DTC P2299:00

Accelerator pedal: spring back malfunction

DETECTION CONDITION

• When under the following conditions it is detected that the brake pedal is depressed during driving for the specified time^*.

• Racing

• Engine speed: 875 rpm or more

• ^*: Specified time is 0.6—10 s according to braking force calculated in PCM.

Diagnostic support note

• This is a continuous monitor (other).

• The check engine light does not illuminate.

• FREEZE FRAME DATA is not available.

• Snapshot data is available.

• DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

• Controls the throttle valve so that the engine speed is at specification^*. (Brake override system)

  *: For MT vehicles, engine speed is 1,200 rpm when in neutral, and 1,100 rpm when not in neutral. For AT vehicles, engine speed is 1,200 rpm when in N position, and 1,100 rpm when in D position.

POSSIBLE CAUSE

NOTE:

• If the brake override system operates, the PCM detects DTC P2299:00.

• Driver depresses accelerator and brake pedals simultaneously (during braking operation using left foot)

• Accelerator pedal is pressed in by object such as floor mat

• Accelerator pedal sticking

• APP sensor signal malfunction

• APP sensor malfunction

• Related connector or terminals malfunction

• Related wiring harness malfunction

• Brake switch signal malfunction

• Brake switch malfunction

• Related connector or terminals malfunction

• Related wiring harness malfunction

• Brake pedal malfunction (increase in play due to joint pin wear)

• PCM malfunction

Go to the next step.

2

• Verify related Service Bulletins and/or on-line repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

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

No

Go to the next step.

3

• Clear the DTC from the PCM memory using the M-MDS.

  (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.0)].)

• Perform the KOER self test.

  (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.0)].)

• Is the same 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 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 the 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 Step 12.

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 Step 12.

No

Go to the next step.

5

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

• Accelerator pedal sticking has occurred when operated

• There is evidence of accelerator pedal disassembly

Yes

Replace the accelerator pedal, then go to Step 12.

(See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

No

Go to the next step.

6

• Access the following PIDs using the M-MDS:

  (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0)].)

• IVS

• APP1

• APP2

• Inspect the following:

• Is the value for PID IVS Idle when the accelerator pedal is not depressed?

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

• Are all items normal?

Yes

Go to Step 8.

No

Go to the next step.

7

• Inspect the wiring harness related to the APP sensor for connector disconnection, short circuit, and poor contact.

• Is there any malfunction?

Yes

Repair or replace the malfunctioning part according to the inspection results, then go to Step 12.

No

APP sensor malfunction.

• Replace the accelerator pedal, then go to Step 12.

  (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

8

• Access the following PIDs using the M-MDS:

  (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0)].)

• BPA

• Are all PIDs normal?

  (See PCM INSPECTION [SKYACTIV-G 2.0].)

Yes

Go to Step 11.

No

Go to the next step.

9

• Inspect the brake switch.

  (See BRAKE SWITCH INSPECTION.)
