C1210-G SENSOR INPUT CIRCUIT PERFORMANCE
For a complete wiring diagram Refer to Section 8W.
- When Monitored:
Continuously, with ignition on, until vehicle speed exceeds 20 km/h (12.4 m.p.h.) 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.
- Set Condition:
If the measured acceleration signal is higher than 0.8 g for longer than the specified detection time.

Diagnostic Test
1. CHECK FOR A DTC C1210–G SENSOR INPUT CIRCUIT PERFORMANCENOTE: This DTC must be active for the results of this test to be valid.
Turn the ignition on.
With the scan tool, read and record DTCs.
With the scan tool, read and record Freeze Frame information.
With the scan tool, erase DTCs.
Cycle the ignition switch from off to on.
With the scan tool, read and record DTCs.
Does the scan tool display: C1210–G SENSOR INPUT CIRCUIT PERFORMANCE?
Yes
- Go To 2
No
- Refer to the INTERMITTENT CONDITION diagnostic procedure.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
2. CHECK THE TERMINALS/CONNECTORS/WIRING HARNESS FOR DAMAGE
Check the Steering Angle Sensor installation.
Check all related wiring for bruised, chafed, pierced, or partially broken wires.
Check all related connectors for broken, bent, pushed out, or corroded terminals.
Were any problems found?
Yes
- Repair as necessary.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
- Go To 3
3. (G4) DYNAMICS SENSOR SUPPLY HIGH RESISTANCE
Turn the ignition off.
Disconnect the Dynamics Sensor harness connector.
Disconnect the Anti-Lock Brakes Module harness connector.
Measure the resistance of the (G4) Dynamics Sensor Supply circuit between the Dynamics Sensor harness connector and the Anti-Lock Brakes Module harness connector.
Is the resistance below 5.0 ohms?
Yes
- Go To 4
No
- Repair the (G4) Dynamics Sensor Supply circuit for high resistance.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
4. (G94) GROUND CIRCUIT HIGH RESISTANCE
Turn the ignition off.
Measure the resistance between the (G94) Ground circuit and ground.
Is the resistance below 5.0 ohms?
Yes
- Go To 5
No
- Repair the (G94) Ground circuit for high resistance.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
5. 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
- Replace the Dynamics Sensor in accordance with the Service Information.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
