Component Tests and General Diagnostics

1. CHECK condition of PWR ACCY Circuit Breaker. If the Circuit Breaker is open, LOCATE and REPAIR cause of overload and RESET Circuit Breaker.
2. CHECK that Grounds G200 (Upfitter Provisions only), G201, and G402 are clean and tight.
3. Following locking of all doors, if the Side Door locks immediately after closing, then REPLACE the Power Door Lock Control Module.
4. Following locking of all doors, if the Side Door locks with the Side Door open, then REPLACE the Power Door Lock Control Module.
5. The transmitter should work within approximately 7 meters (23 feet) of the vehicle in perfect conditions. Transmitter location in respect to the vehicle and interference with other objects or with other radio signals may reduce the effective range. CHECK condition of Remote Control Door Lock transmitter battery. REPLACE as required.
6. Refer to Interior Lights for operation of the Interior Lighting System from the Remote Control Door Lock Receiver. Lighting and Horns
7. See instructions for programming the Remote Control Door Lock Receiver for different transmitters.
8. After checking power and ground to the Remote Control Door Lock Receiver, refer to transmitter problems diagnosis.
9. If both the Side and Rear Door Lock Actuator Motors are inoperative (Base only, not Upfitter Provisions), then LOCATE and REPAIR the open in the GRY (295) wire between Splice S244 and Splice S315.
^ CHECK for a broken (or partially broken) wire inside the insulation which could cause system malfunction but prove "GOOD" in a Continuity/Voltage check with a system disconnected. These Circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a Voltage drop with the system operational (under load).
^ CHECK for proper installation of aftermarket electronic equipment which may affect the integrity of other system (Refer to "General Troubleshooting Procedures,"). Diagnostic Aids
