C1210–G SENSOR INPUT CIRCUIT PERFORMANCE





For a complete wiring diagram Refer to Section 8W.


  • 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.


Possible Causes
  
WIRING HARNESS, TERMINAL, CONNECTOR DAMAGE
  
(G4) DYNAMICS SENSOR SUPPLY HIGH RESISTANCE
  
(G94) GROUND CIRCUIT HIGH RESISTANCE
  
DYNAMICS SENSOR INSTALLATION
  
DYNAMICS SENSOR
  
ANTI-LOCK BRAKES MODULE
  



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.









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. (Refer to 5 - BRAKES - DIAGNOSIS AND TESTING)

2.CHECK THE TERMINALS/CONNECTORS/WIRING HARNESS FOR DAMAGE





Were any problems found?

Yes


No
  • Go To 3

3.(G4) DYNAMICS SENSOR SUPPLY HIGH RESISTANCE






Is the voltage above 10 volts?

Yes
  • Go To 4


No

4.(G94) GROUND CIRCUIT HIGH RESISTANCE




Is the resistance below 5.0 ohms?

Yes
  • Go To 5


No

5.CHECK THE DYNAMICS SENSOR INSTALLATION

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






Were any problems found?

Yes


No
