E5 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.
Check the vehicle service history for recent service actions related to the VDM or GWM. If recent service history is found:
verify the correct replacement module was installed.
HVBOM may be used to verify correct part fitment.
verify the configuration of replacement module was correct.
re-configure the module using as-built data if prior configuration is suspect.
verify the module was not obtained from a like vehicle and installed into customer vehicle.
return the swapped module to source vehicle and obtain new replacement module.
Operate the system and determine if the observable symptom is still present.
Is the observable symptom still present?
Yes | GO to E6 |
|---|---|
No | The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration. |
E6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0146:XX SET IN OTHER MODULES
Using a diagnostic scan tool, carry out the self-test for all modules.
Is DTC U0146:xx set in 1 or more modules in addition to the VDM?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new GWM. REFER to: Gateway Module A (GWM) (418-00 Module Communications Network, Removal and Installation). |
