Diagnostic Procedure

Step

Inspection

Results

Action

1

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

•  Record the freeze frame data/snapshot data.

Note

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

—

Go to the next step.

2

VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY

•  Verify related Service Bulletins, on-line repair information, or Service Information availability.

•  Is any related Information available?

Yes

Perform repair or diagnosis according to the available information.

•  If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

VERIFY DTC REPEATABILITY

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Start the engine and warm it up completely.

•  Perform the DTC inspection for the PCM.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Go to the next step.

No

DTC troubleshooting completed.

•  Explain to the customer that P2299:00 is stored by the brake override system operation.

4

VERIFY VEHICLE USE CONDITION

•  Verify the vehicle use condition.

―  The floor mat is doubled over

―  The floor mat is spread against the accelerator pedal

―  The accelerator and brake pedals are being depressed simultaneously

•  Are any of the conditions above applicable to vehicle use condition?

Yes

There is a malfunction in a related floor mat

•  Explain to the customer that the floor mat may prevent the accelerator pedal from springing back after release, then go to repair completion verification.

There is a malfunction in the pedal operation

•  Give the customer advice on how to depress the accelerator and brake pedals while driving the vehicle, then go to repair completion verification.

No

Go to the next step.

5

INSPECT ACCELERATOR PEDAL

•  Is the condition of the accelerator pedal one of the following?

―  There is evidence of accelerator pedal disassembly

Yes

Repair or replace the malfunctioning location and perform the repair completion verification.

(See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

No

Go to the next step.

6

VERIFY CURRENT INPUT SIGNAL STATUS OF APP SENSOR

•  Access the following PIDs using the M-MDS:
(See PID/DATA MONITOR INSPECTION.)

PCM

―  APP1

―  APP2

•  Does the value for PID APP1, APP2 change when the accelerator pedal is continually depressed?

Yes

Go to Step 8.

No

Go to the next step.

7

INSPECT APP SENSOR RELATED WIRING HARNESS AND CONNECTOR

•  Is there any malfunction?

Yes

Repair or replace the malfunctioning location and perform the repair completion verification.

No

APP sensor malfunction.

•  Replace the accelerator pedal, then go to repair completion verification.
(See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

8

―  BRK_SW1

―  BRK_SW2

•  Are all PIDs normal?
(See PCM INSPECTION [SKYACTIV-D 1.8].)

Yes

It is possible that the accelerator and brake pedals have been depressed simultaneously. (during braking operation using left foot)

•  Go to repair completion verification.

No

Go to the next step.

9

INSPECT BRAKE SWITCH FOR MALFUNCTION

•  Inspect the applicable part.
(See BRAKE SWITCH INSPECTION.)

•  Is the part normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification.

(See BRAKE PEDAL REMOVAL/INSTALLATION [L.H.D. (E)].)

10

INSPECT BRAKE PEDAL PLAY AMOUNT

•  Inspect the brake pedal play amount.
(See BRAKE PEDAL INSPECTION [(E)].)

•  Is the amount of brake pedal play normal?

Yes
