1. Trunk Release Inoperative |
The folding top control (FTC) module checks the integrity of the signal circuits from the rear compartment lid release close switch at least once every 300 milliseconds. The rear compartment lid release close switch has a constant battery positive voltage supplied. Pressing the rear compartment lid release close switch will apply the battery positive voltage to the rear compartment lid release close switch signal circuit to the FTC module. The FTC module monitors the signal request and will operate the rear compartment lid when battery positive voltage is received.
• | Battery voltage must be between 9-16 volts. |
• | DTC B1327 is not set as current. |
The FTC module detects a short to battery in the rear compartment lid release switch circuit for more than 5 seconds.
The rear compartment lid pull-down feature will be inactive from the rear compartment lid release switch.
• | The condition responsible for setting the DTC no longer exists. |
• | A history DTC will clear once 50 consecutive malfunction-free ignition cycles have occurred. |
A rear compartment lid release switch that is held or stuck in the closed position for more than 5 seconds will set DTC B3641.

⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
⇒ | If the test lamp is always ON, test the signal circuit for a short to voltage. If the circuit tests normal, test or replace the rear compartment lid release switch. |
⇒ | If the test lamp is always OFF, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, test or replace the rear compartment lid release switch. |
⇒ | If not the specified value, replace the rear compartment lid release switch. |
⇒ | If greater than the specified range, replace the rear compartment lid release switch. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
