OBD-II Code
C0062
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$25–$1,400
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$25 (external relay) to $1,400 (full OEM module + programming).
C0062 is a short-to-battery fault in the ABS solenoid valve relay circuit — the EBCM is detecting that the relay coil control circuit is being held at battery voltage when the module commands it open, which means either the relay coil is internally shorted, the relay drive transistor inside the EBCM has failed, or the wiring between EBCM and relay has chafed against a +12V source.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

C0062 is a short-to-battery fault in the ABS solenoid valve relay circuit — the EBCM is detecting that the relay coil control circuit is being held at battery voltage when the module commands it open, which means either the relay coil is internally shorted, the relay drive transistor inside the EBCM has failed, or the wiring between EBCM and relay has chafed against a +12V source. The ABS valve relay is the master power-feed relay that energizes all the ABS solenoid valves during a braking event, so when this circuit faults the entire ABS function is disabled and the warning light stays on.
Cheapest-first ladder
- Pull the ABS relay from its socket (usually in the underhood fuse box or the EBCM itself on integrated units) and ohm-check the coil terminals — expect 60-120 ohms across the coil; a reading near zero is a shorted coil, near infinite is an open coil, and either condition can set C0062.
- Inspect the underhood fuse-box terminals for corrosion and the relay socket pins for spread or burnt contacts — a relay socket with a heat-damaged pin throws C0062 and gets misdiagnosed as a bad EBCM.
- Continuity-check the relay control wire from the EBCM to the relay socket with the EBCM unplugged — any continuity to chassis ground or to a +12V source is a wiring fault, not a module fault.
- Swap a known-good relay of the same part number from another circuit (horn, fuel pump, headlamp) to rule out the relay before condemning the EBCM. Expensive-misdiagnosis caveat: GM trucks 1999-2007 with the Kelsey-Hayes 325 EBCM — C0062 on these is most often an internal EBCM failure rather than an external short, and the module is integrated with the hydraulic control unit (HCU) making OEM replacement a $700-$1,400 affair; however, bench-rebuild services (Module Master, MyAirbags, and similar) can rebuild a failed K-H 325 EBCM for $150-$250 with a lifetime warranty, which is the realistic shop-floor option on a 15-year-old truck.

- 1999-2007GM trucks (Silverado/Sierra/Tahoe/Yukon/Suburban/Avalanche) with the Kelsey-Hayes 325 EBCM are the classic C0062 platform — solder joints inside the module crack from underhood thermal cycling and the relay-driver circuit goes open or shorted; bench rebuild is the going repair, full module replacement is the dealer route.
- 2003-2008Dodge Ram 1500/2500/3500 with the Bosch 5.7 ABS module throws C0062 from corroded EBCM connector pins where the connector seal degrades and lets road salt in.
- 2005-2011Ford Mustang/Crown Victoria with Teves Mark 20 systems throw C0062 from a failed underhood ABS relay that's external to the module — a $25 fix once the relay is identified, but commonly misdiagnosed as a module failure.
- 2004-2009Toyota Tacoma/4Runner with the Bosch 8.0 system throws C0062 from a wiring chafe at the EBCM harness clip on the inner fender.
