Pinpoint Test
- VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
- Is an observable symptom present?
- Yes: GO to step 2 .
- No: The system is operating normally at this time. The Diagnostic Trouble Code (DTC) may have been set due to high network traffic or an intermittent fault condition.
- CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Using a scan tool, perform a network test.
- Does the Body Control Module (BCM) pass the network test?
- Yes: GO to step 3 .
- No: REFER to DIAGNOSTIC ROUTINE I .
- RETRIEVE THE RECORDED Diagnostic Trouble Codes (DTCs) FROM THE Body Control Module (BCM) MODULE SELF-TEST
- Using a scan tool, perform the Body Control Module (BCM) self-test.
- Is Diagnostic Trouble Code (DTC) U3003:16 or Diagnostic Trouble Code (DTC) U3003:17 recorded?
- Yes: REFER to DIAGNOSTIC ROUTINE H or REFER to DIAGNOSTIC ROUTINE I .
- No: GO to step 4 .
- Using a scan tool, perform the Body Control Module (BCM) self-test.
- RETRIEVE THE RECORDED Diagnostic Trouble Codes (DTCs) FROM THE Head Up Display (HUD) MODULE SELF-TEST
- Using a scan tool, perform the Head Up Display (HUD) module self-test.
- Is Diagnostic Trouble Code (DTC) U3003:16 or Diagnostic Trouble Code (DTC) U3003:1C recorded?
- Yes: REFER to DIAGNOSTIC ROUTINE E or REFER to DIAGNOSTIC ROUTINE F .
- No: GO to step 5 .
- Using a scan tool, perform the Head Up Display (HUD) module self-test.
- RECHECK THE Head Up Display (HUD) MODULE Diagnostic Trouble Codes (DTCs)
- Using a scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Repeat the Head Up Display (HUD) module self-test.
- Is Diagnostic Trouble Code (DTC) U0140:00 still present?
- Yes: GO to step 6 .
- No: The system is operating correctly at this time. The Diagnostic Trouble Code (DTC) may have been set due to high network traffic or an intermittent fault condition.
NOTE: If new modules were installed prior to the Diagnostic Trouble Code (DTC) being set, the module configuration can be incorrectly set during the Programmable Module Installation (PMI) or the Programmable Module Installation (PMI) may not have been carried out. - CHECK FOR Diagnostic Trouble Code (DTC) U0140:00 SET IN OTHER MODULES
- Clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a scan tool, perform self-test.
- Retrieve the continuous memory Diagnostic Trouble Codes (DTCs) from all modules.
- Is Diagnostic Trouble Code (DTC) U0140:00 set in other modules?
- Yes: INSTALL a new Body Control Module (BCM). REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) or REFER to BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) .
- No: INSTALL a new Head Up Display (HUD) module. REFER to HEAD UP DISPLAY (HUD) MODULE .
