C2204-DYNAMICS SENSOR INTERNAL
For a complete wiring diagram Refer to Section 8W.
- 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:
If the Anti-Lock Brakes Module detects that the Lateral Sensor signal is out of range.

Diagnostic Test
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.
WARNING: To avoid personal injury or death, check 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/h (6 and 12 mph).
Park the vehicle.
With the scan tool, read ABS DTCs.
Does this DTC reset?
Yes
- Go To 2
No
- Perform the ABS Intermittent Condition diagnostic procedure in this Section.
- 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. CHECK DYNAMICS SENSOR OUTPUT
CAUTION: All previously removed connectors must be connected before test driving the vehicle, to avoid personal injury or death,
Connect all previously disconnected components and connectors.
WARNING: To avoid personal injury or death, check brake capability is available before road testing.
Monitor Dynamics Sensor operation while an assistant drives the vehicle.
Is Lateral Sensor output between 0.02 G to 0.16 G and Yaw Sensor output between 1.30° to 5.70°
Yes
- Replace the Anti-Lock Brakes Module in accordance with the Service Information.
- 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).
