Keyless Entry: Testing and Inspection

On models without the Remote Keyless Entry (RKE) option, diagnosis should begin with the door modules. (Refer to POWER LOCKS/DOOR MODULE - DIAGNOSIS AND TESTING - POWER LOCK CONTROL). As a preliminary diagnosis for models with the RKE system, note the power lock system and illuminated entry system operation while you actuate both the Lock and Unlock functions with the power lock switches and the RKE transmitter. Then proceed as the following results indicate:
- If the entire power lock system fails to function with either the power lock switches or the RKE transmitter, disconnect the wire harness connector from the RKE module and test the power lock system operation again using the power lock switches. If the power lock system now operates, diagnosis should begin with the Remote Keyless Entry Module. (Refer to POWER LOCKS/REMOTE KEY- LESS ENTRY MODULE - DIAGNOSIS AND TESTING). If the power lock system still fails to operate, diagnosis should begin with the door modules. (Refer to POWER LOCKS/DOOR MODULE - DIAGNOSIS AND TESTING - POWER LOCK CONTROL).
- If the power lock system functions with both power lock switches, but not with the RKE transmitter, diagnosis should begin with the RKE transmitter. (Refer to POWER LOCKS/KEY LESS ENTRY TRANSMITTER - DIAGNOSIS AND TESTING).
- If one power lock motor fails to operate with both of the power lock switches and/or the RKE transmitter, diagnosis should begin with the power lock motor. (Refer to POWER LOCKS/DOOR LOCK MOTOR - DIAGNOSIS AND TESTING).
- If the RKE and power lock systems are functioning, but the illuminated entry system fails to operate, diagnosis should begin with the RKE module. (Refer to ELECTRICAL POWER LOCKS/REMOTE KEYLESS ENTRY MODULE - DIAGNOSIS AND TESTING).
