Diagnostic Procedure

DIAGNOSTIC PROCEDURE DESCRIPTION

STEP	INSPECTION	RESULTS	ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION NOTE: Recording can be facilitated using the screen capture function of the PC. Record the snapshot data on the repair order.	-	Go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY 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.
2		No	Go to the next step.
3	VERIFY DTC REPEATABILITY Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Perform the KOER self test. (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Is the same 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, 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.
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, then go to Step 12. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
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 ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) 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.
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 part according to the inspection results, then go to Step 12.
7		No	APP sensor malfunction. Replace the accelerator pedal, then go to Step 12. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
8	VERIFY CURRENT INPUT SIGNAL STATUS OF BRAKE SWITCH Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) BOO BPA Are all PIDs normal? (See PCM INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)	Yes	Go to Step 11.
8		No	Go to the next step.
9	INSPECT BRAKE SWITCH Inspect the brake switch. (See BRAKE SWITCH INSPECTION .) Is there any malfunction?	Yes	Replace the brake switch, then go to Step 12. (See BRAKE PEDAL REMOVAL/INSTALLATION .)
9		No	Go to the next step.
10	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 Step 12.
10		No	Repair or replace the malfunctioning part according to the inspection results, then go to Step 12.
11	VERIFY IF A DTC RELATED TO DRIVE-BY-WIRE CONTROL IS DETECTED Perform the KOER self test. (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Is a DTC related to the drive-by-wire control present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .)
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.
12	VERIFY DTC TROUBLESHOOTING COMPLETED Always reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Perform the KOER self test. (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Go to the next step.
12		No	Go to the next step.
13	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .)
13		No	DTC troubleshooting completed.
