LONGITUDINAL ACCELERATION SENSOR ERROR

The diagnostic equipment signals the following error: "C1335 - Longitudinal acceleration sensor"

This error is signalled if the sensor output voltage is below 0.3 V or above 4.7 V or if the yaw sensor supply voltage is more than 5.3 V or less than 4.7 V or if the value sent by the sensor is not plausible. This means that there is an open circuit or short circuit (positive or earth) for the sensor or the wiring, that the sensor is mechanically damaged or that the reading circuit is damaged.

1ELECTRICAL CHECKSAll OKProblems encounteredOperation

Check that the longitudinal acceleration sensor supply voltage is between 4.7 and 5.3 V

Check that the electrical connections between the acceleration sensor and the ABS control unit are correctMove on to Step 3 1
  • Wiring faulty
  • Sensor not correctly fastened
  • Renew the wiring and move on to Step 3
  • Restore the correct fastening for the sensor and move on to Step 3
3CHECK ON CORRECT OPERATIONAll OKProblems encounteredOperation

Delete the errors using the diagnostic equipment.

Carry out a road test
