Pinpoint Test E: DTC U1000: 00

Body Control Module (BCM)

Pinpoint Tests

Pinpoint Test E: DTC U1000: 00

Normal Operation

The Body Control Module (BCM) controls the output of several vehicle systems by means of solid state drivers. When an overload occurs on any of these drivers, a DTC sets. The module also 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 the each threshold, DTC U1000:00 sets along with the DTC associated with the affected circuit.

- DTC U1000: 00 (Solid State Driver Protection Activated - Driver Disabled: No Sub Type Information) - sets when the BCM has disabled a circuit due to a repetitive circuit overload and a progressive threshold is met.

This pinpoint test is intended to diagnose the following:

- Output circuit short
- BCM

PINPOINT TEST E: DTC U1000: 00

-------------------------------------------------
E1 REVIEW THE DTCs

- Review the DTCs from the BCM self-test.
- Are any other DTCs present, besides U1000:00 or U3000:49?

Yes
REFER to the Body Control Module (BCM) DTC chart. Body Control Module (BCM)

No
GO to E2.

-------------------------------------------------
E2 REPEAT THE BCM SELF-TEST

- Ignition ON.
- Enter the following diagnostic mode on the scan tool: BCM Self-Test.
- Clear the DTCs and repeat the BCM self-test.
- Is DTC U3000:49 present?

Yes
INSTALL a new BCM. REFER to Body Control Module (BCM) Service and Repair. TEST the system for normal operation.

No
The system is operating correctly at this time. The circuit short has been repaired.
