Normal Operation
The vehicle security module controls the remote keyless entry (RKE) and power door locks. The vehicle security module receives power through the central junction box (CJB) fuse 107 (30A) and fuse 18 (10A). From these fuses power is delivered to the module through circuits 294 (WH/LB) and 7 (LG/YE), and is grounded on circuits 938 (BK/LG) and 57 (BK).

Possible Causes
- circuit 294 (WH/LB) open
- circuit 7 (LG/YE) open
- circuit 938 (BK/LG) open
- circuit 57 (BK) open
- vehicle security module
