TROUBLESHOOTING ACTIVE STABILITY & TRACTION CONTROL SYSTEM (ASTC) 35C-76 STEP 8. Resistance measurement at the A-48 connector. (3) Measure the resistance between the A-48 ASTC- ECU connector terminal No.33 and C-145 rear 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 STEP 9. Resistance measurement at the C-145 connector and measure the resistance at the (2) Disconnect the A-48 ASTC-ECU connector and F-13-1 rear differential lock detection switch (3) Measure the resistance between the C-145 rear differential lock-ECU connector terminal No.8 and OK: No continuity Q: Is the check result normal? YES : Go to Step 10. NO : Repair the wiring harness. Then go to Step STEP 10. Resistance measurement at the A-48 connector. (3) Measure the resistance between the A-48 ASTC- ECU connector terminal No.30 and C-145 rear 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 STEP 11. Resistance measurement at the A-48 (2) Disconnect the F-13-1 rear differential detection switch connector.

NO : Repair the wiring harness. Then go to Step STEP 12. Resistance measurement at the F-13-1 detection switch connector and measure the (2) Measure the resistance between the F-13-1 rear differential lock detection switch connector 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 STEP 13. Check whether the diagnosis code is position. (4) Turn the ignition switch to the "ON" position. 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 − How to Cope with Intermittent Malfunctions .). STEP 14. Check whether the diagnosis code is |
