OBD-II trouble code
C0292: EBCM Failed to Receive Serial Data From PCM
The ABS module (EBCM) stopped receiving the expected data messages from the engine/powertrain computer (PCM) over the vehicle's communication network. ABS and traction/stability control may be disabled, but base braking still works.

What does C0292 mean?
Modern brake and stability systems don't work in isolation — the electronic brake control module (EBCM) shares data with the powertrain control module (PCM) and other modules over a serial-data network (typically a CAN bus). The PCM normally sends the EBCM a regular state-of-health message and information such as engine torque and RPM shortly after the modules power up. C0292 sets when the EBCM does not receive those expected messages from the PCM within the allowed time, so it concludes it has lost the data it needs from the powertrain side.
This is a network/communication fault rather than a mechanical brake problem. It can be caused by a genuine problem in the PCM, but just as often it's the wiring or connections between the modules — a damaged data-bus wire, a corroded connector, or a power/ground problem at one of the modules that knocks it off the network. Because the whole network shares the same bus, a single wiring or connector fault can set lost-communication codes in several modules at once, so the presence of matching codes elsewhere is a useful clue.
With C0292 active, the EBCM usually disables traction and stability control (which depend on powertrain data) and turns on the ABS and traction/stability warning lights. Your ordinary brakes still stop the car normally. Start diagnosis by checking for related communication codes across all modules and confirming each module has good power and ground before condemning the PCM or EBCM. Definitions vary by manufacturer — this code is common on GM vehicles — so confirm the specifics in service data for your vehicle.
Common causes
- Damaged, open, or shorted serial-data (CAN bus) wiring between the PCM and EBCM
- Corroded, loose, or backed-out connector at the PCM, EBCM, or an inline junction
- Poor power or ground at the PCM or EBCM knocking it off the bus
- Low system voltage or a weak battery disrupting communication
- Faulty PCM not transmitting the expected data
- Faulty EBCM not receiving/processing bus data (less common)
Symptoms
- ABS warning light on
- Traction control and stability control warning lights on
- Traction and stability features disabled
- Possible additional lost-communication (U-series) codes in other modules
- Normal (base) braking still works
Diagnostic steps
- 1.Scan every module, not just the ABS module, and record C0292 alongside any lost-communication codes elsewhere — a shared bus fault often sets several at once.
- 2.Confirm the PCM and EBCM each have clean, tight power and ground; low voltage or a bad ground can drop a module off the network.
- 3.Inspect the serial-data wiring and connectors between the PCM and EBCM for damage, corrosion, or moisture intrusion.
- 4.Check data-bus integrity per service data (resistance/voltage checks on the CAN circuit) to find opens, shorts, or high resistance.
- 5.Load-test the battery and verify charging-system voltage.
- 6.If the bus, power, and grounds are all good and only the PCM is silent, evaluate the PCM; if only the EBCM can't receive, evaluate the EBCM — but rule out wiring first.
Repair cost
$100 – $1,200
If the cause is wiring, a connector, a ground, or low voltage, the repair is relatively inexpensive — often $100-$400 of diagnostic and repair labor. If a module is genuinely at fault, a PCM or EBCM replacement with programming runs much higher, commonly $500-$1,200+. Because a single bus or ground fault can mimic a dead module, thorough diagnosis before parts replacement saves money here.

DIY vs shop
This is an advanced DIY job. It typically requires specialty tools, scan-tool access, lifting equipment, or careful sequencing to avoid causing new failures. Plan for extended downtime and have a backup vehicle. Most owners are better served by a shop that has done this repair before.
