INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
1.READ VALUE USING INTELLIGENT TESTER (IG POWER SOURCE VOLTAGE)

  1. Turn the ignition switch off.

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the intelligent tester on.

  1. Enter the following menus: Chassis / KDSS / Data List.

  1. Select the item below in the Data List, and read the value displayed on the intelligent tester.
