Hydraulic pump for traction control -V156- and the sensor for brake pressure -G201-
The hydraulic pump for traction control -V156- and the sensor for brake pressure -G201- are located in the engine compartment on the left (in the direction of travel) underneath the ABS Hydraulic Unit -N55-.
The ABS Hydraulic Unit -N55- and ABS return flow pump -V39- are supported by the hydraulic pump for traction control -V156-. This ensures brake pressure is quickly increased in the brake cylinders at each wheel, as needed.
Do not remove any bolts from the individual components, such as the ABS Hydraulic Unit -N55- and the hydraulic pump for traction control -V156-. The hydraulic pump for traction control -V156- and the sensor for brake pressure -G201- comprise one unit and must always be replaced as a set.
The sensor for brake pressure -G201- measures the build up of brake fluid pressure in the brake system.
