P0588 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The cruise control system controls the speed of your vehicle, it does so, via vacuum. For this the Cruise Control Vent Solenoid releases vacuum if the vehicle has to slow down. If it doesn't perform as requested by the vehicle, then the P0588 code is set. This then automatically disables the cruise control.

The OBD Code P0588 is a common code, so don’t worry about it much. Your vehicles Cruise Control System is controlled by the Powertrain Control Module or PCM and the Cruise Control Module. They both work together in-order to control the speed of your vehicle. The PCM is capable of determining if the vehicles speed is not being controlled as it should, when it notices such malfunction it will automatically run a test on the whole cruise control system. If either of the two (Voltage or resistance reading from the cruise control vent) are deviant from the manufacturer’s settings, the PCM will officially trigger P0588 code.

Have a look at our superior variety of Cruise Control Switch, Body Control Module, cruise control system, Engine Control Module, fuel injection, connectors, blown fuses, straps and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow these two steps:

Step 1 - The first focus to resolve the error code P0588 has to be the cruise control switch. This is located under the steering wheel. In-order to get access to it, you will have to dismantle certain parts, and for this you will need the help of your car’s manual. The manual holds great significance here, because varied models will have different steps to remove parts, and even during assembling them you will need its assistance. Once you have gotten some clarity, that the switch is the issue, you need to purchase a new one and start the dismantling process.

Locate your vehicle's battery and disconnect it, remove the steering wheel column bolt covers (Use a screwdriver/ratchet if needed). With caution, remove the airbag cluster from the center of the steering wheel, for this you will first have to unbolt it from the back of the steering wheel. Detach the electrical connectors connected to the airbag cluster, do this, by simply pressing the side clips and slowly pulling them from the hard-plastic circumference. To get full access to the switch, you will have to completely remove the steering wheel, you may need a special puller for this. Now detach the switch by removing all the bolts holding it to the steering column bracket. You can finally replace it with the new one, and trace back your steps in the opposite direction to put everything back into its place. Again, refer your vehicle manual as much as needed to be sure. After you’ve sorted all that, reconnect the battery, and take your vehicle for a test-drive. Avoid traffic hours for safety reasons.

Step 2 - You will now resolve another very common problem associated with this OBD code, mechanical issues prevailing in the Cruise control Vacuum system. There may be damage to the cruise control vacuum solenoid, or a vacuum leak in the system etc. You will be able to spot them easily upon visual inspection. Repair or replace all the components that are damaged as needed. If there’s a vacuum leak, be sure to fix it right away, as it can lead to terrible issues if not resolved. If you aren’t confident about the locations of the components, and or the diagnostic procedures refer the vehicles manual.

Common Mistakes When Diagnosing the P0588 Code

• A failed and unresponsive Cruise control vent solenoid
• Powertrain Control Module (PCM) has failed to function
• Problematic wiring
