Yeah I’ve been using the diagram attached. After about 12-24hrs with car off, my front wheels finally spin freely. But again, when cars running pressure is built and doesn’t seem to disengage.
The code 31 was from a friends ET-S computer I installed on mine. When the code is present I can not turn at all because my front is locked. My original computer doesn’t give any fault codes and doesn’t lock the front up when driving. I gave up and took it to a mechanic and he thinks it’s the ET-S solenoid. Unfortunately, the complete pump isn’t cheap for a “I think it’s the solenoid”.
