Pinpoint Test Ah: Abs (Anti-Lock Brake System) Module DTC C0051 Steering Angle Concerns With The PSCM (Power Steering Control Module) - Electrical

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

Refer to POWER STEERING CONTROLS for schematic and connector information.

Normal Operation and Fault Conditions

Description

Description
ABS module Diagnostic Trouble Codes (DTCs) C006B:xx and C0051:xx set when the comparison between the ABS module steering angle information and the PSCM steering angle information is outside of the expected range. Both mechanical and electrical components may cause this concern.

Pinpoint Test Applicability

Pinpoint Test Applicability
This test applies to electrical concerns with the PSCM resulting in ABS module DTC C006B:xx, ABS module DTC C0051:xx or ABS false activation only.

DTC Diagnostic Strategy

DTC Diagnostic Strategy
If the module DTC list results in a large number of Diagnostic Trouble Codes (DTCs), diagnose all module hard faults first (C102D, C1B00, C200B, C200C, C200D, U2011 and U3000) before diagnosing any network faults (lost communication or invalid data). If voltage concern Diagnostic Trouble Codes (DTCs) are present, diagnose those after any module hard faults and before any network faults. Diagnose all current and active Diagnostic Trouble Codes (DTCs) before diagnosing any historic Diagnostic Trouble Codes (DTCs).

Pinpoint Test Purpose

Pinpoint Test Purpose
This pinpoint test checks both the PSCM and the associated electrical wiring which can affect the steering wheel angle comparison between the ABS module and the PSCM.
