Checking the wire and relay
Check the wire between control unit 6C and relay 2/64 1 for an intermittent short circuit to voltage supply as described in Short-circuit to supply voltage, intermittent faults , contact resistance and oxidation as described in Contact resistance and oxidation and a loose connection as described in Loose connections (terminals) .
Also check the same connectors for an intermittent short circuit to voltage supply as described in Short-circuit to supply voltage, intermittent faults or for contact resistance and oxidation as described in Contact resistance and oxidation and for a loose connection as described in Loose connections (terminals) .
Check that relay 2/64 is installed correctly.
Do the necessary corrective action.
