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

DIAGNOSTIC PROCEDURE


STEP 1. Check for short circuit in power supply line between the fusible link and the CVT control relay connector


Q. Is the check result normal?

Go to Step 2.
Repair the connector(s) or wiring harness.

STEP 2. Check for short circuit in VIG1, VIG2 line between the CVT control relay connector and the CVT-ECU connector.


Q. Is the check result normal?

Go to Step 3.
Repair the connector(s) or wiring harness.

STEP 3. Check for open circuit in GND1, GND2 line between the CVT-ECU connector and earth.


Q. Is the check result normal?

Go to Step 4.
Repair the wiring harness.

STEP 4. Symptom recheck after erasing diagnosis code


Q. Is the check result normal?

Intermittent malfunction
Replace CVT-ECU.
