Dodge Durango (HB). Manual - part 992

P2299-BRAKE PEDAL POSITION / ACCELERATOR PEDAL POSITION INCOMPATIBLE (CONTINUED)

For the Engine circuit diagram (Refer to 9 - ENGINE - SCHEMATICS AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
Ignition on. No Break or APPS faults present.

•

Set Condition:
The PCM recognizes a brake application following the APPS showing a fixed pedal opening. Temporary or
permanent. Internally the PCM will reduce throttle opening below driver demand. One trip fault and the code
will be set within 5 seconds. ETC light will illuminate, the light will only stay illuminated while DTC is active.

Possible Causes

CUSTOMER PRESSING ACCLERATOR PEDAL, THEN PRESSING BRAKE PEDAL, AND CONTINUES TO
HOLD THEM DOWN SIMULTANEOUSLY

STOP LAMP SWITCH

APP SENSOR

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).

Diagnostic Test

DTC INFORMATION

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 a scan tool, read DTCs and record the related Freeze Frame data.

Diagnose all other Stop Lamp Switch and APP Sensor codes before continuing.

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 Brake Torquing the engine by pressing
the Accelerator pedal and the pressing 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 9 - ENGINE - STANDARD PROCEDURE)

>> Go To 2

STOP LAMP SWITCH OPERATION

With a 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 3

>> Check the Stop Lamp Switch for proper installation and check the related circuits for opens and shorts

using the appropriate wiring diagram. If OK, replace the Stop Lamp Switch assembly.

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

P2299-BRAKE PEDAL POSITION / ACCELERATOR PEDAL POSITION INCOMPATIBLE (CONTINUED)

APP SENSOR SWEEP

Ignition on, engine not running.

With a scan tool, monitor both APP Sensor voltage readings.

Slowly press the accelerator pedal from idle until it reaches the end stop near the floor.

APPS No.1 voltage should start at approximately 0.45 of a volt and increase to approximately 4.6 volts with a
smooth transition.

APPS No.2 voltage should start at approximately 0.22 of a volt and increase to approximately 2.31 volts with a
smooth transition.

Does the voltage for the appropriate sensor follow the list specification?

Yes

>> Refer to the INTERMITTENT CONDITION Diagnostic Procedure.

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

>> Check the Signal and Return circuits for opens and shorts. If OK, Replace the APP Sensor Assembly

per Service Information. After installation is complete, with a scan tool select the ETC RELEARN func-
tion to relearn the APPS values.

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

For the Engine circuit diagram (Refer to 9 - ENGINE - SCHEMATICS AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
Engine running and battery voltage greater than 10 volts.

•

Set Condition:
If PCM detects that the secondary ignition burn time is incorrect, too short, or not present, an error is detected.
One Trip Fault. Three good trips to turn off the MIL.

Possible Causes

(A955), (K342) ASD RELAY OUTPUT CIRCUIT

(K19) COIL CONTROL NO.1 CIRCUIT OPEN

(K19) COIL CONTROL NO.1 CIRCUIT SHORTED TO GROUND

COIL ON PLUG

PCM

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).

Diagnostic Test

ACTIVE DTC

Ignition on, engine not running.

With a scan tool, read DTCs.

Is the DTC active at this time?

Yes

>> Go To 2

>> Refer to the INTERMITTENT CONDITION Diagnostic Procedure.

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

(A955), (K342) ASD RELAY OUTPUT CIRCUIT

NOTE: The circuit id (K342) is used with the 5.7L engines and the
(A955) id is used with the 3.7L and 4.7L engines.
Turn the ignition off.

Disconnect the Coil on Plug harness connector.

Ignition on, engine not running.

With a scan tool, actuate the ASD Relay.

Using a 12-volt test light connected to ground, probe the (A955),
(K342) ASD Relay Output circuit in the Coil on Plug harness connec-
tor.

Does the test light illuminate brightly?

Yes

>> Go To 3

>> Repair the open or short to ground in the (A955), (K342)

ASD Relay Output circuit between the IPM and Coil har-
ness connector.

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

NOTE: Stop All Actuations.
