Protection Function
system activates its protection function (shuts down system temporarily) if system detects high load continuously, the front wheel tire size differs from the rear tire size or the rear right wheel tire size differs from the rear left tire size. (system is automatically restored if system no longer detects any overload or the tire size difference is eliminated.)
| Detected DTC | Warning lamp | Possible cause | Vehicle condition |
|---|---|---|---|
| - | Quick blinking* 1 | Turning difference remains between front and rear wheels or between right and left rear wheels, resulting in an oil temperature rise in drive train related parts.
NOTE:
It is not malfunction. |
Shuts down system temporarily |
| - | Slow blinking* 2 | Malfunction in each tire or different tire diameter |
* 1: 2 times/second (blinking for approximately 1 minute and then turned OFF)
* 2: 1 time/2 seconds (continuing to blink until ignition switch is turned OFF)
NOTE:
- If the AWD warning lamp blinks slowly during driving but remains OFF after the engine is restarted, the system is normal. If it again blinks slowly after driving for some time, vehicle must be inspected.
- When there is a difference of revolution speed between the front and rear wheel the shift occasionally changes to direct 4-wheel driving conditions automatically. This is not a malfunction.
