B1297

DTC B1297

Circuit Description
The folding top control (FTC) module checks the integrity of the signal circuit from the rear compartment lid pulldown actuator at least once every 300 milliseconds. The rear compartment lid pulldown actuator has a constant battery positive voltage supplied. During truck or folding top operation, the rear compartment lid pulldown actuator will apply the battery positive voltage to the FTC module. The FTC uses this signal as assurance that the latch is clear of the striker.
