1.VERIFY DTC IS ACTIVETurn the ignition on.With the scan tool, read and record ABS DTCs.With the scan tool, read and record Environmental Data (EV Data).With the scan tool, erase ABS DTCs.Cycle the ignition switch.With the scan tool, read ABS DTCs.Does this DTC reset?YesGo To 2NoPerform the ABS Intermittent Condition diagnostic procedure in this Section.Refer to the ABS-INTERMITTENT CONDITION TEST. (Refer to 5 - BRAKES - DIAGNOSIS AND TESTING)2.INSPECT RELATED WIRING HARNESS, TERMINALS, & CONNECTORSTurn the ignition off.Check all related wiring for pinched, chafed, pierced, and partially broken wires.Check all related connectors for broken, bent, pushed out, and corroded terminals.Were any problems found?YesRepair as necessary.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoGo To 33.CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT & (G94) DYNAMICS SENSOR GROUND CIRCUIT FUNCTIONDisconnect the Dynamics Sensor harness connector.Turn the ignition on.Measure the voltage between the (G4) Dynamics Sensor Supply Circuit and the (G94) Dynamics Sensor Ground Circuit.Is the voltage above 4.5 volts?YesReplace the Dynamics Sensor in accordance with the Service Information.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoGo To 44.CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT FOR HIGH RESISTANCETurn the ignition off.Disconnect the Anti-Lock Brakes Module harness connector.Measure the resistance of the (G4) Dynamics Sensor Supply circuit between the Dynamics Sensor harness connector and the Anti-Lock Brakes Module harness connector.Is the resistance below 5.0 ohms?YesGo To 5NoRepair the (G4) Dynamics Sensor Supply circuit for high resistance.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).5.CHECK (G94) DYNAMICS SENSOR GROUND CIRCUIT FOR HIGH RESISTANCEMeasure the resistance of the (G94) Dynamics Sensor Ground circuit between the Dynamics Sensor harness connector and the Anti-Lock Brakes Module harness connector.Is the resistance below 5.0 ohms?YesReplace the Anti-Lock Brakes Module in accordance with the Service Information.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoRepair the (G94) Dynamics Sensor Ground circuit for high resistance.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
