Intermittent Fault

Check the wiring between control module terminal A59 (#A59) and transmission connector #S (#A16) for an intermittent open-circuit according to OPEN-CIRCUIT, INTERMITTENT FAULTS , an intermittent short-circuit to ground according to SHORT-CIRCUIT TO GROUND, INTERMITTENT FAULTS , and an intermittent short-circuit to supply voltage according to SHORT-CIRCUIT TO SUPPLY VOLTAGE, INTERMITTENT FAULTS and contact resistance and oxidation according to CONTACT RESISTANCE AND OXIDATION .

Also check the wiring between control module terminal 41 (#A41) and transmission connector #V (#A17) for an intermittent open-circuit according to OPEN-CIRCUIT, INTERMITTENT FAULTS , an intermittent short-circuit to ground according to SHORT-CIRCUIT TO GROUND, INTERMITTENT FAULTS , and an intermittent short-circuit to supply voltage according to SHORT-CIRCUIT TO SUPPLY VOLTAGE, INTERMITTENT FAULTS and contact resistance and oxidation according to CONTACT RESISTANCE AND OXIDATION .

Remedy as necessary.
