Is DTC U0237:00 set in the ACM or audio DSP module?
Yes | GO to AS3 | |
|---|---|---|
No | The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. | |
AS3 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 Audio DSP module DACMC
Are any low or high voltage Diagnostic Trouble Codes (DTCs) recorded in the ACM, audio DSP module, or DACMC?
Yes | • For DTC U3003:16, GO to Pinpoint Test AW • For DTC U3003:17, GO to Pinpoint Test AX | |
|---|---|---|
No | GO to AS4 | |
AS4 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0237:00 SET IN MULTIPLE MODULES
Review the recorded results from the self-test.
Is DTC U0237:00 set in both the ACM and audio DSP module?
Yes | GO to AS5 | |
|---|---|---|
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. | |
AS5 CHECK FOR CORRECT DACMC (DIGITAL AUDIO CONTROL MODULE C) OPERATION
Ignition OFF. Disconnect and inspect all the ACM connectors. Repair:
Corrosion (clean module pins or install new connectors or terminals) Damaged or bent pins (install new terminals or pins) Pushed-out pins (install new pins as necessary)
Reconnect the ACM connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.
Is the concern still present?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new ACM. REFER to: Audio Front Control Module (ACM) (415-00B Information and Entertainment System - General Information - Vehicles With: Touchscreen Display, Removal and Installation). | |
|---|---|---|
No | The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. | |
