Pinpoint Test

VERIFY THE SCAN TOOL CAN COMMUNICATE WITH THE Powertrain Control Module (PCM)
1. Connect the scan tool.
2. Ignition ON.
3. 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. Using a scan tool, perform BODY CONTROL MODULE (BCM) self-test.
2. Clear the Diagnostic Trouble Codes (DTCs). Repeat the Body Control Module (BCM) self-test.
  - Is Diagnostic Trouble Code (DTC) U0100:00 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) U0100:00 OR Diagnostic Trouble Code (DTC) U0100 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) U0100:00 or DTC U0100 set in any other module?
  - Yes: INSTALL a new Powertrain Control Module (PCM). REFER to POWERTRAIN CONTROL MODULE (PCM) . CLEAR the Diagnostic Trouble Codes (DTCs).
  - No: 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) .
