P056A OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P056A can be defined as Cruise Control Increase Distance Signal. It is the cruise control system which keeps the vehicle running at a constant speed until a signal cancelling this fixed speed would be received. Now if the main switch is turned on with the vehicle in the running mode, engine control module would be applied with the battery voltage. When a signal from the control switch is input to the ECM while the vehicle is in a state, the ECM controls fuel injection to make a car move at a steady stable as per you want.

When the system is working, "CRUISE" indicator lamp in the meter assembly would start illuminating. It is the ECM which would monitor the cruise control increase distance signal and would set up the P056A error code when the cruise control increase distance Switch would not be as per the parameters set by the manufacturer.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P056A error code. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

What causes this problem with the Cruise Control Increase Distance Signal?

• Faults in the cruise control switch or buttons which are within the switch
• No proper or effective electrical connection being made by the connectors
• The wires which are within the cruise control harness might be defective
• Cruise control switch assembly might be contaminated with fluid
• Malfunctioning ECM
• Defaults in the cruise control module
• Issues related to body control module
• Overheated parts might cause problems

Here are some steps which you should follow in order to diagnose this fault code:

Step 1 - First of all, you must visually inspect the cruise control switch/module. There can be some situations where the buttons are missing, cola has stuck the button in one position, and buttons are loose and not making proper electrical connections. That is the reason why you must make sure that the buttons, that control the cruise functions, are freely moving and not contaminated with potentially damaging particles and/or dirt. Also make sure to record all of the cruise functions' malfunctions or abnormalities.

Step 2 - Is your cruise control light coming on in the instrument cluster when cruise is manually activated? If not, you may want to check if there is a fuse for the circuit. This information should be found in the make and model service manual. If there are any blown fuses then they should be replaced with new and manufacturer-approved ones.

Step 3 - You can access the harness to the cruise control switch/module, generally speaking by removing some dash parts (i.e. steering column shroud, airbag module in steering wheel, etc.). To pinpoint the specific wire involved in the fault, you will definitely require a proper wiring harness for your vehicle. These differ significantly, given a lot of reasons. Always acquire proper service information before accomplishing anything too invasive.

Step 4 - It would be a great idea to make sure your anti-lock brakes system is in good working condition and no ABS light on in the dash. A lot of sensors are used in the ABS including speed sensors that, if malfunctioning, could fool the computers into thinking the vehicle is going faster or slower than the real speed.
