If the result is not as specified, the dlc3 may have a malfunction. Repair or replace the harness and connector.

Hint:

Connect the cable of the intelligent tester (with can vim) to the dlc3, turn the ignition switch on and attempt to use the tester. If the display indicates that a communication error has occurred, there is a problem wither with the vehicle or with the tester.

  1. The tire pressure warning light blinks when there is a malfunction in the tire pressure warning system.

Notice:

When the malfunction has been corrected, the tire pressure warning light does not turn on.

  1. Dtcs (normal mode)
  1. Dtcs are memorized in the tire pressure warning ecu. These dtcs can be read by checking the blinks of the tire pressure warning light or by using the intelligent tester (see page tw-20).
  1. Test mode
  1. By switching from normal mode to test mode (input signal check), you can inspect the tire pressure monitor receiver, each tire pressure warning valve and transmitter and vehicle speed sensor (see page tw-12).
