Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Test G: U1000:00
- Normal Operation and Fault Conditions
The BCMC uses solid state drivers to control the output of several systems. When an overload occurs on any of these drivers, the BCMC disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to 3 progressive thresholds established for each circuit. At each threshold, DTC U1000:00 sets along with the DTC associated with the affected circuit. For additional information, REFER to: Module Controlled Functions - System Operation and Component Description .
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition BCMC U1000:00 Solid State Driver Protection Active -Driver Disabled: No Sub Type Information A continuous memory DTC that sets when the BCMC has disabled a circuit due to a repetitive circuit overload and a progressive threshold is met. Possible Sources
- BCMC (BJB)
- G1 REVIEW THE DIAGNOSTIC TROUBLE CODES (DTCS)
- Review the Diagnostic Trouble Codes (DTCs) from the BCMC self-test.
Are any Diagnostic Trouble Codes (DTCs) present besides U1000:00?
Yes CORRECT the Diagnostic Trouble Codes (DTCs). REFER to the BCMC DTC Chart. No GO to G2 - G2 REPEAT THE BCMC (BODY CONTROL MODULE C) SELF-TEST
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Repeat the BCMC self-test.
Is DTC U1000:00 still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCMC. REFER to: Body Control Module C (BCMC) . No The system is operating correctly at this time. The circuit short has been repaired.
