Diagnostic Test
- CHECK FOR AN ACTIVE DTC NOTE:
If a pedal assembly becomes mechanically stuck the voltage output will stay fixed, if this is also followed by a long application of the brakes this code will set.
NOTE:When this code sets the pedal position in the PCM software will ramp to idle. If the Pedal voltage changes OR the brake pedal is released, the pedal position in the PCM software will ramp up to the pedal position and the ETC light will go out.
- With the scan tool, read DTCs and record the related Freeze Frame data.
- This code can be set by a driver who uses both feet while driving, one for the Accelerator Pedal and the other for the Brake Pedal.NOTE:
The most likely cause of this DTC is caused by the customer driving with one foot on the Accelerator pedal and the other resting on the Brake Pedal.
- Ask the driver of the vehicle if these conditions apply to their driving habits.
Are the listed conditions part of the customers driving habits?
Yes
- Advise the customer of what caused the DTC. This is normal operation of a ETC equipped vehicle because of safety issues.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST, 3.2L . .
No
- Go To 2
- CHECK FOR OTHER DTCS
- Refer to the recorded DTCs.
Are there any other Stop Lamp Switch and APP Sensor DTCs active or pending?
Yes
- Perform the applicable diagnostic procedure(s). Refer to 3.2L - DIAGNOSTIC CODE INDEX .
No
- Go To 3
- Refer to the recorded DTCs.
- CHECK THE STOP LAMP SWITCH FOR PROPER OPERATION
- With the scan tool, read both Stop Lamp Switch statuses while pressing and releasing the Brake Pedal.
Does the scan tool display the Pressed and Released while pressing and releasing the Pedal?
Yes
- Go To 4
No
- Check the Stop Lamp Switch for proper installation and check the related circuits for opens and shorts using the appropriate wiring diagram. If no trouble found, replace the Stop Lamp Switch in accordance with the service information.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST, 3.2L . .
- With the scan tool, read both Stop Lamp Switch statuses while pressing and releasing the Brake Pedal.
- CHECK THE APP SENSORS FOR PROPER OPERATION
- Turn the ignition ON.
- With the scan tool, monitor both APP Sensor voltage readings.
- Slowly press the accelerator pedal from idle until it reaches the end stop near the floor.
- APP Sensor 1 voltage should start at approximately 0.45 volts and increase to approximately 4.6 volts with a smooth transition.
- APP Sensor 2 voltage should start at approximately 0.22 volts and increase to approximately 2.31 volts with a smooth transition.
Does the voltage for the appropriate sensor follow the list specification?
Yes
- Go To 5
No
- Check the Signal and Return circuits for opens and shorts. If no trouble found, Replace the APP Sensor Assembly in accordance with the Service Information. Refer to PEDAL, ACCELERATOR, REMOVAL . After installation is complete, with a scan tool select the ETC RELEARN function to relearn the APPS values.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST, 3.2L . .
- PERFORM THE BRAKE PEDAL CALIBRATION ROUTINE
- With the scan tool, navigate to ABS Module, Misc. Functions, and perform the Brake Pedal Calibration Routine.
Was the Brake Pedal Calibration Routine successful?
Yes
- Test drive the vehicle and verify that the Brake Pedal Calibration fixed the problem.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST, 3.2L . .
No
- Visually inspect the BPP Sensor for Improper installation, damage or mechanical failure. If no trouble found, replace the Brake Pedal Position Sensor.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST, 3.2L . .
- With the scan tool, navigate to ABS Module, Misc. Functions, and perform the Brake Pedal Calibration Routine.
