Code No. C2007: Power supply high voltage (VP)


OPERATION



DIAGNOSIS CODE SET CONDITIONS



  • When the control power supply voltage of 16 V or more continues, the diagnosis code No. C2007 will be set.

PROBABLE CAUSES



  • 24-V battery incorrect connection by user
  • Malfunction of the auxiliary battery
  • Malfunction of the DC-DC converter
  • Malfunction of the EV-ECU

DIAGNOSIS PROCEDURE

STEP 1. ?Check whether the diagnosis code is set.
Check if the diagnosis code No. P0A09 for other systems is set to the EV-ECU.

Q. Is the diagnosis code set?
Carry out troubleshooting for the diagnosis code P0A09. (Refer to .)
Go to Step 2.

STEP 2. M.U.T.-III actuator test and service data
Perform the actuator test (refer to ), and check the service data of the EV control relay (refer to ).
Actuator test
  • Item No. 2 : 12 V DC DC shutdown
Data list
  • Item No. 83 : Control power supply voltage
OK: The voltage value varies between 3.7 V and 3.9 V / 3.3 V and 3.5 V depending on activation / deactivation of the DC-DC converter.

Q. Is the check result normal?
Go to Step 3.
Carry out the troubleshooting for the EV-ECU diagnosis code P0A09. (Refer to .)

STEP 3. Diagnosis code recheck
Check again if the diagnosis code is set to the EV-ECU.
(1)Erase the stored diagnosis code.
(2)Set the electric motor switch from the LOCK (OFF) position to the ON position.
(3)Check if the diagnosis code is set.

Q. Is the diagnosis code set?
Replace the EV-ECU. (Refer to .) Then go to Step 4.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction .)

STEP 4. Diagnosis code recheck
Check again if the diagnosis code is set to the EV-ECU.
(1)Erase the stored diagnosis code.
(2)Set the electric motor switch from the LOCK (OFF) position to the ON position.
(3)Check if the diagnosis code is set.

Q. Is the diagnosis code set?
Return to Step 1.
The diagnosis is complete.
