Pinpoint Tests

Pinpoint Test A: The Alarm System Does Not Operate Correctly

Normal Operation - Integrated Keyhead Transmitter (IKT)

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, the driver door lock cylinder or the door lock control switch (with the door open, then closed). The SJB (Smart Junction Box) disarms the alarm when an unlock signal is received from the RKE (Remote Keyless Entry) transmitter, the keyless entry keypad or if the ignition is turned to the ON position.

With the anti-theft perimeter alarm system armed, the SJB (Smart Junction Box) monitors the door ajar switches on circuits CPL26 (LH front door), CPL31 (RH front door), CPL36 (LH rear door) and CPL39 (RH rear door). When an unauthorized intrusion to the passenger compartment occurs, the applicable door ajar switch completes the circuit to ground. The SJB (Smart Junction Box) receives this ground signal and activates the vehicle alarm.

The SJB (Smart Junction Box) monitors the hood switch on circuit CPL25. When an unauthorized intrusion to the engine compartment occurs, the hood switch removes the ground from circuit GD123, and the SJB (Smart Junction Box) activates the vehicle alarm.

The SJB (Smart Junction Box) monitors the luggage compartment lid ajar switch on circuit CPL58. When an unauthorized intrusion to the luggage compartment occurs, the luggage compartment lid ajar switch opens, removing the ground through circuit GD149, and the SJB (Smart Junction Box) activates the vehicle alarm.

When the SJB (Smart Junction Box) activates the vehicle alarm, the horn sounds on/off repeatedly, and the turn signal lamps flash on/off repeatedly.

There is no visual (or audible) indicator of the alarm system arming or disarming.

Intelligent Access (IA)

The Remote Function Actuator (RFA) module arms the alarm (after 20 seconds have elapsed) when a lock signal is received from the RKE (Remote Keyless Entry) transmitter (part of the Intelligent Access (IA) key), the keyless entry keypad, the driver door lock cylinder or the door lock control switch (with the door open, then closed). The RFA (Remote Function Actuator) module disarms the alarm when an unlock signal is received from the RKE (Remote Keyless Entry) transmitter, the keyless entry keypad, the door disarm switch (by manually unlocking the door using a key) or if the ignition is turned to the ON mode.

With the anti-theft perimeter alarm system armed, the RFA (Remote Function Actuator) module monitors the door ajar switches on circuits CPL26 (LH front door), CPL31 (RH front door), CPL36 (LH rear door) and CPL39 (RH rear door). When an unauthorized intrusion to the passenger compartment occurs, the applicable door ajar switch completes the circuit to ground. The RFA (Remote Function Actuator) module receives this ground signal and sends a message over the MS-CAN (Medium Speed Controller Area Network) to the SJB (Smart Junction Box), instructing it to activate the vehicle alarm.

The Driver Door Module (DDM) monitors the door disarm switch on circuit CRT19. When the door lock cylinder is turned to unlock, the door disarm switch completes the ground through circuit GD133. This signals the DDM (Driver Door Module) to send a message over the MS-CAN (Medium Speed Controller Area Network) to the RFA (Remote Function Actuator) module to disarm the alarm function.

The RFA (Remote Function Actuator) module monitors the hood switch on circuit CPL25. When an unauthorized intrusion to the engine compartment occurs, the hood switch removes the ground from circuit GD123, and the RFA (Remote Function Actuator) module activates the vehicle alarm.

The RFA (Remote Function Actuator) module monitors the luggage compartment lid ajar switch on circuit CPL58. When an unauthorized intrusion to the luggage compartment occurs, the luggage compartment lid ajar switch opens, removing the ground through circuit GD147, and the RFA (Remote Function Actuator) module activates the vehicle alarm.

When the RFA (Remote Function Actuator) module sends a message over the MS-CAN (Medium Speed Controller Area Network) to the SJB (Smart Junction Box) to activate the vehicle alarm, the SJB (Smart Junction Box) causes the horn to sound on/off repeatedly, and the turn signal lamps to flash on/off repeatedly.
