DTC P2299 | Accelerator pedal: spring back malfunction
--- | ---
DETECTION CONDITION | • Brake override system operates. Diagnostic support note • This is a continuous monitor (other). • The MIL does not illuminate. • FREEZE FRAME DATA is not available. • Snapshot data is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE | Note • If the brake override system operates, the PCM detects DTC P2299. • Driver depresses accelerator and brake pedals simultaneously (during braking operation using left foot) • Accelerator pedal is pressed in due to 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 SNAPSHOT DATA HAS BEEN RECORDED • Has the snapshot data been recorded? | Yes | Go to the next step.
No | Record the snapshot data on the repair order, then go to the next step.
3 | 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.
No | Go to the next step.
2 | 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 11. 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 11.
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 11. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [L8, LF].)
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 [L8, LF].) ― IVS ― APP1 ― APP2 • Is the value for PID IVS Idle when the accelerator pedal is not depressed? • Do the values for PIDs APP1 and APP2 change when the accelerator pedal is continually depressed? | Yes | Go to the next step.
No | Go to Step 7.
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 11.
No | APP sensor malfunction. • Replace the accelerator pedal, then go to Step 11. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [L8, LF].)
7 | VERIFY CURRENT INPUT SIGNAL STATUS OF BRAKE SWITCH • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [L8, LF].) ― BOO ― BPA • Are all PIDs normal? | Yes | Go to Step 10.
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 11. (See BRAKE PEDAL REMOVAL/INSTALLATION.)
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 Step 11.
No | Repair or replace the malfunctioning part according to the inspection results, then go to Step 11.
10 | VERIFY IF A DTC RELATED TO DRIVE-BY-WIRE CONTROL IS DETECTED • Perform the KOER self test. (See KOEO/KOER SELF TEST [L8, LF].) • Is a DTC related to the drive-by-wire control present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L8, LF].)
No | Go to the next step.
11 | VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L8, LF].) Caution • While performing this step, always operate the vehicle in a safe and lawful manner. • When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. • Drive the vehicle under the snapshot data condition. • Perform the KOER self test. (See KOEO/KOER SELF TEST [L8, LF].) • Is the same DTC present? | Yes | Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [L8, LF].) Go to the next step.
No | Go to the next step.
12 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L8, LF].)
No | DTC troubleshooting completed.
