For a complete wiring diagram Refer to Section 8W.When Monitored:With the ignition on.Set Condition:If the Anti-Lock Brakes Module detects too many CAN Bus off events on the Dynamics Sensor Data Link circuits.Possible CausesWIRING HARNESS, TERMINAL, CONNECTOR DAMAGE(D52) DYNAMICS SENSOR HIGH DATA LINK CIRCUIT SHORTED TO GROUND, VOLTAGE, OR OPEN(D51) DYNAMICS SENSOR LOW DATA LINK CIRCUIT SHORTED TO GROUND, VOLTAGE, OR OPENDYNAMICS SENSORANTI-LOCK BRAKES MODULE1. 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 2NoThe condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.Refer to the ABS-INTERMITTENT CONDITION TEST. (Refer to 5 - BRAKES - DIAGNOSIS AND TESTING). 2. INSPECT RELATED WIRING HARNESS, TERMINALS, & CONNECTORSVisually inspect the related wiring harness. Look for any pinched, chafed, pierced, and partially broken wires.Visually inspect the related wiring harness connectors. Look 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 THE (D52) DYNAMICS SENSOR HIGH DATA LINK CIRCUIT FOR A SHORT TO VOLTAGE

Disconnect the Anti-Lock Brakes Module harness connector.Disconnect the Dynamics Sensor harness connector. Turn the ignition on.Measure the voltage of the (D52) Dynamics Sensor High Data Link circuit.Is there any voltage present?YesRepair the (D52) Dynamics Sensor High Data Link circuit for a short to voltage.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoGo To 44. CHECK THE (D52) DYNAMICS SENSOR HIGH DATA LINK CIRCUIT FOR A SHORT TO GROUND

Turn the ignition off.Measure the resistance of the (D52) Dynamics Sensor High Data Link circuit between ground and the Dynamics Sensor harness connector.Is the resistance below 5.0 ohms?YesRepair the (D52) Dynamics Sensor High Data Link circuit for a short to ground.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoGo To 55. CHECK THE (D52) DYNAMICS SENSOR HIGH DATA LINK CIRCUIT FOR AN OPEN

Measure the resistance of the (D52) Dynamics Sensor High Data Link circuit between the Dynamics Sensor harness connector and the Anti-Lock Brakes Module harness connector.Is the resistance below 5.0 ohms?YesGo To 6NoRepair the (D52) Dynamics Sensor High Data Link circuit for an open.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).6. CHECK THE (D51) DYNAMICS SENSOR LOW DATA LINK CIRCUIT FOR A SHORT TO VOLTAGE

Turn the ignition on.Measure the voltage of the (D51) Dynamics Sensor Low Data Link circuit.Is there any voltage present?YesRepair the (D51) Dynamics Sensor Low Data Link circuit for a short to voltage.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoGo To 77. CHECK THE (D51) DYNAMICS SENSOR LOW DATA LINK CIRCUIT FOR A SHORT TO GROUND

Turn the ignition off.Measure the resistance of the (D51) Dynamics Sensor Low Data Link circuit between ground and the Dynamics Sensor harness connector.Is the resistance below 5.0 ohms?YesRepair the (D51) Dynamics Sensor Low Data Link circuit for a short to ground.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoGo To 88. CHECK THE (D51) DYNAMICS SENSOR LOW DATA LINK CIRCUIT FOR AN OPEN

Measure the resistance of the (D51) Dynamics Sensor Low Data Link circuit between the Dynamics Sensor harness connector and the Anti-Lock Brakes Module harness connector.Is the resistance below 5.0 ohms?YesGo To 9NoRepair the (D51) Dynamics Sensor Low Data Link circuit for an open.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).9. REPLACE DYNAMICS SENSOR & VERIFY IF DTC IS STILL ACTIVEReplace the Dynamics Sensor in accordance with the Service Information. Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).Turn the ignition on.With the scan tool, erase ABS DTCs.Cycle the ignition switch.Ensure brake capability is available before road testing.Test drive the vehicle by turning the vehicle left or right in a curving manner at a velocity between 10 and 25 km/h (6 and 15 mph). Park the vehicle.With the scan tool, read ABS DTCs.Does this DTC reset?YesReplace the Anti-Lock Brakes Module in accordance with the Service Information.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).NoPerform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
