Test E: The Alarm System Does Not Operate Correctly - The Alarm Does Not Inhibit From The Luggage Compartment Disarm Switch
PINPOINT TEST E: THE ALARM SYSTEM DOES NOT OPERATE CORRECTLY - THE ALARM DOES NOT INHIBIT FROM THE LUGGAGE COMPARTMENT DISARM SWITCHNormal Operation
The smart junction box (SJB) monitors the luggage compartment disarm switch on circuit CRT18 (YE/GY) for a ground signal. The luggage compartment disarm switch is a normally open switch. When the key is turned to the unlock position, the disarm switch completes the circuit to ground on circuit GD171 (BK/GY) signaling the SJB that an authorized entry to the luggage compartment is occurring. The SJB inhibits the alarm from activating until the luggage compartment lid is closed, then adds the luggage compartment lid to the protected entry points.
- DTC B2108 (Trunk Key Cylinder Switch Failure) - sets when there is a short to ground in the circuit between the luggage compartment disarm switch and the SJB, or the luggage compartment disarm switch is shorted closed internally.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Luggage compartment disarm switch
- SJB
