Body Control Module Programming/Regular Production Option Configuration
NOTE:
When Body Control Module (BCM) is replaced, new BCM will automatically program to resistance of ignition key setting that is used first time ignition switch is turned to RUN position. This process can only be performed once for life of BCM. BCM can only be programmed to one ignition key resistance. All ignition key resistances must match.
NOTE:
After BCM is replaced, feature customization for personalized settings will automatically resort to default settings. Feature customization settings should be programmed as needed. See ENTER FEATURE CUSTOMIZATION MODE
.
- After a replacement BCM has been installed, use one of customer's keys to turn ignition switch to RUN position, with engine off. Observe SECURITY indicator and start engine to verify system operation. If SECURITY indicator comes on for about 5 seconds and then goes out, BCM is programmed properly, go to next step. If SECURITY indicator flashes (about one flash per second) until ignition switch is turned to LOCK position, BCM did not program. Diagnose anti-theft system fault. See THEFT DETERRENT DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM.
- After programming BCM, perform the following to avoid future misdiagnosis:
- Turn ignition switch to LOCK position for 10 seconds.
- Connect scan tool to Data Link Connector (DLC). DLC is located below steering column, on bottom of knee bolster. See Figure .
- Turn ignition switch to RUN position, with engine off.
- Using scan tool, retrieve history DTCs from all modules.
- Clear all history DTCs.
