Tech Tip: Mercedes-Benz Brake Pedal Switch Adjustment

Fault codes C1200, C1201 or C1202 may be set in the ESP control module in the event of a misadjusted brake pedal switch on the following models: 129,170, 202, 208, 210, 215 and 220. Before adjusting the brake pedal switch, use DAS and check the switch for proper voltage supply. If replacing the switch, ensure that the correct part number is installed based on the vehicle model.

Service Procedure:
1. Remove the stop lamp switch and pull out the self-adjusting tappet.

2. Re-install the stop lamp switch and place a spacer with a thickness of 1.5 mm between the stop lamp switch tappet and the stop on the brake pedal.

3. Release the brake pedal (the stop lamp switch will adjust itself automatically) and, at the same time, pull back the brake pedal by hand with slightly more force than the force of the return spring.

4. When the setting process has been completed, the spacer must be removed.

Note: The brake pedal switch adjustment process will affect the BAS system. The BAS release switch fault may be stored as a result of the plausibility test between the BAS release witch and the brake pedal switch if the brake pedal switch is incorrectly adjusted.

Choosing the Right Power Steering Fluid

Learn what power steering fluid is, why it’s crucial for your customers vehicle, and how to choose the right type.

So what is power steering fluid? Power steering fluid is hydraulic oil for the most part, with certain additives that are tuned for the automotive applications, but it is hydraulic fluid. In other words, you have a pump that creates pressure and that force is changed into energy at a steering rack by turning the wheels or extending the tie rods in either direction. What else is hydraulic on the vehicle? The automatic transmission. This is why some vehicles will actually specify transmission fluid to be used inside the power steering system, but there are exceptions. Certain vehicles out there, mostly Asian, have their own formulation of power steering fluid. So it is absolutely critical that you match the power steering fluid with the application. Some may use a different weight of oil, and if you use the wrong power steering fluid, it can change the feel of the steering, but most of all, it can damage the pump and the rack on the vehicle.
