STEERING ANGLE SENSOR ERROR

1.1, 1.2 8v

The diagnostic equipment signals the following errors: "C1117 - Steering Angle Sensor invalid" and "C1517 - Steering Angle sensor: compensation error"

1.3 JTD 16v

The diagnostic equipment signals the following errors: "C1117 - Steering Angle Sensor invalid" and "C1517 - Steering Angle sensor: compensation error"

1.1, 1.2 8v

These errors are signalled if there is a short circuit at the CAN (supply or earth), if the sensor is damaged or not correctly fitted.

1.3 JTD 16v

These errors are signalled if there is a short circuit at the CAN (supply or earth), if the sensor is damaged or not correctly fitted.

1.1, 1.2 8v

1	CHECKS USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Connect the diagnostic equipment and check the operation of the steering angle sensor. To do this enter the PARAMETERS ambient and display the STEERING ANGLE parameter: the values should increase when the steering wheel is turned in a clockwise direction (to the right) and decrease when it is turned in the opposite direction	Move on to Step 5	Failed or irregular operation of the steering angle sensor:	Move on to Step 2 1
3	CAN CHECK	All OK	Problems encountered	Operation
	Check correct CAN network impedence See Test 5505OA CAN LINE C CHECK	Move on to Step 5 1	Motor control unit resistance non-compliant Body control unit resistance non-compliant Faults in CAN network connections	Replace engine control unit Op. 1056B82 INJECTION/IGNITION SYSTEM E.C.U. (ONE) - R + R Replace Body Op. 5505A32 BODY COMPUTER - R R Restore correct connections and move on to Step 4
4	ELECTRICAL CHECKS	All OK	Problems encountered	Operation
	Check the electric steering supply voltage Check the wiring from the NFR to the NGE See E7045 ELECTRIC STEERING	Move on to Step 5 1	Supply not correct Wiring faulty	Restore the correct power supply and replace the faulty components if necessary Renew the wiring and move on to Step 5
5	CHECK ON CORRECT OPERATION	All OK	Problems encountered	Operation
	Delete the errors using the diagnostic equipment. Carry out a road test See Test 3350EB STEERING ANGLE SENSOR OPERATION CHECK to ensure that the control unit checks whether there are any errors still present. Return to the workshop and check that the fault is no longer present using the diagnostic equipment	End of diagnosis	The fault persists	Move on to Step 2

2	WHEEL TOE IN CHECK	All OK	Problems encountered	Operation
	Check the toe in of the front and rear wheels	Move on to Step 3 1	The vehicle has lost its toe in	Restore the toe in and move on to Step 5
3	CAN CHECK	All OK	Problems encountered	Operation
	Check correct CAN network impedence See Test 5505OA CAN LINE C CHECK	Move on to Step 5 1	Motor control unit resistance non-compliant Body control unit resistance non-compliant Faults in CAN network connections	Replace engine control unit Op. 1060G80 DS ELECTRIC INJECTION CONTROL UNIT - R R Replace Body Op. 5505A32 BODY COMPUTER - R R Restore correct connections and move on to Step 4
