Pinpoint Test E: The Luggage Compartment Lid Latch Release Is Inoperative/Does Not Operate Correctly
Refer to Wiring Diagram Set 113, Luggage Compartment Lid Release for schematic and connector information. Diagrams By Number
Normal Operation
When the Smart Junction Box (SJB) receives an open request from the luggage compartment lid switch, a Remote Keyless Entry (RKE) transmitter or the keyless entry keypad, the SJB supplies voltage to the luggage compartment lid latch which releases the latch. The luggage compartment lid latch has a dedicated ground circuit.
The SJB sends a voltage signal to the luggage compartment lid release switch through the input circuit. When the luggage compartment lid release switch is pressed, the voltage signal is routed to ground, signaling the SJB to release the luggage compartment lid. The luggage compartment lid release switch has a dedicated ground circuit.
- DTC B2667 (Liftglass Release Switch Circuit Failure) - an on-demand DTC that sets if the SJB detects a short to ground on the luggage compartment lid release switch input circuit. This code will also set if the luggage compartment lid release switch is pressed for longer than 2 minutes.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Luggage compartment lid release switch
- Luggage compartment lid latch
- SJB
PINPOINT TEST E: THE LUGGAGE COMPARTMENT LID LATCH RELEASE IS INOPERATIVE/DOES NOT OPERATE CORRECTLY
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
