Are any low or high voltage Diagnostic Trouble Codes (DTCs) recorded in the PCM?

AK3 CHECK THE PCM (POWERTRAIN CONTROL MODULE) FOR BATTERY VOLTAGE OUT-OF-RANGE DIAGNOSTIC TROUBLE CODES (DTCS)

Using a diagnostic scan tool, perform the PCM self-test.

AK4 CHECK FOR BATTERY VOLTAGE OUT-OF-RANGE DIAGNOSTIC TROUBLE CODES (DTCS)

Using a diagnostic scan tool, perform the self-test for the following modules:

ACM DACMC

Are low or high voltage Diagnostic Trouble Codes (DTCs) recorded in the ACM or DACMC?

Yes	• For DTC U3003:16, GO to Pinpoint Test AW • For DTC U3003:17, GO to Pinpoint Test AX
No	GO to AK5

Yes

• For DTC U3003:16, GO to Pinpoint Test AW

• For DTC U3003:17, GO to Pinpoint Test AX

GO to AK5

AK5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0100:00 SET IN MULTIPLE MODULES

Review the recorded results from the self-test.

Is DTC U0100:00 set in more than one module?

Yes	GO to AK6
No	• If there is an observable symptom, REFER to: Information and Entertainment System (415-00B) . See Symptom Chart. • If there is no observable symptom, the system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
