VERIFY WHETHER MALFUNCTION IS IN WIRING
HARNESS (BETWEEN INSTRUMENT CLUSTER
POWER SUPPLY AND INSTRUMENT CLUSTER FOR
CONTINUITY) OR ELSEWHERE
Switch the ignition to ON.
Measure the voltage at the instrument
cluster terminal 2S (wiring harness-
side).
Is the voltage
approx. 12 V
?
YesGo to the next step.
No Inspect for open circuit between
instrument cluster and ignition.
Repair or replace the wiring harness for a
possible open circuit as necessary.

VERIFY WHETHER MALFUNCTION IS IN WIRING
HARNESS (BETWEEN INSTRUMENT CLUSTER AND
GROUND FOR CONTINUITY) OR INSTRUMENT
CLUSTER
Switch the ignition to off.
Disconnect the instrument cluster
connector.
Inspect for continuity between
instrument cluster terminal 2K (wiring
harness-side) and body ground.
Is there continuity?
YesReplace the instrument cluster. (Open

No If communication error message is
displayed on the M-MDS (IDS) screen:
Go to the next step.
If communication error message is not
displayed:
Go to Step 9.

INSPECT DSC HU/CM POWER SUPPLY FUSE
Inspect the DSC HU/CM ignition power
supply fuse.
Is the fuse normal?
YesGo to the next step.
No Inspect the blown fuse’s circuit for short to
ground.
Repair or replace the wiring harness for a
possible short to ground as necessary.
Install appropriate amperage fuse.
