[Mitch Leis]

I was driving my land cruiser 2Fe..then I fell into a ditch..my car went down to low position..ever since then the AHC is not working well..I tried changing the all 4 suspensions bug I haven't bleeded. When the car starts..tbe fluid is like pumped out of the system and it overflows on the reservoir..What should I do???

Pictures or video would be very helpful.

Do you have access to a laptop with Techstream? Or any other device that can read AHC pressures (not just a simple OBD2 scanner)?

Do a visual check to see if your height sensors got bent, broken, disconnected, etc. If you know how suspensions normally look, they will be the one part that looks like it doesn't really belong in the mix (like it may not be doing anything to help with the suspension function).

My suggestion is just a visual check to see if something got mangled, and because of this causing the AHC computer to react accordingly.

The sure-fire solution to understand the current status of your AHC system is to read the values from the AHC computer with a tool like Techstream. You can also read the error codes, if there are any error codes stored.

Posting this data will surely help the AHC gurus on here diagnose, troubleshoot, and hopefully fix your AHC issues.

This will not answer your question directly, but after I watched this video, all of the mystery was gone from the AHC YotaMD AHC Overview. Very helpful.
