Toyota RAV4 Service Manual: Test mode procedure

1. Test mode check

Hint:

• When entering the test mode, the tire pressure warning ecu sets all the test dtcs first. After completing the test mode for each inspection item, the dtcs that are determined normal by the tire pressure warning ecu will be erased.

  The dtcs for other inspection items may not be erased when only a certain signal is inspected.

• When the test mode returns back to the normal mode, all the test dtcs will be erased.

1. Make sure that the ignition switch is off.
2. Connect the intelligent tester (with can vim) to the dlc3.
