DTC

C1516

Torque Sensor Zero Point Adjustment Incomplete

DESCRIPTION

This DTC does not indicate a malfunction. The power steering ECU (rack and pinion power steering gear assembly) stores this DTC when it determines that torque sensor zero point calibration has not completed.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Warning Indicate	Return-to-normal Condition	Note
C1516	Torque Sensor Zero Point Adjustment Incomplete	Torque sensor zero point calibration is incomplete due to the steering wheel being touched during calibration.	Torque sensor zero point calibration	EPS warning light: Comes on	The DTC is cleared	There is no malfunction if this DTC is not output again after clearing the DTC and torque sensor calibration value, and performing zero point calibration.

CAUTION / NOTICE / HINT

NOTICE:

If the rack and pinion power steering gear assembly has been replaced, perform assist map writing and torque sensor zero point calibration.

PROCEDURE

1.	REPLACE CHECK FOR DTC

(a) Clear the DTCs. (Step 1)

Chassis > EMPS > Clear DTCs

(b) Calibrate the torque sensor zero point. (Step 2)

Chassis > EMPS > Utility

Tester Display
Torque Sensor Adjustment

Chassis > EMPS > Trouble Codes

HINT:

If DTCs are output, perform steps (1) to (3) two more times.

Result	Proceed to
DTCs are still output after performing steering zero point calibration 3 times.	A
Normal system code is output.	B

REPLACE RACK AND PINION POWER STEERING GEAR ASSEMBLY
