Test 1: Check component B37 (Accelerator pedal sensor).

1. Check component B37 (Accelerator pedal sensor).

Test 1.1: Check component B37 (Accelerator pedal sensor) using actual value.

Test 1.2: Check power supply of component B37 (Accelerator pedal sensor).

1.1. Check component B37 (Accelerator pedal sensor) using actual value.

Test sequence

- Switch on ignition.

Status of the relevant actual values:

- B37 (Pedal value sensor) Voltage 1:Warning! Communication with ECU required.

- B37 (Pedal value sensor) Voltage 2:Warning! Communication with ECU required.

Specified values

- Accelerator pedal position:Idle speed

- B37 (Accelerator pedal sensor)Signal1 : [0.2...0.5] V

- B37 (Accelerator pedal sensor)Signal2 : [0.1...0.5] V

- Accelerator pedal position:Kickdown

- B37 (Accelerator pedal sensor)Signal1 : [4.3...4.8] V

- B37 (Accelerator pedal sensor)Signal2 : [2.1...2.5] V

Question

- Are the actual values o.k.?

YES

The actual values are okay.End of test

NO

The actual values are not okay.Possible cause and remedy

- Check power supply of component B37 (Accelerator pedal sensor).

- Check lines from component N3/10 (ME-SFI [ME] control unit) to component B37 (Accelerator pedal sensor).

- B37 (Accelerator pedal sensor)

1.2. Check power supply of component B37 (Accelerator pedal sensor).
