Diagnostic Overview

DTC U1000:00 - Body Control Module (BCM)

Normal Operation and Fault Conditions

The BCM (Body Control Module) controls the output of several vehicle systems by means of solid state drivers. When an overload occurs on any of these drivers, a DTC (Diagnostic Trouble Code) 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 (Diagnostic Trouble Code) U1000:00 sets along with the DTC (Diagnostic Trouble Code) associated with the affected circuit.DTC Fault Trigger Conditions






Pinpoint Test

1. REVIEW THE DTCs (Diagnostic Trouble Codes)

1. Review the DTCs (Diagnostic Trouble Codes) from the BCM (Body Control Module) self-test.

Are any other DTCs (Diagnostic Trouble Codes) present besides U1000:00 or U3000:49?








2. REPEAT THE BCM (Body Control Module) SELF-TEST

1. Ignition ON.

2. Using a scan tool, clear the DTCs (Diagnostic Trouble Codes) and repeat the BCM (Body Control Module) self-test.

Is DTC (Diagnostic Trouble Code) U3000:49 present?
