INSPECTION PROCEDURE

NOTICE:

HINT: Operating the ignition switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change.

1 CHECK OPEN IN CAN BUS WIRE (STEERING ANGLE SENSOR BRANCH WIRE)

  1. Turn the ignition switch off.
  2. Disconnect the steering angle sensor connector.
  3. Measure the resistance according to the value(s) in the table below.

Standard resistance

2 CHECK WIRE HARNESS (BAT, IG1, ESS)

  1. Measure the resistance according to the value(s) in the table below.

Standard resistance

  1. Measure the voltage according to the value(s) in the table below.
