Diagnose soon
Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
Torque Management Request Output Signal
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The ECM/PCM produces a torque-management output signal for downstream consumers (TCM during shifts, hybrid module, transfer case) and detects a fault on this output — open, short, or feedback voltage outside expected range. Without it, downstream modules cannot synchronise their behaviour with the engine.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.

| 1 | Open or shorted output line | Very common | — |
| 2 | Downstream consumer not loading the line | Common | — |
Ordering reflects how often each cause is responsible in general, not a probability for your vehicle. Confirm by testing.
