DTC P2299:00 [PCM (SKYACTIV-G)]

SM2334462


id0102t4327200



Outline

System malfunction location

Accelerator pedal: spring back malfunction

Detection condition
• When under the following conditions it is detected that the brake pedal is depressed during driving. *
― Racing
― Engine speed: 875 rpm or more
*: The brake override system may not operate depending on the brake pedal depression amount.
Fail-safe
• Controls the throttle valve so that the engine speed is at specification *. (Brake override system) * : For MTX vehicles, engine speed is 1,200 rpm when in neutral, and 1,100 rpm when not in neutral. For ATX vehicles, engine speed is 1,200 rpm when in N position, and 1,100 rpm when in D position.
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

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.
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.
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.
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.
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.
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.
No
APP sensor malfunction.
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
Yes
Go to Step 11.
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.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
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.
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.
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.
If the CAN communication is normal, perform the diagnosis from Step 1.
No
Go to the next step.
Repair completion verification 2
