## for Preparation Click here

NOTICE:

  When removing parts, turn the ignition switch OFF.

HINT:

1. If an abnormality is not found when inspecting parts, inspect the ECU and ground points for poor contact.
2. If a malfunction code is displayed during the DTC check, check the circuit listed for that code. For details of each code, refer to the page number under the DTC in the chart below.
3. When 2 or more DTCs are detected, perform inspections on each circuit until the problem is identified.
