Status displayed on SUZUKI scan tool | Detecting condition | Indicator / Warning light operation |
---|---|---|
*CO | Open circuit | MIL and injection warning light (gravity 1 fault) light up |
*CC | Short circuit | |
D1 | Parameter at limit minimum | Injection warning light (gravity 1 fault) light up |
D2 | Parameter at limit maximum |
Switch off the ignition and wait 15 seconds.
Check the connection and condition of the injector connector. Repair if necessary. |
|
Check the connection and condition of the ECM “C47” connector.
Repair if necessary. |
|
Using SUZUKI scan tool, carry out the “Cylinder 2 Injector” (in output test on scan tool).
If injector 2 cannot be heard operating five times in a cycle, connect the wire of the injector of cylinder 3 to the injector of cylinder 2 and carry out the “Cylinder 3 Injector” (in output test on scan tool). Does this injector actuation cycle work? |
|
Yes | Injector 2 is not defective; the fault is in the injector 1 control circuit. |
Check for continuity and absence of interference resistance of the connections:
•
Between “C47-42” terminal of ECM connector and “C37-1” terminal of injector No.2 connector
Repair if necessary.
• Between “C47-41” terminal of ECM connector and “C37-2” terminal of injector No.2 connector |
|
If DTC P0202 is still detected, replace the ECM. | |
No | Injector 2 is faulty, replace the cylinder 2 injector. |
Check that the injector calibration codes are registered correctly in the ECM. |
Check the connection and condition of the “C47-9” terminal of ECM connector.
Repair if necessary. |
Check that the knock sensor is secured on the engine.
Repair if necessary. |
After retightening the knock sensor, initialize the fuel pressure value by using “Initialize High Pressure Pump” under “Miscellaneous test” (“MISC TEST”) of SUZUKI scan tool. |
If DTC P0202 is still detected, replace the cylinder 2 injector. |
