C0290 Code - EBCM Failed To Receive Serial Data From PCM

Quick Answer

The Powertrain Control Module (PCM) sends a state of health message to the Electronic Brake Control Module (EBCM) within 5.5 seconds after the modules are powered up. Common causes include Electronic Brake Control Module (EBCM) Calibration, Faulty Electronic Brake Control Module (EBCM), Electronic Brake Control Module (EBCM) harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about C0290 Code

1. What does OBDII code C0290 mean?

Code C0290 indicates that the Electronic Brake Control Module (EBCM) failed to receive serial data communication from the Powertrain Control Module (PCM).

2. What are the common symptoms of code C0290?

Common symptoms include the ABS warning light being illuminated, traction control issues, and intermittent or complete loss of ABS functionality.

3. What causes the EBCM to fail to receive data from the PCM?

The most common causes are wiring issues, such as damaged or corroded connectors, a failed EBCM, a malfunctioning PCM, or communication network faults.

4. Can a bad PCM cause code C0290?

Yes, a malfunctioning PCM can fail to send data to the EBCM, triggering code C0290.

5. How can I diagnose code C0290?

Start by inspecting the wiring and connectors between the EBCM and PCM for damage or corrosion. Use a scan tool to check for related communication codes and test the CAN (Controller Area Network) bus.

6. Is it safe to drive with code C0290?

Driving with code C0290 may compromise ABS and traction control functionality, which could lead to reduced safety in certain driving conditions.

7. How do I fix code C0290?

Repairs may include fixing damaged wiring or connectors, reprogramming or replacing the EBCM or PCM, and ensuring proper communication on the CAN bus.

8. Can a low battery voltage cause code C0290?

Yes, low battery voltage or a weak charging system can disrupt communication between the EBCM and PCM, potentially triggering this code.

9. Do I need to replace the EBCM to fix code C0290?

Not necessarily. The EBCM should only be replaced after confirming that the issue isn't caused by wiring, connectors, or the PCM.

10. Can a scan tool clear code C0290 after repairs?

Yes, after addressing the root cause, a scan tool can clear the code. However, the vehicle should be test-driven to ensure the issue is fully resolved.
