STEP 4. Check for the tight corner braking phenomenon occurrence during driving on a flat road
(1) Execute "Test" (item No. 1 Control OFF) on scan tool (M.U.T.-IIISE) special function.
(2) Operate the drive-mode selector to switch the drive mode to AUTO.
(3) Turn the steering wheel on a flat road clockwise or counterclockwise 360° or more.
(4) Move the selector lever to D range (1st gear) to start the vehicle slowly.
(5) The vehicle should hesitate to move forwards and a tight corner braking phenomenon should occur.
Does the tight corner braking phenomenon occur?
: Measure the coil current when the tight corner braking occurs. If the coil current measures 0 A, replace the transfer assembly (Refer to ) or electronic control coupling (Refer to ). Then go to Step 5. : Measure the coil current when the tight corner braking occurs. If the coil current is other than 0 A, go to Step 5. Go to Step 5.
