Pinpoint Test E: DTC U1000: 00

Body Control Module (BCM)

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 (Body Control Module) 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 (Body Control Module)

PINPOINT TEST E : DTC U1000: 00

E1 REVIEW THE DTCs

- Review the DTCs from the BCM (Body Control Module) self-test.

Are any other DTCs present, besides U1000:00 or U3000:49?

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

No
GO to E2.

E2 REPEAT THE BCM (Body Control Module) SELF-TEST

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: BCM (Body Control Module) Self-Test.

- Clear the DTCs and repeat the BCM (Body Control Module) self-test.

Is DTC U3000:49 present?

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

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