Code P0882: Malfunction
of Power Supply System (Low) <Vehicles without AS&G system>
Code P0883:
Malfunction of Power Supply System (high) <Vehicles without AS&G system>
DIAGNOSTIC FUNCTION
JUDGEMENT CRITERIA
- <P0882>: When the engine speed is 450 r/min or more
and secondary pressure is above 0.3 MPa, the power supply voltage is 9.0 V or less (for 5 seconds)
- <P0883>: When the engine speed is 450 r/min or more,
the secondary pressure is above 0.3 MPa and the vehicle speed is 1 km/h or more, the power
supply voltage is 16.0 V or more (for 5 seconds)
PROBABLE CAUSES
- Damaged wiring harness and connectors
- Malfunction of CVT-ECU
