Checking the power supply
Check interior fuse 24 (11C/24:2).
Check the wire between combined instrument power supply relay (2/29) 3 and interior fuse 24 (11C/24:2) for an open circuit as described in Open-circuit, intermittent faults , and for a short circuit to ground as described in Short-circuit to ground, intermittent faults .
Check that the relay is not defective.
Check and measure wire between combined instrument 6 and handbrake contact 1 for a short circuit to ground as described in Short-circuit to ground, intermittent faults .
Check the wire between combined instrument 1 and combined instrument power supply relay (2/29) 1 for an open circuit as described in Open-circuit, intermittent faults , and a short circuit to ground as described in Short-circuit to ground, intermittent faults .
Check the wire between combined instrument 14 and ground for an open circuit as described in Open-circuit, intermittent faults , and for a short circuit to voltage supply as described in Short-circuit to supply voltage, intermittent faults .
Do the necessary corrective action.
