2. Check continuity between ECM harness connector M118 termi-
nals 95 (G/R) and 87 (GY/R).
OK or NG
OK >> GO TO 3.
NG >> Repair harness between ECM and harness connector
M75.
3. CHECK HARNESS FOR SHORT CIRCUIT
Check continuity between ECM harness connector M118 terminals
95 (G/R), 87 (GY/R) and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness between ECM and harness connector
M75.
4. CHECK HARNESS FOR SHORT CIRCUIT

2. Check continuity between ABS actuator and electric unit (control
unit) harness connector E69 terminals 20 (W) and 23 (R).
OK or NG
OK >> GO TO 5.
NG >> Repair harness between ABS actuator and electric unit
(control unit) and harness connector E116.
5. CHECK HARNESS FOR SHORT CIRCUIT
Check continuity between ABS actuator and electric unit (control
unit) harness connector E69 terminals 20 (W), 23 (R) and ground.
OK or NG

connector M75
7. CHECK HARNESS FOR SHORT CIRCUIT
Check continuity between combination meter harness connector
M44 terminals 22 (W), 23 (R) and ground.
OK or NG
OK >> GO TO 8.
NG >> Check the following harness. If any harness is dam-
aged, repair the harness.

8. CHECK ECM AND COMBINATION METER INTERNAL CIRCUIT
Check components inspection. Refer to LAN-26, "
CHECK ECM AND COMBINATION METER INTERNAL
CIRCUIT" .
OK or NG
OK >> Connect all the connectors and diagnose again. Refer to LAN-14, "Work Flow" .
NG >> Replace ECM and/or combination meter.

1. Print all the data of “SELF-DIAG RESULTS” for “ENGINE”, “ABS” and “ALL MODE AWD/4WD” displayed
on CONSULT-II.
2. Print all the data of “CAN DIAG SUPPORT MNTR” for “ENGINE”, “ABS” and “ALL MODE AWD/4WD” dis-
played on CONSULT-II.
3. Attach the printed sheet of “SELF-DIAG RESULTS” and “CAN DIAG SUPPORT MNTR” onto the check
sheet. Refer to LAN-31, "
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-31, "
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-32, "
CHECK SHEET
RESULTS (EXAMPLE)" .
