SPECIAL FUNCTION REFERENCE
| Item No. | Display on scan tool | Check items | Test content | Normal conditions |
|---|---|---|---|---|
| 1 | ACD air bleeding | Air bleeding < ACD > | According to the steering angle of steering wheel, energize the proportioning valve, and operate the proportioning valve for 5 minutes. | No air comes out from the bleeder screw established to the transfer. |
| 2 | AYC air bleeding | Air bleeding < AYC > | According to the steering angle of steering wheel, energize the proportioning valve, and operate the direction valve for 5 minutes. | No air comes out from the bleeder screw established to the torque transfer differential. |
| 3 | Oil level check | Oil level check | Operate the direction valve to left and right for 20 seconds. | Oil level of reservoir tank is adequate. |
| 4 | Motor drive | Electric pump operation | Operate the electric pump for 3 seconds. | Operating sound of the electric pump can be heard. |
| 5 | ACD operation check | ACD operation check | Operate the proportioning valve < ACD >, and supply the maximum hydraulic pressure to the multiplate clutch. | The tight corner braking phenomenon occurs. |
| 6 | AYC operation check (left) | Clutch operation check < left side > | Operate the direction valve, and supply the maximum hydraulic pressure to the left clutch. | With the wheels lifted, a speed difference is generated between left and right rear wheels. |
| 7 | AYC operation check (right) | Clutch operation check < right side > | Operate the direction valve, and supply the maximum hydraulic pressure to the right clutch. | With the wheels lifted, a speed difference is generated between left and right rear wheels. |
| 8 | Control OFF | Control OFF | Turn OFF the electric pump relay, and turn OFF the ACD and AYC control. | With the actual driving of vehicle, there is a difference between when the control is ON and OFF. |
- The actuator test can be performed only when all the following conditions are satisfied.
- Every wheel speed sensor input is 20 km/h or less.
- No system malfunction is detected.
- The steering angle of steering wheel is within ±30° from the neutral position.
- With the actuator test, when any of the conditions below is met, the forced activation will be canceled.
- Any of the wheel speed sensors detects an input of 20 km/h or more (excluding item No. 08 "Control OFF").
- A system malfunction is detected.
- The forced activation time has elapsed.
- Scan tool is removed.
- Scan tool clear key is operated.
