PID/DATA MONITOR TABLE [ELECTRIC POWER STEERING (EPS)]

• If the PID/data monitor value “STR_ANG” is inspected, perform the following procedure before inspecting.

1. Switch the ignition to OFF, and maintain this condition for approx. 3 s.

2. Set the vehicle wheels in the straight-ahead position.

3. Switch the ignition ON (engine off or on).
