DIAGNOSIS CODE SET CONDITION PROBABLE CAUSES • Malfunction of the G and yaw rate sensor • Damaged wiring harness or connector • Malfunction of the hydraulic unit (integrated with ASTC-ECU) DIAGNOSIS PROCEDURE STEP 1. M.U.T.-III CAN bus diagnosis Q: Is the check result normal? YES : Go to Step 3. NO : Repair the CAN bus lines (Refer to GROUP − CAN Bus Diagnostics table ). On completion, go to Step 2. STEP 2. Diagnosis code recheck after resetting Q: Is the diagnosis code No.C1223 set? YES : Go to Step 3. NO : This diagnosis is complete. STEP 3. Connector check: C-144 G and yaw rate Q: Is the check result normal? YES : Go to Step 4. NO : Repair the defective connector. Then go to STEP 4. Resistance measurement at the C-144 G |
