If you want to easily diagnose this P0637 fault code, then all you have to do is to follow the steps which are mentioned below:

• For diagnosing this error code P0637 you will need to research the technical service bulletins, also known as the TSB’s. Make sure TSB’s are specific to your vehicle make and model. Believe us this will help you save a lot of time and help you achieve right troubleshooting goals. After you get hold of the TSB’s next step is to look for the power steering fluid level and check for any leaks and damages. Keep one thing in mind that the right fluid level plays a crucial role in the circuit functioning.
• Check all the parts within the circuit visually to check for any wiring defects (short, open, bare wires). After this, next step is to check and make sure that all the connectors are operating well, i.e. they are not damaged or corroded. This will also include checking for the Controller Area Network, abbreviated as CAN for any wiring damage.
• The additional steps are particular to every vehicle make and model. To perform these steps, you will need a digital multimeter and particular technical references for the vehicle. In order to check the voltage, you need to know that voltage requirements will also vary depending upon your specific make and model year. Also, power steering controllers, pressure switches and position sensors have different voltage requirements to function efficiently. In case you discover lack of absence of power source or ground then continue your test to check the integrity of the wiring, connectors and other related components. Keep in mind that the tests should be performed while removing the power from the circuit and normal readings for the wiring and connectors. It should be 0 ohms of resistance. In case you come across resistance or no continuity, be sure that it is an indication of faulty wiring that is open or shorted and must be repaired or replaced

Common Mistakes When Diagnosing the P0637 Code

You can avoid any misdiagnosis if you make sure that if you receive multiple trouble code then you should focus on the ones first that are related to CAN and after that move on to others. Also, make use of a specialized scanner to highlight the control module issues accurately and efficiently. Most common error that you are likely to commit is to fail to follow the obd-ii diagnosis protocol. It is really essential to follow the protocol precisely step by step. Keep a close check on all the common code that precede this error code P0637 to avoid any misdiagnosis.
