What is the P0636 fault code What is the description for the Servo Hydraulic Steering Control Circuit Low Voltage Error? How do you fix the P0636 fault code What are the causes and symptoms of the P0636 error code?
What is the P0636 fault code? What does it signify?
The power steering control circuit is responsible for the OBD-II fault codes (P0635, P0636, and P0637). If the powertrain controller module (PCM), and any related module detects that voltage signals from the power-steering control circuit are too low or not in accordance with vehicle specifications, P0636 will trigger.
The power steering circuit provides the necessary voltage to the various components of the steering system. The PCM monitors the voltage signals coming from the power steering controller sensors and switches. These components enable the power steering system to adjust the fluid pressure. This is essential to avoid damage to power steering components.
To help the steering adapt to different driving conditions and to facilitate steering, the power steering control circuit is connected with the PCM, transmission controller module, cruise control module and anti-lock brake control modules. It continuously sends data. If any one of these modules detects a low incoming voltage signal, P0636 is set.
P0636 fault codes can be found on vehicles that include many models of Suzuki Jeep, Ford Chrysler Dodge Jeep Mini, Mercedes-Benz, Chrysler, Dodge, Chrysler, Dodge and Chrysler.
What causes the P0636 Fault code?
Here are some reasons why P0636 should be set.
- – Corrupted, damaged, melted or corroded cables or connectors
- – Damaged cables or components on the controller area bus (CAN)
- – Defective power steering pressure switching
- – Defective power steering switch
- – Defective power steering controller module
- – A defective power steering motor
- Power steering leaks can cause an insufficient hydraulic level.
- – Blown fuse
- – Clogged or bent hoses
- – Defective PCM
What are the symptoms of P0636 Malfunction Code?
You may experience the following symptoms if your vehicle has the code P0636:
- – Illumination at the check engine lights
- – Steering wheels stiffening and reduced assistance
- – Driving with abnormal sensations
- – When you turn the steering wheel, it makes a strange clicking sound
- – Other related fault codes
How to Fix the P0636 Fault Code
An error code P0636 can be caused when any of the control module’s fail to communicate properly. Other fault codes may be set unnecessarily. You should not have more than one fault code. Instead, focus on the ones that directly relate to Controller Area Network (CAN).
There are several repairs that can resolve the P0636 fault code.
- Repair or replacement of any damaged, disconnected, corroded, or shorted components, cables, and connectors related to the steering systems as necessary
- – Replacing a defective power steering pressure switch
- – Replacing a damaged power steering position switch
- – Replacing blown fuse
- Repairing power steering fluid leakages and topping up hydraulics that are not working
- – Replacing the defective power steering control module
- – Replacing the damaged power steering motor
- – Repair damaged, bent or clogged hoses
- – Replacing CAN wiring harness
- – Replacing the defective PCM
How serious is the P0636 Fault code?
Your driving safety might be at risk if this code isn’t addressed. Even if the vehicle is still driveable, poor steering and handling can pose a danger to you and others. It can cause damage to other parts of the hydraulic system if the code is not addressed. Steering issues require immediate attention and must be dealt with as soon as possible.
