My rear air suspension is not working at all on my 2014 Sequoia. The rear is sitting really low and the man light is yellow and flashing. The Toyota dealership says the ECU is not communicating with that system, so they want to replace the ECU for 1800.00, but can't guarantee that will fix the problem. The car has 70,000 miles. Does this sound like I need a new ECU? Are there other, smaller, things that can be ruled out first?
What makes this problem better or worse?
