Body Control Module: Other GMC Envoy I

TBC MODULE PROGRAMMING/RPO CONFIGURATION

Note. Use of Tech 2 scan tool is recommended for programming TBC module. A generic scan tool may not be capable of performing all necessary programming functions. Refer to scan tool manufacturer's instructions.

Programming Procedure

1. Ensure battery is fully charged. Turn ignition switch to RUN position. Program TBC module using scan tool. Refer to Techline(R) terminal and equipment user's instructions.
2. If TBC module fails to program, check all connections. Ensure latest software version for scan tool is used. Retry programming TBC module. If programming fails again, replace TBC module.

TBC/BCM RELEARN PROCEDURE

Note. A scan tool can be used to perform relearn procedure. Refer to scan tool manufacturer's instructions. Procedure will take about 10 minutes with use of scan tool.

Relearn procedure should be performed if any of the following components are replaced, PassLock(R) sensor, TBC Module, PCM or VCM. Performing relearn procedure without the use of a scan tool will take about 30 minutes.

Relearn Procedures

1. Turn ignition off. Replace failed/affected component.
2. Turn ignition switch to RUN position, then to CRANK position (without starting engine), then back to RUN position.
3. Observe SECURITY indicator light on dash for 10 minutes. After 10 minutes, indicator light will turn on, then off.
4. Repeat steps 2) and 3) twice. After successfully completing 3 consecutive cycles of ignition switch, vehicle will learn the new component on the next ignition cycle, which is from OFF to CRANK then to RUN position. Engine should start.
5. After performing relearn procedures, clear DTCs. See «CLEARING DTCS»(ref-33327-S08500004602001101600000) under SELF-DIAGNOSTIC SYSTEM.

CLEARING DTCS

Note. Disconnecting battery cables or TBC module harness connectors will NOT clear history DTC(s).

If conditions for malfunction no longer exist, history DTC will clear after 100 consecutive ignition cycles or by using scan tool to clear DTCs.

TRUCK BODY CONTROL (TBC) MODULE

Note. Ensure ignition is off when disconnecting TBC module harness connector. ALWAYS disconnect Brown TBC module connector first and reconnect it last to avoid setting DTC.
