STEERING

ANGLE

CALIBRATION

PROCEDURE

It is necessary to calibrate and initialize the EPAS

ECU in order to correctly startup the steering

system.

Calibration: When calibr

ating, the steering gear’s/

front axle’s straight

-ahead position is compared

with the straight-ahead position of the steering

column’s internal steering angle. For Calibrating

the EPAS ECU,

use either Mando Test Man or

diagnostic tester.

Initialization and teach-in software end stops: This

is done by steering past the index position on the

internal torque sensor (the steering column) in the

straight-ahead position, when steering left and

steering right. At the same time, the software end

stops are taught i

n. After initializing, “Active reset”

& “software end stop” functions will be active

NOTE:



While doing the steering angle calibration and

initialization process, Please follow the

instruction which are displaying on Diagnostics

tool window.



If required, before doing steering angle

calibration and initialization process, operator

needs to do first rack centralization followed by

wheel alignment on vehicle as per

specification.



If steering angle calibration process is not

completed, than EPAS warning lamp will glow

in IPC.
