Test Q
PINPOINT TEST Q: THE REMOTE TRANSMITTER IS OUT OF SYNCHRONIZATIONTest Q1-Q4:
Normal Operation
The remote transmitters and the driver door module (DDM) use a rolling code to prevent the codes from being "captured" by a code grabber. The system advances the counter in the remote transmitter and in the DDM every time a remote transmitter button is pressed.
All remote transmitters must be present to begin diagnosis of the remote keyless entry (RKE) system.
Possible Causes
- DDM DTC B2425 RKE out of synch
- aftermarket systems
- high power devices
- TV/radio transmission towers
- remote transmitter
- DDM
- remote transmitter button pressed a substantial amount of times while outside the range of the vehicle
