DTC P2299:00 | Brake pedal position/Accelerator pedal position incompatible
--- | ---
DETECTION CONDITION | • Brake override system operates.
POSSIBLE CAUSE | • 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) • 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 • 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.
No | Go to the next step.
2 | 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 [MZI-3.7].)
No | Go to the next step.
3 | VERIFY CURRENT INPUT SIGNAL STATUS OF APP SENSOR • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7].) ― 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 5.
4 | 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.
No | APP sensor malfunction. • Replace the accelerator pedal, then go to Step 10. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [MZI-3.7].)
5 | VERIFY CURRENT INPUT SIGNAL STATUS OF BRAKE SWITCH • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7].) ― BOO ― BPA • Are all PIDs normal? | Yes | Go to Step 8.
No | Go to the next step.
6 | 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 [L.H.D.].) (See BRAKE PEDAL REMOVAL/INSTALLATION [R.H.D.].)
No | Go to the next step.
7 | INSPECT BRAKE PEDAL PLAY AMOUNT • Inspect the brake pedal play amount. (See BRAKE PEDAL INSPECTION [L.H.D.].) (See BRAKE PEDAL INSPECTION [R.H.D.].) • 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 10.
No | Repair or replace the malfunctioning part according to the inspection results, then go to Step 10.
8 | VERIFY IF A DTC RELATED TO DRIVE-BY-WIRE CONTROL IS DETECTED • Perform the KOER self test. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is a DTC related to the drive-by-wire control present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Go to the next step.
9 | VERIFY CONDITION OF FLOOR MAT • Is the condition of the driver side floor mat one of the following? ― Floor mat is doubled over ― Floor mat is spread against the accelerator pedal | Yes | Explain to the customer that the floor mat is preventing the accelerator pedal from springing back after release. • Go to the next step.
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.
10 | 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 [MZI-3.7].) • Perform the KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is the same DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
