature customizing mode, the BCM first identifies what type of BCM is installed on the vehicle by flashing the fasten seat belts indicator and sounds the chime 2, 3 or 4 times depending on the type of BCM used on the vehicle. There are 3 different types of BCM that can be installed on the vehicle based on the vehicle option content that matches the BCM capabilities. Ensure that the BCM installed on the vehicle is compatible with all of the features on the vehicle. Refer to Body Control System Description and Operation for BCM identification.
For more information on features that can be customized, refer to Personalization Description and Operation in Personalization.
Displaying DTC Codes
The DTC codes can be displayed by entering the diagnostics mode. Clearing DTC codes and Input/Output Diagnostics are also available in the diagnostics mode.
Complete the following steps in order to enter the diagnostics mode:
Turn the ignition switch to the LOCK position.
Remove the BCM PRGRM fuse.
Turn the ignition switch to the ACC position.
Quickly turn the ignition switch from the ACC position to the LOCK position then back to the ACC position within 1 second.
The BCM will enter the on-board diagnostic mode and flash the fasten seat belts indicator and sound the chime equal to the number of DTCs stored in the BCM memory. If no DTCs are stored, the BCM will not flash the fasten seat belts indicator or activate the chime.
The BCM flashes and sounds the first DTC with the lowest number, pauses, then continues with the next DTC until all of the DTCs are read. With a DTC 1, the BCM will only sound the chime once, and the fasten seat belts indicator may not flash. Once all of the DTCs are read, the BCM repeats this sequence 3 times.
Important: If the fasten seat belts indicator does not flash, and the chime does not sound, complete the following procedure in order to confirm that the BCM has entered the diagnostics mode:
Ensure that all of the vehicle doors are closed.
Open and close any vehicle door.
Fasten and release the driver seat belt.
The BCM sounds the chime when receiving an input signal such as Drivers door, Passengers door opening or turning on the courtesy lights when the BCM is in the diagnostics mode. Make sure these inputs are working correctly in order to prevent a false diagnoses.
If the BCM does not sound the chime upon opening a door or turning on the courtesy lights, repeat Step 1 of Entering the diagnostics mode. If the BCM does not enter the diagnostics mode, then refer to Cannot Enter BCM Diagnostics .
Clearing DTC Codes
After entering the diagnostics mode press and hold the Unlock switch for 4 seconds. The BCM will erase all history DTC codes. If a circuit is still shorted, the BCM will immediately store a history DTC code.
Input/Output Diagnostic Mode
After the BCM reads all of the DTCs in the memory, the BCM enters the Input/Output Diagnostic Mode.
The BCM flashes the fasten seat belts indicator and sounds the chime once when any of the following inputs are activated:
• Courtesy lamp switches
• Door lock cylinder switches
• Driver door ajar switch
• Headlamp switch
• IP compartment lamp switch
• Keyless entry request for door lock/unlock
• Keyless entry request for the alarm (RPO UA6)
• Passenger door ajar switch
• Power door lock switches
• Liftgate ajar switch

2000-2004

The Diagnostic Mode is entered by turning the ignition from OFF to ON while holding the reset switch in. The normal power-up sequence will occur before entering the diagnostic mode. Diagnostic codes set during this power-up sequence will be stored as well.

Important Note: Be sure no diagnostic codes are indicated before reset is held in for more than 5 seconds or diagnostic information will be lost.

When in diagnostic mode the odometer will display the first diagnostic code. When the trip switch is pressed again the next code will be shown. If the trip switch is pressed for more than 5 seconds at any time while in the diagnostic mode, the diagnostic code displayed will be erased.

There are 7 different diagnostic codes available. They are as follows:
d01 - Speed sensor power output shorted low
d02 - Speed sensor power output shorted high or open
d03 - Not Used
d04 - Not Used
d05 - Speed sensor return shorted high
d06 - Speed sensor return shorted low
d07 - Not Used
d08 - Speedometer power over voltage
d09 - Speed output shorted high
d10 - Speed output shorted low or open
CAL XX - Speedometer application calibration number:
14 = Domestic
15 = HDI


When in the diagnostic mode, all codes are displayed in sequence from d01 to d10.

As a code appears in the display (for instance d02), it will read "d02Set" if set or "d02CLr" if clear.

The diagnostic mode is exited either by turning ignition from ON to OFF to ON again without depressing the reset switch or if a speed signal greater than 5 MPH is detected.

Diagnostics cannot be performed if system voltage is less than 9 VDC or greater than 16 VDC. The only exception is d08 which is set when system voltage is greater than 16 VDC.

After all the diagnostic codes are displayed, the speedometer calibration number is displayed (CAL 14 for example).
