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.
