DOCUMENTED DIAGNOSTIC CONTEXT

Diagnostic code articles — Page 19.

Understand what the recorded fault means, which findings change the diagnosis, and what the cited documentation can confirm. Each article states the system or vehicle scope it covers.

Some sources leave details unresolved. Those articles include a visible source note; a code match alone does not establish applicability to your vehicle.

motor B phase U performance checks the offset with power stage open

motor B phase U low is an electrical-range check

motor B phase U high must be interpreted in the disabled-output state

motor B phase V offset has a source phase-name discrepancy

motor B phase V low is evaluated with PWM output disabled

motor B phase V high is tested with PWM disabled

motor B phase W offset must be read despite a copied phase label

motor B phase W low is a disabled-output sensing check

motor B phase W high is a sensor-range finding

motor A phase-current correlation is different from one high sensor

motor B correlation uses the three phase-current reports together

motor A overcurrent has fast and intermittent detection branches

motor B overcurrent is filtered through two protective paths

motor A missing-current detection depends on rotor position

motor B circuit-open detection uses a position-dependent current test

motor A inverter supply failure is reported through a bias-status flag

motor B inverter power-supply faults use an internal status indication

motor A phase U overheating requires a credible temperature signal

motor A phase V thermal monitoring uses PIM Temp 2

motor A phase W overheating is judged from a validated sensor channel

motor B phase U overheating depends on PIM Temp 2 validity

motor B phase V thermal diagnosis uses PIM Temp 0

motor B phase W overheating is separate from sensor circuit failure

motor A resolver learning can fail without proving a bad position sensor

motor B not-learned status needs the reason for learning failure

motor A torque performance combines several security checks

motor B torque performance needs the failed branch identified

Pump phase-current absence depends on command and rotor angle

Auxiliary-pump undercurrent is a decoded operating report, not feedback duty low

Auxiliary-pump overcurrent must not be confused with feedback duty high

The pump performance category combines current and speed evidence

A reported pump stall does not prove the motor is permanently seized

auxiliary transmission-pump feedback is a communication check here

Auxiliary-pump feedback frequency is separate from encoded pump performance

Low feedback duty cycle is not the same as low pump current

High feedback duty cycle must be separated from pump overcurrent
