C1210

C1210-G SENSOR INPUT CIRCUIT PERFORMANCE





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
Once per loop, but not during active test function of acceleration sensor if the sensor voltage is out of range.

- Set Condition:
Longitudinal acceleration sensor signal is out of range.





Diagnostic Test

1. CHECK FOR A DTC C1210-G SENSOR INPUT CIRCUIT PERFORMANCE
NOTE: 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

- 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. ABS Intermittent Condition Test

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. ABS Verification Test.

No

- Go to 3

3. (G4) DYNAMICS SENSOR SUPPLY HIGH RESISTANCE




Turn the ignition off.
Disconnect the Dynamics Sensor harness connector.
Turn the ignition on.
Measure the voltage of the (G4) Dynamics Sensor Supply circuit at the Dynamics Sensor harness connector.
Is the voltage above 10 volts?

Yes

- Go to 4

No

- Repair the (G4) Dynamics Sensor Supply circuit for high resistance.
- Perform ABS VERIFICATION TEST. ABS Verification Test.

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. ABS Verification Test.

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. ABS Verification Test.

No

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