Pinpoint Test 5: Remote Keyless Entry (RKE) Transmitter Is Out of Synchronization
PINPOINT TEST 5: REMOTE KEYLESS ENTRY (RKE) TRANSMITTER IS OUT OF SYNCHRONIZATIONStep 1-Step 4:
Normal Operation
The remote keyless entry (RKE) transmitters and the smart junction box (SJB) use a rolling code to prevent the codes from being "captured" by a code grabber. The system advances the counter in the RKE transmitter and in the SJB every time an RKE transmitter button is pressed.
DTC B2425 - sets when the SJB senses that the key fobs are out of synchronization.
Possible Causes
- RKE transmitter button pressed a substantial amount of times while outside the range of the vehicle
- RKE transmitter
- SJB
NOTE: All RKE transmitters must be present to begin diagnosis of the RKE system.
