CAUTION:
When using circuit tester to measure voltage for inspection, be sure not to extend forcibly any con-
nector terminals.
Fail-Safe
INFOID:0000000011278305
If any malfunction occurs in AWD electrical system, and control unit detects the malfunction, AWD warning on
information display (combination meter) is displayed to indicate system malfunction. And then AWD control
unit controls becomes the fail-safe mode depending on DTC.
Protection Function
INFOID:0000000011278306
AWD system activates its protection function (shuts down AWD system temporarily) if AWD system detects
high load continuously or the front wheel tire size differs from the rear tire size. (AWD system is automatically
restored if AWD system no longer detects any overload or the tire size difference is eliminated.)
NOTE:
• If the AWD warning displays during driving but remains not displayed after the engine is restarted, the syste-
mis normal. If it again displays 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.
