Troubleshooting BCM-C006A17
Checking the wiring
- Ignition off
- Connect a breakout box.
Check the cables for short circuit to supply voltage.
Measure between:
- AYC sensor connector terminal #3 and brake control module (BCM) terminal #6 (#A6).
- AYC sensor connector terminal #5 and brake control module (BCM) terminal #39 (#A39).
Other information
- Signal specification, brake control module (BCM) with DSTC (dynamic stability and traction control), B8444S, B6324S Signal Specification
- Active yaw control sensor, replacing Service and Repair
- Checking wiring and terminals Checking Wiring and Terminals
Was a malfunction detected?
Yes - Verification
No - Checking the control module
-------------------------------------------------
Checking the control module
- Ignition off
- Breakout box connected to brake control module (BCM).
- AYC sensor connector unplugged.
- Start the engine.
- Read off the voltage feed to the brake control module (BCM).
Check the voltage feed to the AYC sensor by connecting a voltmeter between brake control module (BCM) terminals #6 (#A6) and #39 (#A39).
Check that voltage is about the same as the read value of the brake control module (BCM).
If the voltage feed to the AYC sensor is OK, replace the AYC sensor.
If the voltage to the brake control module (BCM) is too high, check the charging system.
Remedy as necessary.

Hint: After carrying out the repair, check that the malfunction has been remedied.
- Ignition off
- Reconnect the connectors, components, etc.
- Test-drive the vehicle according to Test Drive Form (DSTC (dynamic stability and traction control) /brake control module), description Test Drive Form (DSTC (Dynamic Stability and Traction Control)/Brake Control Module), Description.
Note! Do not turn off the ignition between test-driving and reading out diagnostic trouble codes. This is to obtain the correct status of the diagnostic trouble codes.
Then read out the diagnostic trouble code's status without turning off the ignition after the test-drive.
Is the status of the diagnostic trouble code intermittent?
Yes - Troubleshooting procedure complete
No - Troubleshooting information

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.
Do you want to exit fault-tracing?
Yes - Exit Fault-tracing
No - Attempt New Test

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.
