Prius Nightshade FWD: OEM-published Engine displacement reference is 2.0 L. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.

Prius Nightshade FWD: OEM-published Cylinders reference is 4. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.

Prius Nightshade FWD: OEM-published THS generation reference is 5. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.

Prius Nightshade FWD: OEM-published Net system power reference is 194 hp. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.

Higher fuel consumption or lower-than-expected electric assist

Change in regenerative-brake feel / warning lamp

Harsh engine engagement, reduced power or thermal warning

Log HV battery SOC, block/cell voltage deviation, inverter temperatures and motor-generator torque command during the same drive event with an OEM-compatible scan tool.

Measure 12 V supply and ground voltage drop under load; weak auxiliary power can disturb hybrid ECU communication and contactor operation.

Separate ICE fuel/ignition power loss from HV battery/inverter limitation by comparing engine load, fuel trims and HV power-limit data together.

Differentiate brake drag from hybrid energy-recovery faults by comparing wheel temperature/physical drag findings with regenerative torque command.

Preserve DTC freeze-frame, INF/sub-code and fail-safe conditions where available; do not condemn a component from the headline DTC alone.

No warning should return through cold start, full warm-up and city/highway load cycles; fuel/energy and thermal live data should return to normal operating patterns.

Prius: Evaluate hybrid control, engine ECU, battery ECU, brake/ABS and body network together.

Prius: HV battery SOC and block/cell voltages.

Prius: HV battery temperature sensors.

Prius: Inverter / motor-generator temperature and torque data.

Prius: Regenerative-brake torque request and brake ECU data.

Prius: 12 V DC/DC and auxiliary supply.

Prius: Engine load and lambda/fuel trims.
