I just had this exact same problem on my 2016 CRV. I had a start that took longer than normal (maybe 5 long seconds), and those 3 lights came on. TPMS, Power Steering, Traction Control. I can't verify TPMS or Traction Control, but power steering seems to be totally fine. Did you find a resolution to this? Every subsequent start has been fine, and nothing seems obviously wrong with the car while driving.
Yes I did!
Sorry for forgetting about this thread. I got my diagnosis from Honda. My VSA Modulator had gone bad. For those unaware, this is the hydraulic block that controls the individual/paired sets of brakes. It is what controls the pulsing of the brakes during ABS events or brakes individual wheels during stability/Traction control events. One or more of the solenoids/sensors in my Modulator had become faulty. Honda's only recommendation was to replace the Modulator. Deep breath here: $1900 for the job, they quoted. The Modulator alone was either 1100 or 1300, and the rest was labor. And the part is on backorder for months, I'm told.
Long story short, I found a much better solution.
Module rebuilds for darn near everything: ABS Modules, Climate Control Modules, Instrument Clusters, Power Accessories, Powertrain modules and more.
This small company in Idaho rebuilds these modules for tons of makes and models. A new Modulator was 1100-1300; Module Master rebuilt mine for $250, and it's absolutely flawless. Codes are gone, brakes are perfect. It even has a five year warranty.
There are some major logistics to work out with this job. To start, you have to send your Modulator to module master. They can't sell you one ahead and have you swap/return (see side note at the bottom). That means for all the time it takes to remove it, ship it out, repair it, ship it back, and reinstall, your car is entirely disabled with no brakes. So here's how I did mine:
I was determined to get this done as quickly as possible, but speed costs money. I found a local shop that was willing to remove it, push the car out of the building and park it, and give me the part to ship out. I paid about $150 to FedEx the part in 2 days to Module master (had to get it there before a holiday weekend). I paid MM 250 for the repair, plus $75 more to do a one-day turnaround on the repair (standard is five days), and then another $80 for them to next-day-air the part directly back to the shop doing the swap. The shop got the part back and reinstalled it same day. It is VERY easy for any shop that regularly does brake work to swap this part, at least on my 2014 Accord. It's easily accessible. They only charged my 1.5 hours of labor and a bottle of fluid to bleed the brakes. The actual job of swapping the part was only $164. My grand total for absolutely everything involved with this repair was about $900 IIRC, and more than $300 of that was paying for rushed shipping and rushing the repair at MM. And I would happily do that again. Module Master literally saved me more than $1000 by doing the rebuild. I can't sing their praises loud enough.
Side note: if you buy a new Modulator, or find one in a scrap yard, I'm told it will require a special programming job to render it compatible with your car, which can only be done at a dealership. More money, more time. With Module Master rebuilding your same unit, NO REPROGRAMMING IS REQUIRED. Seriously, get it done through MM. I was able to borrow my dad's truck for the days while my car was out of service (five days total even with all the rushing), so you'll have to work out your own logistics on that.
Hope this helps!
