Trailer stability assist light comes on, but does not stay

Customer Question

Trailer stability assist light comes on, but does not stay on, when the light is on sometimes the engine rpm is erratic.
JA: How old is your battery? Have you checked the bulbs?
Customer: Battery just replaces. This problem happened about a moth ago. I took to dealer an they replaced a brake switch. Car ran ok but this problem developed about 2 weeks ago
JA: What is the model/year of your Acura?
Customer: 2012 mdx
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: No, but wondering what it could be
JA: Anything else you think the mechanic should know?
Customer: When they replaced the switch that was all the scan showed
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Acura Mechanic about your situation and then connect you two.

Ok, if you have the fault code that was retrieved when it was scanned, it would help to know it in diagnosing the issue

Sorry, I do not have that. What would cause the engine rpm to fluctuate
Expert:  Eric replied 1 year ago.


RPM fluctuation can be due to a vacuum leak, air intake leak, faulty maf sensor or faulty electronic throttle body
