PRECAUTIONS FOR DIAGNOSIS

With the TC-SST assembly, the IG shutoff delay system is adopted to improve the engine starting performance.
When the ignition switch is turned OFF, the IG shutoff delay system release the gear engagement in preparation for the next engine starting. This is a system to delay the engine stop for approximately 1 second, and the delay is not a malfunction.









If the gear is not in the reverse position, the R range indicator of the multi information display (a) and the R range indicator of the floor console panel (b) flash. This is a warning to the driver, and is not a malfunction.
In this case, return the shift lever to the N range, and move it to the R range again. If the flashing of each R range indicator changes to normal illumination, it indicates that the gear is in reverse position.
