INSPECTION
|
ACTION
|
1
|
VERIFY WHETHER MALFUNCTION IS IN COMMON POWER SUPPLY OF WARNING LIGHTS AND INDICATOR LIGHTS, OR IN OTHER WARNING LIGHTS AND INDICATOR LIGHTS
• Do other warning and indicator lights illuminate when the ignition switch is turned to the ON position?
|
Yes
|
Go to step 4.
|
No
|
Go to the next step.
|
2
|
INSPECT INSTRUMENT CLUSTER POWER SUPPLY FUSE
• Is the instrument cluster ignition power supply fuse normal?
|
Yes
|
Go to the next step.
|
No
|
Inspect for a short to ground on the circuit with the blown fuse.
Repair or replace if necessary.
Install appropriate amperage fuse.
|
*3
|
VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (INSPECT FOR CONTINUITY BETWEEN INSTRUMENT CLUSTER POWER SUPPLY AND INSTRUMENT CLUSTER) OR INSTRUMENT CLUSTER
• Turn the ignition switch to the ON position.
• Measure the voltage at instrument cluster connector (12-pin) terminal 1G.
• Is the voltage approx. 12 V?
|
Yes
|
Replace the instrument cluster (open circuit in instrument cluster).
|
No
|
Inspect for an open circuit between the instrument cluster and ground.
Repair or replace if necessary.
|
4
|
CONFIRM DTC U1900 USING M-MDS
• Retrieve DTCs from the PCM, ABS and instrument cluster.
• Is DTC U1900 retrieved?
|
Yes
|
Go to the next step.
|
No
|
Inspect the instrument cluster. If normal, go to Step 6.
|
5
|
CONFIRM DTCS U0121, U0100 AND U0214 USING M-MDS:
• Retrieve DTCs from the instrument cluster.
• Are DTCs U0121, U0100 and U0214 retrieved?
|
Yes
|
Replace the instrument cluster (open circuit in instrument cluster).
|
No
|
Inspect network communication for related system malfunction.
Repair or replace if necessary.
|
6
|
CONFIRM DTC B2477 FOR INSTRUMENT CLUSTER USING M-MDS
• Is DTC B2477 retrieved?
|
Yes
|
Perform instrument cluster configuration.
|
No
|
Replace the ABS HU/CM.
