- Is the measured value within specification?
YES
- This can be an intermittent fault caused by poor contact in the sensor's and/or control module's connector. Or, control module's memory was not cleared after repair. Thoroughly check connectors for looseness, poor connection, ending, corrosion, contamination, deterioration, or damage.
- Repair or replace the relevant component(s) as necessary, and go to "VERIFICATION OF VEHICLE REPAIR ".
- Replace the Rear Camera with an usable one and check for proper operation. If it works properly, put the component in place. Then, go to "VERIFICATION OF VEHICLE REPAIR ".
NO
- Repair the fuse, power circuit, or ground circuit with an open. Then, go to "VERIFICATION OF VEHICLE REPAIR ".
