Circuit Description

WARNING: This page is about a different car, the 2004 Lexus SC 430. However, it is still accessible from the selected car via links, so may be relevant.

While a switch signal of the power retraction mirrors is transmitted to the driver's and passenger's door ECU from the driver side junction block, the ACC signal is transmitted to the driver's and passenger's door ECU from the theft deterrent ECU as well. This time the power retraction mirrors do the retracting or returning operation.

NOTE: The power mirror control system has a function with large-scale body multiplex communication. First of all, inspect the communication function according to HOW TO PROCEED WITH TROUBLESHOOTING, and check that no malfunction exists in the communication system. Then proceed with the troubleshooting.
