id0102s4327200

DTC P2299:00

Accelerator pedal: spring back malfunction

DETECTION CONDITION

•  The brake pedal is depressed for the specified time^* or more when any of the following conditions is met with the accelerator pedal depressed.

While driving vehicle:

―  Accelerator pedal opening angle: 5% or more from fully closed

―  Vehicle speed: 10 km/h {6.2 mph} or more

―  Engine speed: 1,150 rpm or more

While vehicle is stopped:

―  Accelerator pedal opening angle: 5% or more from fully closed

―  Shift lever position: neutral (MTX)

―  Selector lever position: N position (ATX)

―  Engine speed: 1,150 rpm or more

Diagnostic support note

•  This is a continuous monitor (other).

•  The check engine light does not illuminate.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.

•  DTC is not stored in the PCM memory.

FAIL-SAFE FUNCTION

Not applicable

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

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	VERIFY DTC REPEATABILITY • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Start the engine and warm it up completely. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) • Is the same DTC present?	Yes	Go to the next step.
2		No	DTC troubleshooting completed. • Explain to the customer that P2299:00 is stored by the brake override system operation.
3	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 Step 10. 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 10.
3		No	Go to the next step.
4	INSPECT APP SENSOR • 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 10. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
4		No	Go to the next step.
5	VERIFY CURRENT INPUT SIGNAL STATUS OF APP SENSOR • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) ― APP1 ― APP2 • Does the value for PID APP1, APP2 change when the accelerator pedal is continually depressed?	Yes	Go to Step 7.
5		No	Go to the next step.
6	INSPECT APP SENSOR RELATED WIRING HARNESS AND CONNECTOR • 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 10.
6		No	APP sensor malfunction. • Replace the accelerator pedal, then go to Step 10. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
7	VERIFY CURRENT INPUT SIGNAL STATUS OF BRAKE SWITCH • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) ― BOO ― BPA • Are all PIDs normal? (See PCM INSPECTION [SKYACTIV-D 2.2].)	Yes	It is possible that the accelerator and brake pedals have been depressed simultaneously. (during braking operation using left foot) • Go to Step 10.
7		No	Go to the next step.
8	INSPECT BRAKE SWITCH • Inspect the brake switch. (See BRAKE SWITCH INSPECTION.) • Is there any malfunction?	Yes	Replace the brake switch, then go to Step 10. (See BRAKE PEDAL REMOVAL/INSTALLATION [R.H.D.].) (See BRAKE PEDAL REMOVAL/INSTALLATION [L.H.D.].)
8		No	Go to the next step.
9	INSPECT BRAKE PEDAL PLAY AMOUNT • Inspect the brake pedal play amount. (See BRAKE PEDAL INSPECTION.) • Is the amount of brake pedal play normal?	Yes	Inspect the wiring harness related to the brake switch for connector disconnection, short circuit, and poor contact. • If there is any malfunction: ― Repair or replace the malfunctioning part according to the inspection results, then go to the next step.
9		No	Repair or replace the malfunctioning part according to the inspection results, then go to the next step.
10	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Start the engine and warm it up completely. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].) Go to the next step.
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 2.2].)
11		No	DTC troubleshooting completed.
