- Carry out the BCM self-test.
- Record all DTCs from the BCM self-test.
- Is DTC U3003:16 or U3003:17 present?
Yes No DIAGNOSE the BCM DTC. REFER to DIAGNOSIS AND TESTING Go to D8. - D8: CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN NOTE: If new modules were installed prior to the DTC being set, the module configuration can be incorrectly set during the PMI or the PMI may not have been carried out.
- Operate the system and determine if the observable symptom is still present.
- Is the observable symptom still present?
Yes No Go to D9. The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration. - D9: CHECK FOR COMMUNICATION DTCS IN OTHER MODULES
- Ignition ON, engine OFF.
- Clear the ABS DTCs.
- Retrieve the continuous memory DTCs.
- Is DTC U0140:xx, U0422:xx or U3003:08 set in 1 or more modules in addition to the ABS module?
Yes No Go to D10. Go to D11. - D10: VERIFY BCM OPERATION
- Ignition OFF.
- ABS Module connector disconnected.
- Using a good light source, inspect all disconnected electrical connectors for the following:
- corrosion - install new connector or terminal and clean the module pins
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary
- spread terminals - install new terminals as necessary
- ABS Module connector connected. Make sure the connector seats and latches correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes No INSTALL a new BCM.
CHECK OASIS for any service articles: TSB, GSB, SSM or FSA.
If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions.
If no services articles address this concern, INSTALL a new BCM. REFER to BODY CONTROL MODULE (BCM)
ORDER a replacement BCM#2 module and INCLUDE the RVC on the form.
