Torque Management Request Output Signal
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.
Affected components
- Torque management output
Common causes
- High likelihood: Open or shorted output line
- Medium likelihood: Downstream consumer not loading the line
Diagnostic notes
- The malfunction indicator lamp may illuminate
