Inspection steps

CAUTION: Always perform a steering zero point calibration after replacing the steering column assembly or power steering computer assembly. (Refer to WORK SUPPORT )

Check the connector connection
1. Check the connection state of motor rotation angle sensor connector z2.
  Criteria: The motor rotation angle sensor connector is properly connected to the power steering computer assembly.

  NG: Connect it securely
  
  OK: Go to Next Step

Read the SSM3 data (motor rotation angle)

Use the SSM3 to check the [Motor Rotation Angle]. (Refer to [CURRENT DATA DISPLAY & SAVE] )

SSM3 SCREEN: [POWER STEERING] →[CURRENT DATA DISPLAY & SAVE]

Item name	Description/display range	Normal value	Remark s
Motor rotation angle	Indicates the motor rotation angle. Display range: 0.000 - 360.000 deg	Varies between 0 and 360 deg: During engine start and steering operation	-

Criteria: During engine start and steering operation, this varies between 0 - 360 deg.

NG: Go to Step 3.

OK: Replace the power steering computer assembly (Refer to REMOVAL )

Inspect the steering column assembly (motor rotation angle sensor)

Disconnect the motor rotation angle sensor connector z2 from the power steering computer assembly.

Measure the resistance of the vehicle side connector.

RESISTANCE

Inspection terminals	Inspection conditions	Standard value
z2-5(RZV) - z2-7(RZG)	Always (23°C)	27.6 - 41.4Ω
z2-14(RZSN) - z2-7(RZG)	Always (23°C)	75.2 - 112.8Ω
z2-13(RZCS) - z2-7(RZG)	Always (23°C)	73.6 - 110.4Ω
