Pinpoint Test BA: U0415:82

BA1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
- Yes : GO to BA2
- No : The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
BA2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform the network test.
Does the ABS module pass the network test?
- Yes : GO to BA3
- No : REFER to: COMMUNICATIONS NETWORK .
BA3 PERFORM THE RECORDED GWM (GATEWAY MODULE A) MODULE SELF-TEST
- Using a diagnostic scan tool, perform the GWM module self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes : REFER to: COMMUNICATIONS NETWORK .
- No : GO to BA4
BA4 PERFORM THE RECORDED BCM (BODY CONTROL MODULE) MODULE SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes : REFER to: BODY CONTROL MODULE (BCM) .
- No : GO to BA5
BA5 PERFORM THE RECORDED ABS (ANTI-LOCK BRAKE SYSTEM) MODULE SELF-TEST
- Using a diagnostic scan tool, perform the ABS module self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes : REFER to: ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL .
- No : GO to BA6
BA6 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes : REFER to DTC CHART: IPC .
- No : GO to BA7
BA7 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)
NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during the Programmable Module Installation (PMI), or the Programmable Module Installation (PMI) may not have been carried out.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Repeat the IPC self-test.
Is DTC U0415:82 still present?
- Yes : GO to BA8
- 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.
BA8 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0121:00 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the continuous memory self-test.
- Retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0121:00 set in the BCM or RCM ?
- Yes : INSTALL a new GWM .
  REFER to: GATEWAY MODULE A (GWM) .
  
  GO to BA9
- No : INSTALL a new IPC .
  REFER to: INSTRUMENT PANEL CLUSTER (IPC) .
BA9 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0415:82 WITH A NEW GWM (GATEWAY MODULE A) INSTALLED
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Repeat the IPC self-test.
Is DTC U0415:82 still present?
- Yes : INSTALL a new BCM .
  REFER to: BODY CONTROL MODULE (BCM) .
  
  CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the IPC self-test. If DTC U0415:82 is still present. INSTALL a new ABS module (part of the HCU).
  
  REFER to: HYDRAULIC CONTROL UNIT (HCU) .
- No : The system is operating correctly at this time. The GWM corrected the concern.
