Automatic transmission vehicles with a VIN of JM1FD3***P0200001 through
JM1FD3***P0210498.

DESCRIPTION

Hard restart after running the vehicle at high speeds on hot days. Vehicle restarts easily after engine compartment cools down.

This hard start condition is caused when heat from the engine increases the electrical resistance in the starter wire. This decreases the amount current received at the "S" terminal on the starter.

To correct this problem, the starter harness length has been changed and the amount of current applied to the "S" terminal during starting increased.

REPAIR PROCEDURE

If the condition exists, install the countermeasure starter wire harness.

1. Disconnect the vehicle battery.

2. Raise the vehicle on a hoist or raise the front end with ramps.





3. Disconnect the connectors at the starter.





4. Connect countermeasure harness FDY1 67 SHO as shown.





5. Tape off OEM starter solenoid wire. Secure countermeasure harness with 4 tie-wraps E018 67C92. Confirm there is no interference between the brake and fuel lines.
