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.
^ 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
