Inspection Procedure

NOTE:

Start the inspection from step 1 in case of using the hand-held tester and start from step 3 in case of not using the hand-held tester.

Check output value of the steering angle sensor .
1. Connect the hand-held tester to the DLC3.
2. Turn the ignition switch ON and push the hand-held tester main switch ON.
3. Select the DATALIST mode on the hand-held tester.
Check that the steering wheel turning angle value of the steering angle sensor displayed on the hand-held tester is appropriate when turning the steering wheel.

OK: Steering wheel turning angle value must be appropriate .
1. OK: Go to step 5 .
2. NG: Go to next step .
Check the steering angle sensor zero point .
1. Connect the hand-held tester to the DLC3.
2. Turn the ignition switch ON and push the hand-held tester main switch ON.
3. Select the DATALIST mode on the hand-held tester.
Check whether steering angle sensor value is nearly equal to 0 degree when steering wheel is adjusted to neutral.
1. OK: Go to next step .
2. NG: Calibrate the steering angle sensor zero point. See step 3 under PRE-CHECK .
Check the installation condition of steering angle sensor .
1. OK: Go to next step .
2. NG: Repair or replace steering angle sensor .
Check for open and short circuit in harness and connector between steering angle sensor, Translate ECU and Skid Control ECU. See HOW TO USE THE DIAGNOSTIC CHART AND INSPECTION PROCEDURE .
1. OK: Go to next step .
2. NG: Repair or replace harness or connector .
Calibrate the steering angle sensor. See 3 under PRE-CHECK .
1. OK: Go to next step .
2. NG: Replace steering angle sensor .
Is DTC still output?
Check DTC. See b- d under PRE-CHECK.
1. YES: Go to next step .
2. NO: No problem .
Replace the ECU and check whether or not the trouble occurs again .
1. YES: Replace steering angle sensor .
2. NO: Check and replace Skid Control ECU .
