id0102j5148900

DTC P1200:00

Fuel injection amount learning not completed

DETECTION CONDITION

•  Fuel injection amount learning is not completed normally.

Diagnostic support note

•  This is an intermittent monitor (fuel system).

•  The check engine light does not illuminate.

•  FREEZE FRAME DATA/Snapshot data is available.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

Not applicable

POSSIBLE CAUSE

•  Fuel injection amount learning is not completed because connection between DLC-2 and M-MDS was temporarily loosened during fuel injection amount learning

•  Fuel injector malfunction

•  Engine mechanical system malfunction

―  Poor engine compression

•  PCM malfunction

Diagnostic Procedure

Step

Inspection

Results

Action

1

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

Note

•  Recording can be facilitated using the screen capture function of the PC.

•  Record the freeze frame data/snap shot data.

Go to the next step.

2

VERIFY OTHER RELATED DTCs

•  Switch the ignition OFF, and then switch it ON (engine off).

•  Display the DTCs using the M-MDS.

•  Has any DTC other than P1200:00 been stored?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

Go to the next step.

3

INSPECT DLC-2 CONNECTION CONDITION

•  Switch the ignition OFF.

•  Inspect the engagement/connection condition between DLC-2 and M-MDS, or inspect the terminals for damage, deformation, corrosion, or disconnection.

•  Is the connection condition normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location, then go to Step 7.

4

INSPECT FUEL INJECTOR

•  Inspect the fuel injector.

•  Are the fuel injectors normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location, then go to Step 7.

5

PERFORM FUEL INJECTION LEARNING

•  Perform the fuel injection learning.

•  Start the engine.

•  Verify the warning/indicator light condition.

•  Do the warning/indicator lights turn off?

Yes

Go to the next step.

No

Verify that the implementation conditions for fuel injection amount learning are met, and perform the PCM fuel injection amount learning again.

Go to the next step.

6

VERIFY DTCs

•  Reconnect all disconnected connectors and hoses.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.

•  Display the DTCs using the M-MDS.

•  Is DTC P1200:00 displayed?

Yes

Repeat the inspection from Step 1.

•  If a malfunction occurs, change the learning method (use/do not use M-MDS), and perform the fuel injection amount learning again.

Go to the next step.

No

Go to Step 8.

7

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

•  Reconnect all disconnected connectors and hoses.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.

•  Perform the KOEO or KOER self-test.

•  Has DTC P1200:00 been recorded?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the PCM, then go to the next step.

No

Go to the next step.

8

VERIFY OTHER DTCs

•  Has any other DTC or pending code been stored?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
