STEERING 32 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.
