Diagnostic Fault Information






Circuit/System Description

S1 is the folding top header latch cylinder sensor. The folding top control (FTC) module uses S1 to determine if the folding top header latch cylinder is in the latched or unlatched position. S1 is a hall effect sensor that becomes active when the cylinder is in the unlatched position.

Conditions for Running the DTC

The FTC module is active.

Conditions for Setting the DTC

A short to ground, short to voltage, or open is detected on the signal circuit of S1.

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 weak battery may cause DTC B1296 58 or DTC B1296 59 to set.

Circuit/System Testing

1. Disconnect the harness connector at S1.
2. Ignition ON, verify a test lamp illuminates between the 12-volt reference circuit terminal 2 and ground.

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

3. Connect a 3A fuse jumper wire between the 12-volt reference circuit terminal 2 and the signal circuit terminal 1. Verify the scan tool Folding Top Header Latch Cyl. parameter is Latched.

• If not the specified value, test the signal circuit for a short to voltage, short to ground, or an open/high resistance. If the circuit tests normal, replace the FTC module.

4. If all circuits test normal, test or replace S1.
