REVERSING SENSOR SYSTEM CHASSIS ELECTRICAL 54A-226 DIAGNOSTIC FUNCTION • During the transmission/reception operation of each sensor, when the corner sensor/back sen- TROUBLESHOOTING HINT • Damaged harness wires and connectors • Sensor malfunction • Malfunction of corner sensor/back sensor-ECU DIAGNOSIS PROCEDURE STEP 1. Check the following connectors. • F-31 Rear corner sensor (RH) connector • F-34 Rear corner sensor (LH) connector • F-32 Back sensor (RH) connector • F-33 Back sensor (LH) connector • C-40 corner sensor/back sensor-ECU connector Q: Are all the connectors in good condition? YES : Go to Step 2. NO : Repair the defective connector. STEP 2. Check the following wiring harness. • Wiring harness from F-31 Rear corner sensor (RH) connector terminal No. 1, 2 to C-40 corner • Wiring harness from F-34 Rear corner sensor (LH) connector terminal No. 1, 2 to C-40 corner • Wiring harness from F-32 Back sensor (RH) con- nector terminal No. 1, 2 to C-40 corner sensor/ • Wiring harness from F-33 Back sensor (LH) con- nector terminal No. 1, 2 to C-40 corner sensor/ NOTE: Prior to the wiring harness inspection, check Q: Are all the wiring harness wires in good condition? YES : Go to Step 3. NO : Repair the wiring harness. STEP 3. Confirm which reversing sensor (corner Q: Which reversing sensor (corner sensor/back sensor) does not detect the obstacle? Go to Step 4. Rear corner sensor (LH) : Go to Step 5. Back sensor (RH) : Go to Step 6. Back sensor (LH) : Go to Step 7. STEP 4. Diagnosis code recheck Q: Is the diagnosis code set?
