Anti-Theft - Perimeter

PINPOINT TEST A: THE ALARM SYSTEM DOES NOT OPERATE CORRECTLY

Normal Operation
The smart junction box (SJB) arms the alarm (after 20 seconds have elapsed) when a lock signal is received from the remote keyless entry (RKE) transmitter (part of the integrated keyhead transmitter [IKT] key), the keyless entry keypad, or the door lock control switch (with the door open, then closed). The SJB disarms the alarm when an unlock signal is received from the RKE transmitter, the keyless entry keypad, the door disarm switch or if the ignition key is turned to the ON position.

With the anti-theft perimeter alarm system armed, the SJB monitors the door ajar switches on circuits CPL26 (GN/VT) (LH front door), CPL31 (WH) (RH front door), CPL36 (GN) (LH rear door), and CPL39 (YE) (RH rear door). When an unauthorized intrusion to the passenger compartment occurs, the applicable door ajar switch completes the circuit to ground through circuits GD133 (BK) (LH front door), GD148 (BK/YE) (RH front door), GD147 (BK/VT) (LH rear door), and GD148 (BK/YE) (RH rear door). The SJB receives this ground signal and activates the vehicle alarm.

The SJB monitors the door disarm switch on circuit CRT19 (GN/VT). When the door lock cylinder is turned to unlock, the door disarm switch completes the ground through circuit GD133 (BK). This signals the SJB to cancel the alarm function.

The SJB monitors the hood switch on circuit CPL25 (BU/OG). When an unauthorized intrusion to the engine compartment occurs, the hood switch removes the ground from circuit GD120 (BK/GN), and the SJB activates the vehicle alarm.

The SJB monitors the luggage compartment lid/liftgate ajar switch on circuit CPL58 (GY/OG). When an unauthorized intrusion to the luggage compartment occurs, the luggage compartment lid/liftgate ajar switch opens, removing the ground through circuit GD147 (BK/VT), and the SJB activates the vehicle alarm.

When the SJB activates the vehicle alarm, the horn activates on/off repeatedly, and the turn signal lamps flash on/off repeatedly.

DTC B1331 (Decklid Ajar Rear Door Circuit Failure) - sets when an open is detected on circuit CPL58 (GY/OG).

DTC B1520 (Hood Switch Circuit Open) - sets when an open is detected on circuit CPL25 (BU/OG) or circuit GD120 (BK/GN).

DTC B2100 (Door Driver Key Cylinder Switch Failure) - sets when circuit CRT19 (GN/VT) is shorted to ground for greater than 2 minutes.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door ajar switch
- Door disarm switch
- Hood switch
- Luggage compartment lid/liftgate ajar switch
- RKE transmitter (part of IKT key)
- Keyless entry keypad
- SJB
