PEC diagnosis operational check using actual values, chassis dynamometer

The test values are minimum outputs. Vehicle speed not above 130 km/h; use workshop test tires.

The engine coolant and intake air temperature cannot be simulated due to the PEC system. Provide sufficient cooling with a blower during wide open throttle output measurement.
