The folding top control (FTC) module checks the integrity of the signal circuits from the folding top control switch at least once every 300 milliseconds. Battery voltage from the 10A TILT/TELE SW/MEM SEAT MOD fuse is supplied to the folding top control switch. When either the top open or top close switch is pressed, battery voltage is applied through the switch contacts and the signal circuit to the FTC module. The FTC module then moves the folding top to the requested open or closed position.
The FTC module must be powered and can not have B1327 or B1328 set as active DTCs for this DTC to set. The battery voltage is between 9-16 volts.
• | When the FTC module detects inputs on both the folding top control switch open and close signal circuits at the same time. |
• | When the FTC module detects either of the folding top control switch open or close signal circuits active for 3 minutes or more. |
• | The folding top operation is suspended. |
• | The FTC module stores B3602 as a current and history DTC. |
• | This DTC will clear on the current status after the condition for setting the fault is corrected. |
• | A history DTC will clear after 50 consecutive ignition cycles without a fault present. |
The Rear Compartment Lid is also referenced as the Deck Lid for this vehicle.
