Test M: Remote Keyless Entry Transmitter Out Of Synchronization

M1 - M5:






Normal Operation
The keyless entry remote transmitters and the central security module use a rolling code to prevent the codes from being "captured" by a code grabber. The system advances the counter in the keyless entry remote transmitter and in the central security module every time a keyless entry remote transmitter button is pressed.

Possible Causes
^ DTC B2425 will set if the keyless entry remote transmitter is pressed a substantial amount of times while outside the range of the vehicle.
