Actuator Test Table
M.U.T-III can be used to forcibly activate the electronic control coupling and indicators (AWD indicator and LOCK indicator) in the combination meter according to the following items.
NOTE:
- If AWD-ECU is deactivated by the fail-safe function, no actuator test can be performed.
- As for the item No. 01, the chassis dynamometer is used to check the AWD torque. A simple AWD status check method, however, can be applied by checking whether a tight corner braking phenomenon appears during driving.
CAUTION:
When the item No. 01 is checked, the speed difference between front and rear wheels must be 5 km/h (3 mph) or lower. If the speed difference exceeds 5 km/h (3mph), AWD-ECU changes from the actuator test mode to the normal control mode.
