The service BCM's EEPROM chip must be programmed with the proper RPO configurations. The EEPROM stores information regarding the vehicle options and point of sale. If the BCM is not properly configured with the correct RPO codes, the BCM will set default values for some systems, which could cause malfunctions in other systems. When the BCM is replaced, the BCM must be programed to identify the following information:

•	Real Time Damping (RTD)

•	Memory Options

•	Daytime Running Lamps (DRL)

•	Front Fog Lamps

•	Tire Pressure Monitor (TPM)

•	HVAC (C60-Manual, CJ2-Automatic)

•	Country of Sale (US, Canada, Europe, Japan, etc.)

The BCM sends a password to the PCM, therefore, the PCM must also be programmed to except the new password sent by the BCM. The BCM programming procedure will enable the learn password mode for both the BCM and PCM. This mode allows the PCM to learn the new password sent by the BCM whenever the BCM or PCM is replaced. If the BCM and PCM is not properly programmed together, the vehicle will exhibit a no start condition.

PASS-Key® Programming

When a BCM is replaced, the BCM must be programmed to accept the resistance value of the existing vehicle keys in order to allow PASS-Key® operation. When the BCM is replaced, the service replacement BCM is programmed to accept the first PASS-Key® resistance value detected. If the BCM is unable to detect a valid PASS-Key® resistance value, the BCM will never end the programming sequence and a DTC B2735 will set. The BCM can also be programmed to accept a new PASS-Key® code by completing the following BCM programming procedure

Step

Action

Value(s)

Yes

Using a Tech 2, select New BCM Setup and program the BCM with the correct RPO code configuration.

Is the BCM RPO configuration completed?

Go to Step 2

Important:

•	Before proceeding with this programming procedure, check for proper communications between the BCM and PCM. If communications cannot be established, refer to the appropriate Diagnostic System Check. for the system unable to communicate.

•	Maintain the battery voltage while the PCM and BCM is in the Learn Procedure. Follow this procedure exactly as indicated or you will have to repeat the procedure from the beginning.

•	Performing the following procedure causes a DTC P1630 to set when you complete the procedure. This is the intended functionality. When P1630 sets, turn OFF the ignition for 30 seconds, then turn ON the ignition and P1630 clears. If the DTC P1630 does not clear, go to the DTC P1630 table.

Turn ON the ignition leaving the engine OFF for 11 minutes.
Turn OFF the ignition for 30 seconds.
Turn ON the ignition leaving the engine OFF for 11 minutes.
Turn OFF the ignition for 30 seconds.
Turn ON the ignition leaving the engine OFF for 11 minutes or until DTC P1630 sets.
Turn OFF the ignition for 30 seconds.
Turn ON the ignition leaving the engine OFF and wait 30 seconds.
Attempt to start the engine.
