Pinpoint Test

VERIFY THE SCAN TOOL COMMUNICATES WITH THE Powertrain Control Module (PCM)
1. Connect the scan tool.
2. Check that a vehicle session can be established using the scan tool.
  - Can a vehicle session be established?
  - Yes: GO to step 2 .
  - No: REFER to DIAGNOSTIC ROUTINE A .
CHECK THE Body Control Module (BCM) CONTINUOUS MEMORY Diagnostic Trouble Codes (DTCs)
1. Ignition ON.
2. Using a scan tool, perform BODY CONTROL MODULE (BCM) self-test.
3. Clear the Diagnostic Trouble Codes (DTCs). Repeat the Body Control Module (BCM) self-test.
  - Is Diagnostic Trouble Code (DTC) U0140:87 retrieved again?
  - Yes: GO to step 3 .
  - 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.
RETRIEVE THE RECORDED Diagnostic Trouble Codes (DTCs) FROM THE Body Control Module (BCM) SELF-TEST
1. Check for recorded Body Control Module (BCM) Diagnostic Trouble Codes (DTCs) from the self-test.
  - Is Diagnostic Trouble Code (DTC) U3003:16 or Diagnostic Trouble Code (DTC) U3003:17 recorded?
  - Yes: For Diagnostic Trouble Code (DTC) U3003:16, REFER to DIAGNOSTIC ROUTINE H .
    For Diagnostic Trouble Code (DTC) U3003:17, REFER to DIAGNOSTIC ROUTINE I .
  - No: GO to step 4 .
CHECK FOR Diagnostic Trouble Code (DTC) U0140:87 SET IN OTHER MODULES
1. Ignition ON.
2. Using a scan tool, retrieve the continuous memory Diagnostic Trouble Codes (DTCs) from all modules.
  - Is Diagnostic Trouble Code (DTC) U0140:87 set in any other module?
  - 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 Remote Function Actuator (RFA). REFER to REMOTE FUNCTION ACTUATOR (RFA) MODULE .
