1. No communication with the FTC module. 2. Power folding top is inoperative. |
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. The folding top control switch has a constant battery positive voltage supplied. Pressing the folding top control switch to the open or close position will apply the battery positive voltage to the appropriate folding top control switch open or close signal circuit to the FTC module. The FTC module monitors these signal circuits to control the direction of the folding top.
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. |

⇒ | If not the specified value, test the signal circuits terminal 2 and terminal 5 for a short to voltage. If the circuits test normal, replace the FTC module. |
⇒ | If not the specified value, replace the folding top control switch. |
⇒ | If not the specified value, replace the folding top control switch. |
⇒ | If not the specified value, replace the folding top control switch. |
⇒ | If not the specified value, replace the folding top control switch. |
