Code No. C2007: Power supply high voltage (VP)
OPERATION
The EV-ECU control power supply is applied to the EV-ECU via a fuse with the power switch set to the ON position.
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
|
|
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.
