Checking Power Supply And Ground
Check fuse F18 in the fusebox in the engine compartment.
Check the fuse in the central electronic module (CEM) for the supply relay (same relay as for the interior lighting) to the driver information module (DIM).
If the fuse has blown, check the circuit after the fuse before replacing the fuse. Check for a short-circuit to ground. Then replace the fuse. For further information about the circuit after the fuse, refer to the appropriate wiring diagram.
Check the cable between the fusebox and the power supply relay for the driver information module (DIM). Check for an open-circuit.
Check the cable between the power supply relay and the driver information module (DIM). Check for an open-circuit.
Check the ground lead between the driver information module (DIM) and the ground terminal. Check for an open-circuit. Also check the ground terminal. Check for contact resistance and oxidation.
Check the connector and the cable harness behind the dashboard. Check for damage.
Remedy as necessary.
