Self-diagnosis of the ABS/EDL for four-wheel drive vehicles with Haldex coupling |
Fault table for the ABS/EDL of four-wheel drive vehicles with Haldex coupling → Chapter |
Check longitudinal acceleration sender -G251- → Chapter |
Switch off longitudinal acceleration sender -G251- → Chapter |
Null balance of the longitudinal acceleration sender -G251- → Chapter |
The self-diagnosis for four-wheel drive vehicles with Haldex coupling is almost identical for vehicles with ABS/EDL. |
Note Only the differences to the „normal“ ABS/EDL system are described in the self-diagnosis. |
Characteristic feature of four-wheel drive vehicles with the Haldex coupling |
A longitudinal acceleration sender is positioned in the ABS system -G251-. |
The longitudinal acceleration sender must be switched off for checking the brake system on a roller type test stand -G251- → Chapter, initiate basic setting, display group number 040. |
The reactivation of the longitudinal acceleration sender -G251- is performed by switching the ignition off and on once. |
All four-wheel drive vehicles with Haldex coupling are fitted with the EDL (electronic differential lock). |
