DTC P2299:00 (PCM, SKYACTIV-G) 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.
2		No	Go to the next step.
3	VERIFY DTC REPEATABILITY Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform the KOER self test. (See DTC INSPECTION .) Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Go to the next step.
3		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 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 and perform the 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 and perform the repair completion verification.
4		No	Go to the next step.
5	INSPECT ACCELERATOR PEDAL 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 and perform the repair completion verification. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION (VIN M) .) (See ACCELERATOR PEDAL REMOVAL/INSTALLATION (VIN 7, L) .)
5		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: APP_MODE APP1 APP2 Inspect the following: Is the value for PID APP_MODE 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.
6		No	Go to the next step.
7	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 location and perform the repair completion verification.
7		No	APP sensor malfunction. Replace the accelerator pedal and perform the repair completion verification. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION (VIN M) .) (See ACCELERATOR PEDAL REMOVAL/INSTALLATION (VIN 7, L) .)
8	VERIFY CURRENT INPUT SIGNAL STATUS OF BRAKE SWITCH Access the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION .) Electrical supply unit (ESU): BRK_SW Are all PIDs normal? (See PID/DATA MONITOR TABLE [ELECTRICAL SUPPLY UNIT (ESU) (US)] .)	Yes	Go to Step 11.
8		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.
9		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See BRAKE PEDAL REMOVAL/INSTALLATION [L.H.D. (US)] .)
10	INSPECT BRAKE PEDAL PLAY AMOUNT Inspect the brake pedal play amount. (See BRAKE PEDAL INSPECTION [(US)] .) 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 location and perform the repair completion verification.
10		No	Repair or replace the malfunctioning location and perform the repair completion verification.
11	VERIFY IF A DTC RELATED TO DRIVE-BY-WIRE CONTROL IS DETECTED Perform the KOER self test. (See DTC INSPECTION .) Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Is a DTC related to the drive-by-wire control present?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-G (US))] .)
11		No	It is possible that the accelerator and brake pedals have been depressed simultaneously. (during braking operation using left foot) Go to the next step.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Replicate the vehicle conditions at the time the DTC was detected using the following procedure. Perform the KOER self test. (See DTC INSPECTION .) Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)] .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION (VIN M) .) (See PCM REMOVAL/INSTALLATION (VIN 7, L) .)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
