Diagnostic Test
1. VERIFY DTC IS ACTIVENOTE: If present, diagnose and repair DTC C2114–DYNAMICS SENSOR SUPPLY VOLTAGE LOW or DTC C2115–DYNAMICS SENSOR SUPPLY VOLTAGE HIGH before diagnosing this DTC.
Turn 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.
WARNING: 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 20 km/hr (6 and 12 m.p.h.).
Park the vehicle.
With the scan tool, read ABS DTCs.
Does this DTC reset?
Yes
- Go To 2
No
- The 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. CHECK THE DYNAMICS SENSOR INSTALLATION
NOTE: Dynamics Sensor installation and mounting bolt torque is crucial for proper operation.
Turn the ignition off.
Check the Dynamics Sensor for damaged, modified, and bent mounting brackets.
Check the Dynamics Sensor mounting bolts for a loose or over tightened condition.
Were any problems found?
Yes
- Repair as necessary.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
- Go To 3
3. INSPECT RELATED WIRING HARNESS, TERMINALS, & CONNECTORS
Visually 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?
Yes
- Repair as necessary.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
- Replace the Dynamics Sensor in accordance with the Service Information.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
