Checking for an open-circuit, contact resistance and oxidation

Check ground terminals 31/32 and 31/33 and cables between ground terminals and control module #A20 and #A29 for an open-circuit according to Open-circuit, permanent faults , and contact resistance and oxidation according to Contact resistance and oxidation .

Check ground lead between battery and bodywork for an open-circuit according to Open-circuit, permanent faults , and contact resistance and oxidation according to Contact resistance and oxidation .
