   HINT: 

   P0D5C-848 may be output due to a malfunction which causes the DTCs in the table above to be output. In this case, first troubleshoot the output DTCs in the table above. Then, perform a reproduction test to check that no DTCs are output.

5. Turn the power switch off.

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Connect an oscilloscope between the plugin charge control ECU assembly terminals specified in the table below.
3. Turn the power switch on (IG).
4. Enter the following menus: Powertrain / Plug-in Control / Data List
5. Select "Request Charge Power Duty Ratio" in the Data List.

   Tester Display	Measurement Item/Range
   Request Charge Power Duty Ratio	Charging power duty value/ Min.: 0.0 %, Max.: 127.5 %

6. Measure the waveform.

   HINT: 

   Calculate duty (%) using the following formula: Duty (%) = T1 / T2 x 100 (%)

8. Compare the Data List item "Request Charge Power Duty Ratio" with the duty (%) calculated based on CHPW waveform.

   Result

   Result	Proceed to
   The difference between "Request Charge Power Duty Ratio" and the duty (%) calculated based on CHPW waveform is less than 25 %.	A
   The difference between "Request Charge Power Duty Ratio" and the duty (%) calculated based on CHPW waveform is 25 % or more.	B

9. Turn the power switch off.
