NG >> Check the following harness. If any harness is dam-
aged, repair the harness.

Harness between combination meter and 4WD con-
trol unit

Harness between combination meter and steering angle sensor

Harness between combination meter and harness connector M75
10. CHECK ECM AND COMBINATION METER INTERNAL CIRCUIT
Check components inspection. Refer to LAN-129, "
CHECK ECM AND COMBINATION METER INTERNAL
CIRCUIT" .
OK or NG
OK >> Connect all the connectors and diagnose again. Refer to LAN-107, "Work Flow" .
NG >> Replace ECM and/or combination meter.
Component InspectionEKS00LVY
CHECK ECM AND COMBINATION METER INTERNAL CIRCUIT

Remove ECM and combination meter from vehicle.

Check resistance between ECM terminals 94 and 86.

Check resistance between combination meter terminals 22 and
23.22 (W) - 23 (R) : Continuity should not exist.

Work FlowEKS00NL2
1. Print all the data of “SELF-DIAG RESULTS” for “ENGINE” and “ABS” displayed on CONSULT-II.
2. Print all the data of “CAN DIAG SUPPORT MNTR” for “ENGINE” and “ABS” displayed on CONSULT-II.
3. Attach the printed sheet of “SELF-DIAG RESULTS” and “CAN DIAG SUPPORT MNTR” onto the check
sheet. Refer to LAN-134, "
CHECK SHEET" .
4. Based on the results of “CAN DIAG SUPPORT MNTR”, put a check marks onto the items with “NG” or
“UNKWN” in the check sheet table. Refer to LAN-134, "
CHECK SHEET" .
NOTE:

If a check mark is put on “NG” on “INITIAL DIAG (Initial diagnosis)”, replace the control unit.

The “CAN DIAG SUPPORT MNTR” items, which are not in check sheet table, are not related to diag-
nostic procedure on service manual.
So it is not necessary to check the status of the “CAN DIAG SUPPORT MNTR” items not in check
sheet table.
5. According to the check sheet results (example), start inspection. Refer to LAN-135, "
CHECK SHEET
RESULTS (EXAMPLE)" .
