DTC P062D Fuel Injector Driver Circuit Performance Bank 1: Notes

DTC DETECTING CONDITION: 

Immediately at fault recognition

TROUBLE SYMPTOM: 

• Engine does not start.
• Engine stalls.
  CAUTION:

  • After servicing or replacing faulty parts, perform Clear Memory Mode <Ref. to OPERATION , Clear Memory Mode.>, and Inspection Mode <Ref. to PROCEDURE , Inspection Mode.>.
  • Use the check board when measuring the ECM terminal voltage and resistance.

Step	Check	Yes	No
1 CHECK FOR ANY OTHER DTC ON DISPLAY.	Is any other DTC displayed?	Check the appropriate DTC using the "List of Diagnostic Trouble Code (DTC)". <Ref. to List of Diagnostic Trouble Code (DTC) .>	Go to step 2  .
2 CHECK HARNESS BETWEEN ECM AND FUEL INJECTOR CONNECTOR.  Turn the ignition switch to OFF. Disconnect the connector from ECM. Measure the resistance between ECM connectors. Connector & terminal  #1 (E158) No. 11 - (E158) No. 12:  #2 (E158) No. 23 - (E158) No. 24:  #3 (E158) No. 35 - (E158) No. 36:  #4 (E158) No. 47 - (E158) No. 48:	Is resistance 1.89 - 2.31 Ω at 20°C (68°F)?	Go to step 4  .	Go to step 3  .
3 CHECK HARNESS BETWEEN ECM AND FUEL INJECTOR CONNECTOR.  Disconnect the connector from fuel injector. Measure the resistance of harness between ECM connector and defective fuel injector connector. Connector & terminal  #1 (E158) No. 12 - (E5) No. 1:  #1 (E158) No. 11 - (E5) No. 2:  #2 (E158) No. 24 - (E16) No. 1:  #2 (E158) No. 23 - (E16) No. 2:  #3 (E158) No. 36 - (E6) No. 1:  #3 (E158) No. 35 - (E6) No. 2:  #4 (E158) No. 48 - (E17) No. 1:  #4 (E158) No. 47 - (E17) No. 2:	Is the resistance less than 1 Ω?	Repair or replace the following items. Poor contact of fuel injector connector Defective fuel injector <Ref. to FUEL INJECTOR .>	Repair the open circuit of the harness between the ECM connector and fuel injector connector.
4 CHECK HARNESS BETWEEN ECM AND FUEL INJECTOR CONNECTOR.  Measure the resistance between the ECM connector and engine ground. Connector & terminal  #1 (E158) No. 12 - Engine ground:  #1 (E158) No. 11 - Engine ground:  #2 (E158) No. 24 - Engine ground:  #2 (E158) No. 23 - Engine ground:  #3 (E158) No. 36 - Engine ground:  #3 (E158) No. 35 - Engine ground:  #4 (E158) No. 48 - Engine ground:  #4 (E158) No. 47 - Engine ground:	Is the resistance 1 MΩ or more?	Repair the poor contact of ECM connector.	Go to step 5  .
5 CHECK HARNESS BETWEEN ECM AND FUEL INJECTOR CONNECTOR.  Disconnect the connector from fuel injector. Measure the resistance between ECM connector and engine ground on defective fuel injectors. Connector & terminal  #1 (E158) No. 12 - Engine ground:  #1 (E158) No. 11 - Engine ground:  #2 (E158) No. 24 - Engine ground:  #2 (E158) No. 23 - Engine ground:  #3 (E158) No. 36 - Engine ground:  #3 (E158) No. 35 - Engine ground:  #4 (E158) No. 48 - Engine ground:  #4 (E158) No. 47 - Engine ground:	Is the resistance 1 MΩ or more?	Replace the faulty fuel injector. <Ref. to FUEL INJECTOR .>	Repair the short circuit to ground in harness between ECM connector and fuel injector connector.
