C123C - Dynamics Sensor Mounting/Installation Performance






For a complete wiring diagram, refer to.

• When Monitored: With vehicle speed more than 7 m.p.h. (11 km/h), but not if the sensor signal is invalid.

• Set Condition: If the anti lock brake module detects implausible Dynamics Sensor values.






Test Step 1 - Verify DTC Is Active

• 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 the ABS DTCs.

• With the scan tool, read and record the Environmental Data to help identify the conditions in which the DTC was set.

• With the scan tool, erase the 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 6 and 12 m.p.h. (10 and 20 km/h).

• Park the vehicle.

• With the scan tool, read the ABS DTCs.

Does this DTC reset?

Yes

• Go to Test Step 2 => [ Test Step 2 - Test the Dynamics Sensor Installation ]

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.

• Perform the ABS Intermittent Condition Test. Refer to => Non-DTC Based Diagnostics. ABS Intermittent Condition Test

Test Step 2 - Test the Dynamics Sensor Installation

• Dynamics sensor installation and mounting bolt torque is crucial for proper operation.

• Turn the ignition OFF.

• Test the dynamics sensor for damaged, modified and bent mounting brackets.

• Test 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 => Non-DTC
Based Diagnostics. ABS Verification Test

No

• Go to Test Step 3 => [ Test Step 3 - Inspect Related Wiring Harness, Terminals, and Connectors ]

Test Step 3 - Inspect Related Wiring Harness, Terminals, and 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 => Non-DTC
Based Diagnostics . ABS Verification Test

No

• Replace the dynamics sensor.

• Perform ABS Verification Test. Refer to => Non-DTC
