Are any battery voltage or charging system related Diagnostic Trouble Codes (DTCs) retrieved?
Yes | DIAGNOSE the charging system. Refer to the appropriate section in Group 414 for the procedure. |
|---|---|
No | GO to U4 |
U4 RECHECK THE RTM (RADIO TRANSCEIVER MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during PMI or the PMI may not have been performed. Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the RTM self-test.
Is DTC U0146:00 still present?
