STEP 8. Resistance measurement at the A-48
ASTC-ECU connector and C-145 rear differential
lock-ECU connector
(1) Disconnect the A-48 ASC-ECU connector.
(2) Disconnect the C-145 rear differential lock-ECU
connector.
(3) Measure the resistance between the A-48 ASTC-
ECU connector terminal No.33 and C-145 rear
differential lock-ECU connector terminal No.10.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 9.
NO :
Repair the wiring harness. Then go to Step
15.
STEP 9. Resistance measurement at the C-145
rear differential lock-ECU connector
(1) Disconnect the C-145 rear differential lock-ECU
connector and measure the resistance at the
harness side.
(2) Disconnect the A-48 ASTC-ECU connector and
F-13-1 rear differential lock detection switch
connector.
(3) Measure the resistance between the C-145 rear
differential lock-ECU connector terminal No.8 and
body earth.
OK: No continuity
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Repair the wiring harness. Then go to Step
15.
STEP 10. Resistance measurement at the A-48
ASTC-ECU connector and C-145 rear differential
lock-ECU connector
(1) Disconnect the A-48 ASTC-ECU connector.
(2) Disconnect the C-145 rear differential lock-ECU
connector.
(3) Measure the resistance between the A-48 ASTC-
ECU connector terminal No.30 and C-145 rear
differential lock-ECU connector terminal No.8.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 11.
NO :
Repair the wiring harness. Then go to Step
15.
STEP 11. Resistance measurement at the A-48
ASTC-ECU connector and F-13-1 rear differential
lock detection switch connector
(1) Disconnect the A-48 ASTC-ECU connector.
(2) Disconnect the F-13-1 rear differential detection
switch connector.
(3) Measure the resistance between the A-48 ASTC-
ECU connector terminal No.30 and F-13-1 rear
differential detection switch connector terminal
No.2.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 12.
NO :
Repair the wiring harness. Then go to Step
15.
STEP 12. Resistance measurement at the F-13-1
rear differential lock detection switch connector
(1) Disconnect the F-13-1 rear differential lock
detection switch connector and measure the
resistance at the harness side.
(2) Measure the resistance between the F-13-1 rear
differential lock detection switch connector
terminal No.1 and body earth.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 13.
NO :
Repair the wiring harness. Then go to Step
15.
STEP 13. Check whether the diagnosis code is
reset.
(1) Turn the ignition switch to the "ON" position.
(2) Erase the diagnosis code.
(3) Turn the ignition switch to the "LOCK" (OFF)
position.
(4) Turn the ignition switch to the "ON" position.
(5) Start the engine.
(6) Turn the rear differential lock switch to the "ON"
position.
(7) Drive the vehicle more than 10 seconds at the
speed exceeds 10 km/h.
(8) Check if the diagnosis code is set.
Q: Is code No.C1292 set?
YES :
Replace the Rear differential lock-ECU
(Refer to GROUP 27
− Rear differential
lock-ECU .). Then go to Step 14.
NO :
Intermittent malfunction (Refer to GROUP
00
− How to Cope with Intermittent
Malfunctions .).
STEP 14. Check whether the diagnosis code is
reset.
(1) Turn the ignition switch to the "ON" position.
(2) Erase the diagnosis code.
(3) Turn the ignition switch to the "LOCK" (OFF)
