Checking the connectors
- Ignition off
- Check the connectors of the brake control module (BCM) and the pressure build-up valve/pedal pressure sensor for contact resistance and oxidation.
- Reinstall the components, reconnect the connectors etc.
- Ignition on
- Use the Activation function to activate the pressure build-up valve.
A mechanical pumping sound should be audible from the engine compartment and the pedal should move slightly.
Other information
- For removal of the control module connectors: Connecting the breakout box, brake control module (BCM) Connecting the Breakout Box, Brake Control Module (BCM)
- Checking wiring and terminals Checking Wiring And Terminals
Was the function OK?
Yes - Fault Found
No - Checking wiring and sensors
-------------------------------------------------
Checking wiring and sensors
Check the cables between the pressure build-up valve:
- #3 and brake control module (BCM) #31 (#A31)
- #4 and brake control module (BCM) #17 (#A17)
check for an open-circuit, a short-circuit to ground and a short-circuit to supply voltage.
Hint: Check the pressure build-up valve by, with the ignition off and the breakout box connected, reading the resistance between terminals #17 and #31 on the breakout box. Resistance must be approximately 3ohms.
Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reinstall the components, reconnect the connectors etc.
- Ignition on
- Use the Activation function to activate the pressure build-up valve.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
