Inspection procedure
- Perform active test by intelligent tester
- Connect the intelligent tester (with can vim) to the
dlc3.
- Turn the ignition switch to the on position and press the
intelligent tester main switch on.
- Select the item below in the active test and then
check the relay operation.
