ELECTRONIC CONTROL COUPLING (CENTRE) OPERATION CHECK <VEHICLES WITH S-AWC>

2.Mark the front and rear tyres for easy identification of tyre rotation. 3.Adjust the parking brake lever to the normal conditions (Refer to GROUP 36 - On-vehicle Service, Parking Brake Lever Stroke Check and Adjustment). 4.Pull the parking brake lever by two notches. note Applying the parking brake slightly prevents the drive force transferring to the rear wheels by a friction in the electronic control coupling. If it is checked without the parking brake apply, the drive force is transferred to the rear wheels by a friction in the electronic control coupling. 5.Turn the ignition switch to "ON" position and keep the steering wheel in the neutral position. Then carry out the special function test No. 4 "Control OFF". 6.Start the engine, and move the selector lever into D position. 7.Drive the vehicle straight with vehicle speed of less than 20 km/h. caution In order to protect the 4WD drive system parts, check must be finished within 1 minute in total. Check if the rear wheels do not rotate. 8.Stop the engine. 9.Turn the ignition switch to "ON" position and carry out the special function test No. 6 "Centre coupling operation check". note The limit time of "Centre coupling operation check" is 1 minute. 10.Start the engine again, and move the selector lever into D position. 11.Drive the vehicle straight with vehicle speed of less than 20 km/h. caution In order to protect the 4WD drive system parts, check must be finished within 1 minute in total. Check if the rear wheels rotate. 12.Carry out the check above. Then when the tyre operates as mentioned, it is judged that the AWC-ECU control and electronic control coupling (Centre) are normal. If the tyre does not operate as mentioned, replace the electronic control coupling (Centre). (Refer to GROUP 27C, Electronic Control Coupling.)
