Technical Description (Comment)

It is suspected that the power supply circuit to the front-ECU is defective, or the wiring harness between the SWS monitor kit and the front-ECU or their connector(s) is damaged. If the battery power supply circuit to the ECU (terminal No.7 of the front- ECU) is damaged, also check the power supply circuit from the ignition switch (IG2) (terminal No.30 of the front-ECU), and repair if necessary.
