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.
(See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].)
(See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
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.
• Replace the accelerator pedal and perform the repair completion verification. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
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.
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.
(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.
