Pinpoint Test A: The Alarm System Does Not Arm/Disarm - Using The Integrated Keyhead Transmitter (IKT) Key

Normal Operation

The Smart Junction Box (SJB) receives lock/unlock commands from the Remote Keyless Entry (RKE) transmitter (part of the Integrated Keyhead Transmitter (IKT) key). The SJB then arms/disarms the perimeter alarm system.

This pinpoint test is intended to diagnose the following:

- IKT key concern
- SJB

PINPOINT TEST A: THE ALARM SYSTEM DOES NOT ARM/DISARM - USING THE IKT KEY

NOTE: All IKT keys must be present before diagnosing the RKE system.

-------------------------------------------------
A1 CHECK THE LOCK FUNCTION USING THE IKT KEY


- Press the LOCK and UNLOCK buttons on the IKT key.
- Do the doors lock and unlock using the IKT key?

Yes
GO to A2.

No
REFER to Handles, Locks, Latches and Entry Systems Testing and Inspection.

-------------------------------------------------
A2 CHECK FOR CORRECT SJB OPERATION


- Disconnect all the SJB connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the SJB connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new SJB. REFER to Multifunction Electronic Modules Service and Repair. CYCLE each key to the ON position for a minimum of 6 seconds to PROGRAM the RKE function of the IKT keys. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
