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.
The FTC module is operational.
An open is detected on the signal circuit of S3.
The top is disabled.
The fault is no longer present and the top completes one cycle.
• | A weak battery may cause DTC B367B 59 to set. |
• | A short to B+ may damage S3. |

⇒ | If the test lamp does not illuminate, test the 12-volt reference circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the FTC module. |
⇒ | If the test lamp does not illuminate, test the signal circuit for an open/high resistance. If the circuit test is normal, replace the FTC module. |
