Pinpoint Test

NOTE: Diagnostic Trouble Code (DTC) U3003:17 may be stored in the module memory due to previous battery charging or vehicle jump starting events.

CHECK FOR Diagnostic Trouble Code (DTC) B1317, B1676, P0563 (Powertrain Control Module (PCM)) OR U3003:17 SET IN OTHER MODULES
1. Ignition ON.
2. Using a scan tool, retrieve the continuous memory Diagnostic Trouble Codes (DTCs) from all modules.
  - Is DTC B1317, B1676, P0563 (Powertrain Control Module (PCM)) or U3003:17 set in more than one module?
  - Yes: REFER to SYMPTOM CHART: CHARGING SYSTEM to diagnose an overcharging condition.
  - No: GO to step 2 .
CHECK THE BATTERY VOLTAGE
1. Turn off all interior/exterior lights and accessories.
2. Start and run the engine at approximately 2,000 Revolutions Per Minute (RPM) for 3 minutes while monitoring the battery voltage.
  - Does the battery voltage rise to 15.5 volts or higher?
  - Yes: REFER to SYMPTOM CHART: CHARGING SYSTEM to diagnose an overcharging condition.
  - No: GO to step 3 .
RECHECK FOR Diagnostic Trouble Codes (DTCs) U3003:17
1. Turn the engine off.
2. Ignition ON.
3. Using a scan tool, clear the continuous memory Body Control Module (BCM) Diagnostic Trouble Codes (DTCs).
4. Carry out the Body Control Module (BCM) self-test.
  - Is DTC U3003:17 present?
  - 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: The system is operating normally at this time. The Diagnostic Trouble Code (DTC) may have been set previously during battery charging or while jump starting the vehicle.
