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.

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.

Toyota Invests Big In Batteries

With an $8 billion investment, Toyota plans for 10 new BEV/PHEV battery lines by 2030.

Toyota invested nearly $8 billion which will add approximately 3,000 jobs at Toyota Battery Manufacturing North Carolina (TBMNC). This brings total investment to approximately $13.9 billion and job creation to more than 5,000, Toyota said, further supporting Toyota’s multi-pathway approach to global vehicle electrification.

Toyota said this investment adds capacity to support battery electric vehicles (BEV’s) and plug-in hybrid electric vehicles (PHEV’s). An additional eight BEV/PHEV battery production lines will be added to the two previously announced, for a total of 10 BEV/PHEV battery lines. In addition, as originally announced, the plant will also have four battery lines for Hybrid Electric Vehicles (HEVs). Production will be increased in a phased approach, with line launches planned through 2030 to reach a total production of more than 30 GWh annually.
