DTC DESCRIPTOR

DTC B1395 02
Device Voltage Reference Circuit short to ground

CIRCUIT/SYSTEM DESCRIPTION
S3 and S4 are part of the Rear Compartment Lid Release switch. The folding top control (FTC) module uses S3 and S4 to determine whether the claws at the rear of the deck lid are latched into the deck lid or unlatched. S3 closes and supplies a 12-volt reference to the signal circuit when the claws are unlatched. S4 closes and supplies a 12-volt reference to the signal circuit when the claws are latched.

CONDITIONS FOR RUNNING THE DTC
The FTC module is active.

CONDITIONS FOR SETTING THE DTC
A short to ground is detected on the 12-volt reference or signal circuits of S3 and S4.

ACTION TAKEN WHEN THE DTC SETS
The top is disabled.

CONDITIONS FOR CLEARING THE DTC
The fault is no longer present and the top completes one cycle.

DIAGNOSTIC AIDS
A short to B+ may damage S3 or S4.

CIRCUIT/SYSTEM TESTING
1. Disconnect FTC Module C 2.
2. Probe the signal circuit of S3 with a test lamp connected to B+. The test lamp should not illuminate.
- If the test lamp illuminates, repair a short to ground on the signal circuit.
3. Probe the signal circuit of S4 with a test lamp connected to B+. The test lamp should not illuminate.
- If the test lamp illuminates, repair a short to ground on the signal circuit.
4. Remove the Rear Compartment Lid Release Switch.
5. Test for continuity between pin C and pin A. There should not be continuity.
- If continuity is found, replace the Rear Compartment Lid Release switch.
6. Test for continuity between pin C and pin B. There should not be continuity.
- If continuity is found, replace the Rear Compartment Lid Release switch.
7. If circuits test OK, replace the FTC Module.
