Is DTC U0146:00 still present?
Yes GO to H6
No The system is operating correctly at this time. The DTC may have set due to high network traffic or an intermittent fault condition.

H6 CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN

NOTE: If new modules were installed prior to the DTC being set, the module configuration may 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 SODL, SODR, or GWM. If recent service history is found:
    • verify correct replacement module was installed
      • HVBOM may be used to verify correct part fitment
    • verify the configuration of replacement module was correct
      • re-configure module using as-built data if prior configuration is suspect
