Test C9-C10:
Normal Operation
Remote locking and unlocking of the doors is accomplished by the vehicle security module receiving a command message from the remote transmitter. The vehicle security module processes the command and sends a signal directly to the door lock actuators.
All remote transmitters must be present to begin diagnosis of the remote keyless entry (RKE) system.
Aftermarket or dealer-installed systems may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.
Possible Causes
- remote transmitter battery
- remote transmitter programming
- remote transmitter
- aftermarket systems
- high power devices
- TV/radio transmission towers
- vehicle security module
