2.PRECAUTION WHEN REPLACING MAIN BODY ECU

  1. As the door control battery is installed between the vehicle battery and main body ECU, first perform the inspections in On-Vehicle Inspection to confirm that there are no malfunctions in the power source circuit for the main body ECU before performing this troubleshooting procedure (Click here).

  2. If the MPX-B NO.1 fuse (the main power source fuse of the cowl side junction block LH) is removed with the door control battery charged, power will be supplied to the main body ECU from the door control battery for up to 30 minutes. At this time, the main body ECU will be able to function with the MPX-B NO.1 fuse (the main power source fuse of the cowl side junction block LH) removed.
