SYSTEM DESCRIPTION
On receiving a reverse signal from the park/neutral position switch assembly, the ECM sends the reverse signal to the main body ECU (driver side junction block assembly) via CAN communication. When receiving the reverse signal, the main body ECU (driver side junction block assembly) sends the reverse request signal to each outer mirror control ECU. Each outer mirror control ECU then performs control in response to the reverse signal.
Tech Tips
The reverse shift-linked function will not activate when the mirror select switch is in the neutral position (off).
