ACD Mode Indicator Light
All ACD mode indicator lights turn on as a self-check for approx. 1.5 seconds after the ignition switch is turned to the ON position. Every time the ACD mode changeover switch is pressed, each ACD mode indicator light (TARMAC, GRAVEL, SNOW) turns on alternately.
When the ACD has a malfunction, all mode indicator lights turn on (until the ignition switch is turned to the OFF position*).
NOTE:
*: When the AWD-ECU determines that the malfunction has been resolved, it may resume normal ACD indicator light operation.
