If the security system will not arm from the remote transmitter, with all the doors properly closed, the following inputs to the SLCM should be checked:
Function
Passenger door ajar
Driver’s door ajar
Rear door ajar
Connector Identification
SLCM Connector CA 18-1
SLCM Connector CA 18-7
SLCM Connector CA 19-21

(Wire color codes: U=Blue, R=Red, W=White, N=Brown, O=Orange)
If any of the circuits are suspect, also check for entry of moisture into the rear door multiplug RD3.
TRANSMITTER TOTALLY INOPERATIVE
If the transmitter is totally inoperative, check whether the
LEDs on the transmitter illuminate when the “Lock” or
“Unlock” button is pressed.
If the LEDs do NOT illuminate, check the transmitter battery voltage levels. Each battery should be approximately 3 volts.
If the LEDs DO illuminate, check that the transmitter and security system have not lost their code synchronization.
The system is designed with a rolling code window of
100 activations of the transmitter. This means that if the transmitter is operated 100 times out of range of the vehicle to which it is coded, it will lose synchronization with the vehicle. If this occurs, repeated operations of the transmitter will not unlock the vehicle.
In this case, the security system may be disarmed by unlocking the doors using the vehicle key.
Once the vehicle is in an unlocked and disarmed state, the RF transmitter(s) will re-synchronize to the vehicle after 3 activations within signal range.
have lost code synchronization, and the transmitter button is pressed while the vehicle is locked and armed, the SLCM may enter the “Anti-scan” mode. This will inhibit any transmitter operation for approximately 2 minutes.
