Automatic Transmission
The transmission range switch (245) is connected to TCM (502). When the selector lever is shifted to "R", RCM (502) receives information on the current selector position. TCM (502) sends the bus message "Automatic selector lever position R". If the ignition is on, REC (701) will feed B+ on pin 1 (T-C) and pin 11 (T-B) to pin 1 of the left or right reversing light (32/418HL or 32/418HR, respectively). Both light clusters (418HL/HR), in which the reversing lamps are located, are connected to ground on pin 2.
Reversing light activation is delayed 320 ms so the light does not flash when the gear selector is shifted from "P" to "D" or the like.
IMPORTANT:
When changing a bulb, use one with the right output otherwise the components could be damaged.
