Pinpoint Test Al : U3000:41: Notes
Diagnostic Overview
U3000:41
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
When the IVD Initialization procedure is carried out the ABS module calculates and stores an offset value for the stability sensors. The ABS module also recalculates and stores this stability sensor offset value when the ignition is set to OFF. This offset value is used by the ABS module for correct operation of the vehicle stability control systems; ESC, RSC ® and Curve Control.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U3000:41 | Control Module: General Checksum Failure | When the ignition is set to ON, the ABS module reads the stored sensor calibration values and calculates a new offset value. If this offset value does not match what was previously stored in memory, the ABS module sets a DTC. |
Possible Causes
- Wiring, terminals or connectors
- Low vehicle battery voltage
- Incorrect or incomplete PMI
- Incorrect or incomplete IVD Initialization
- ABS module
- RCM
