C2204-DYNAMICS SENSOR INTERNAL

For a complete wiring diagram, refer to the Wiring Information.

NOTE: The Electronic Stability Control (ESC) may also be referred to as Electronic Stability Program (ESP) depending on the vehicle model year and configuration. Certain components may also reference ESP, ESC, or use the traction control symbol.

- When Monitored:
Continuously, with ignition on, until vehicle speed exceeds 20 km/h (12.4 mph) for the first time, but not if the sensor voltage is out of range.

Or, during diagnostic mode.

Or, if the monitoring was inhibited by a corresponding diagnostics command.

Or, if the vehicle speed has exceeded 20 km/h (12.4 mph) during the actual ignition cycle.

Or, if at least one over spinning wheel is detected.

Or, if one of the control functions is active.

- Set Condition:
Internal problem with Dynamics Sensor.





1. VERIFY DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE
1. Turn the ignition on.
2. Using the scan tool, read and record ABS DTCs.
3. Using the scan tool, read and record Environmental Data (EV Data).
4. Using the scan tool, erase ABS DTCs.
5. Cycle the ignition switch.

WARNING: Make sure brake capability is available before road testing.

6. 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 mph).
7. Park the vehicle.
8. Using the scan tool, read ABS DTCs.

Does this DTC reset?

Yes

- Go To 2

No

- Perform the ABS Intermittent Condition diagnostic procedure ABS Intermittent Condition Test.

2. CHECK THE DYNAMICS SENSOR INSTALLATION

NOTE: Dynamics Sensor installation and mounting bolt torque is crucial for proper operation.

1. Turn the ignition off.
2. Check the Dynamics Sensor for damaged, modified, and bent mounting brackets.
3. Check the Dynamics Sensor mounting bolts for a loose or over tightened condition.

Were any problems found?

Yes

- Repair as necessary.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

No

- Replace the Dynamics Sensor.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.
