Pinpoint Test P: U1000:00
- Normal Operation and Fault Conditions
The BCM uses solid state drivers, referred to as Field Effect Transistors (FET) to control the output of several vehicle systems. When an overload occurs on any of these drivers, the BCM disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to three 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 BCM U1000:00 Solid State Driver Protection Active - Driver Disabled: No Sub Type Information A continuous memory DTC that sets when the BCM has disabled a circuit due to a repetitive circuit overload and a progressive threshold is met. Possible Sources
- BCM output circuit short
- BCM
- P1 REVIEW THE DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Review the Diagnostic Trouble Codes (DTCs) from the BCM self-test.
Are any Diagnostic Trouble Codes (DTCs) present besides U1000:00?
Yes CORRECT the Diagnostic Trouble Codes (DTCs). REFER to: DTC Charts: BCM . No GO to P2 - P2 REPEAT THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Repeat the BCM 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 BCM. REFER to Body Control Module (BCM) No The system is operating correctly at this time. The circuit short has been repaired.
