Diagnostic Test
- VERIFY ACTIVE DTC WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
NOTE:Using the wiring diagram/schematic as a guide check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
NOTE:If after the harness inspection it appears the impact sensor connector is only seated halfway. Reseat the harness connector into the impact sensor and lock the tab. Follow the instructions below checking for active codes.
WARNING:Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
NOTE:Make sure the battery is fully charged.
- Turn the ignition on.
- With the scan tool, read ORC DTCs.
Does the scan tool display active Service Info B0096-49-RIGHT SIDE ACCELERATION SENSOR 1 - INTERNAL ELECTRONIC FAILURE, B0097-49-RIGHT SIDE ACCELERATION SENSOR 2 - INTERNAL ELECTRONIC FAILURE, U0175-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 1, U0176-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 2 , U11B0-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 4 - DTC?
Yes
- Check for all other internal and lost communication codes indicated in the right side impact sensor daisy chain wiring before diagnosing DTC U11B0-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 4. Go To The DTC Displayed. Refer to Diagnosis and Testing . If internal fault 1, internal fault 2, and lost comm fault 1, and lost comm fault 2 have been checked follow DTC U11B0-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 4. Go To 2.
NOTE:Check for the active codes and repair for the fault starting with the Internal failure code or codes, check for active or stored status. Upon fixing the right side impact sensor 1 then check the right side impact sensor 2 internal fault if status changes to stored for all codes fault is fixed if status is still active proceed to the right side impact sensor 1 loss of comm check for status of the right side impact sensor 1 code status being active. If all codes go to stored status, fault in daisy chain is fixed if code status is still active continue. Check the right side impact sensor 2 check for status of the right side impact sensor 2 code going to stored. If status of all codes goes to stored status, fault in daisy chain is fixed if code status is still active continue. Check the right side impact sensor 4, fix fault and check for status of code going to stored status.
