Operation
Back-up lights (ATX)
1.When the selector lever is in the R position with the ignition switched ON (engine off or on), the TCM sends (1) an R position signal to the instrument cluster via CAN communication.
2.When the instrument cluster receives the R position signal, it sends (2) a back-up light on request signal to the BCM.
3.The BCM sends (3) the back-up light on request signal to the electrical supply unit (ESU) via LIN communication.
4.When the electrical supply unit (ESU) receives the back-up light on request signal, it turns the back-up light on (4).

Back-up lights (MTX)
1.When the shift lever is in the reverse position, the back-up light switch turns on (1).
2.When the back-up light switch is on with the ignition switched ON (engine off or on), the PCM detects (2) a back-up light switch on signal.
3.The PCM sends (3) the back-up light switch on signal to the instrument cluster via CAN communication.
4.When the instrument cluster receives the back-up light switch on signal, it sends (4) a back-up light on request signal to the BCM.
5.The BCM sends (5) the back-up light on request signal to the electrical supply unit (ESU) via LIN communication.
6.When the electrical supply unit (ESU) receives the back-up light on request signal, it turns the back-up light on (6).
