If simulation function of M-MDS is used:
OPERATION OF FUEL INJECTOR INSPECTION
| STEP | INSPECTION | ACTION | |
|---|---|---|---|
| 1 | Start the engine and warm it up until normal operating temperature. Connect the M-MDS to DLC-2. Select the INJ#1, INJ#2, INJ#3, and INJ#4 PIDs. Turn the fuel injector from on to off using the PIDs for each cylinder. Does the engine speed drop? |
Yes | Fuel injector work properly |
| No | Engine speed does not drop an any cylinder: Go to the next steps. Engine speed drops on some cylinders: Go to step 3. |
||
| 2 | Perform the Main Relay Operation Inspection. (See MAIN RELAY OPERATION INSPECTION ). Does the main relay work properly? |
Yes | Go to the next step. |
| No | Repair or replace the malfunctioning parts. | ||
| 3 | Inspect the fuel injector of the suspected cylinder. Is the fuel injector normal? |
Yes | Inspect the following for the suspected cylinder.
If all items normal replace the PCM. (See PCM REMOVAL/INSTALLATION .) |
| No | Replace the fuel injector. | ||
| 4 | Perform KOER self-test function using the M-MDS. (See KOEO/KOER SELF TEST .) Are DTCs P0201, P0202, P0203 and/or P0204 present? |
Yes | Go to the appropriate DTC test. (See DTC TABLE .) |
| No | Go to the next step. | ||
| 5 | Inspect the fuel injector of the suspected cylinder. Is the fuel injector normal? |
Yes | Inspect the following for the suspected cylinder:
If all items are normal replace the PCM. (See PCM REMOVAL/INSTALLATION .) |
| No | Replace the fuel injector. | ||
