What codes if any?

 

CO273 and U0073

 

C0273- verify that there is appropriate power and ground to the ABS assembly.
See alldata.com or similar for wiring schematic/voltage specs.
Let us know what the power/ground measurements are.

U0073- believe this is set as result of C0272.

2009 Camry gauges/dash lights issue, AC stops, WTF mode

I have had a 2009 Camry LE since Oct 2008 and now just recently started having trouble with it. A couple of days ago while driving I noticed that all the warning dash lights (ABS, maintenance light, brake, tire) would light up and the speedometer, engine heat gauge, and RPM gauge would all go...

I would advise the old school Toyota "wiggle" test. So start the car and then have someone wiggle and tap on the connector and the brake control module. If this happened with 2 of them the original and the replacement in short order I suspect the harness or connector. You have to remember we are dealing with a CAN bus so anything that disrupts communication between the dash, the abs module and the main engine control unit will make crazy things happen!

If it is just a bad connector you can always find a way to keep tension on it. That connector has more pins that an Amish Quilt Party so I would imagine it rarely gets replaced and is expensive prob. an entire harness.

So at any rate do the wiggle test first!
