brakes DODGE RAM SRT-10 2006 Service Repair Manual

For a complete wiring diagramRefer 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 onlystay illuminated while DTC is active.
Possible Causes
CUSTOMER PRESSING ACCLERATOR PEDAL, THEN PRESSING BRAKE PEDAL, AND CONTINUES
HOLDING 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
1.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 toidle. 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?
Ye s>>
Advise the customer of what caused the DTC. This is normal operation of a ETCequipped vehicle
because of safety issues.

POWER STEERING FLOW AND PRESSURE
The following procedure is used to test the operation
of the power steering system on the vehicle. This test
will provide the gallons per minute (GPM) or flow rate
of the power steering pump along with the maximum
relief pressure. Perform test any time a power steering
system problem is present. This test will determine if
the power steering pump or power steering gear is not
functioning properly. The following pressure and flow
test is performed using Power Steering Analyzer Tool
kit 6815 and Adapter Kit 6893.
