| Checking function of Haldex coupling |
| –
| Drive front wheels of vehicle onto rolling road. |
Caution | Ensure area in front of vehicle is kept free. Carry out test with care to avoid damage. |
|
| –
| Engage 1st gear and slowly start driving. |
| l
| If the vehicle is not pushed off the rolling road at an engine speed of 1500 rpm, then the Haldex coupling is defective. |
Note! | t
| When the front wheels are driven whilst the rear wheels are stationary, the Haldex coupling will lock up. This means that the rear wheels are also driven. |
| t
| The Haldex coupling can accept differing speeds for a short period without locking up only with 1st gear engaged and engine speed slightly above idling speed. |
