DESCRIPTION

NOTE: Light tight-corner braking symptom may occur depending on driving condition. This is not malfunction.

AWD SYSTEM : Fail-Safe

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.

DTC Vehicle condition
  • C1201
  • C1204
  • C1209
  • P1804
  • P1809
  • P18
AWD control changes to front-wheel drive immediately, then AWD control stops, and the vehicle becomes front-wheel drive.
  • C1203
  • C1210
  • P1808
  • P181D
  • U1000
  • U1010
AWD control changes to front-wheel drive gradually (rear-wheels still have some driving torque), then AWD control stops, and the vehicle becomes front-wheel drive
  • P181B
No impact to vehicle behavior.

AWD SYSTEM : Protection Function

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.)

DTC AWD warning (on information display) Error area and root cause Contents of protection function
Refer to DLN-16, "INFORMATION DISPLAY (COMBINATION METER) : AWD Warning". Rear final drive assembly in protection mode. It is not malfunction.

(Internal temperature rise of electronic controlled coupling)

Shuts down AWD system temporarily  (Front wheel drive)
Rear final drive assembly in protection mode. It is not malfunction.

(Internal temperature rise of electronic controlled coupling)

NOTE:

INFORMATION DISPLAY (COMBINATION METER)

INFORMATION DISPLAY (COMBINATION METER) : AWD Warning

DESIGN/PURPOSE

AWD warning is displayed when the AWD system has a malfunction. AWD warning indicates that the vehicle is in fail-safe mode or protection function mode.

Symbol Message Condition

AWD Error
See Owner’s Manual
AWD system malfunction.
AWD Error
See Owner’s Manual
Protection function is activated due to heavy load to electric controlled coupling. (AWD system is not malfunctioning and AWD system changes to rear wheel drive.)
Tire Size Incorrect
See Owner’s Manual
Large difference in diameter of front/rear tires.

  • Vehicle stopped
  •  Engine running
  •  No DTC detected
Change command current value to AWD solenoid, and then change driving mode. (Monitor value is normal if it is within approx. ±10% of command value.)
  •  Qu: Increase current value in increments of 0.2 A
  •  Qd: Decrease current value in increments of 0.2 A
  •  UP: Increase current value in increments of 0.02 A
  •  DOWN: Decrease current value in increments of 0.02 A
