Hello, my 2013 LC is having troubles with the combination meter assembly. The instrument gauge will flicker, turn off, reset the trip a / b automatically, and switch "DISP" by itself. It does not respond to ODOT/TRIP reset on the light control rheostat or the DISP button on the steering wheeling. I'm not seeing electrical issues anywhere else in the vehicle.
The following have been tried:
- new battery
- new alternator
- new rheostat
I tried to connect ODB2 and turn on some of the panel lights, such as ECO light, but the software returned a failure that it lost connection. Can anyone confirm whether this should be possible to do?
Also, I used ODB2 interface to display the resistance levels of the rheostat (dimmer) for the instrument panel. It ranged from 0-22%, and the final click moved it to 23%. Is this an appropriate range? I thought I read somewhere that it should range from 0-100. Can anyone confirm how this range behaves on a working unit?
In terms on next steps, I'm thinking of checking the ground points and if those all check out, replace the assembly. When replacing the assembly, do I need to re-program it or is it as simple as plugging it in?
For the ground points, I have not tested them yet. There area few of them related to the combination meter assembly, can anyone comment how difficult each of these are to access?
1) A1 / A2 - Front Fender Apron LH
2) A3 - Front Fender Apron RH
3) C1 - Engine Unit LH
4) E1 - Cowl Side Panel LH
5) E2 - Instrument Panel Brace LH
6) K2 - Quarter Panel LH
And of course, if anyone has any other suggestions / recommendations, I'd love to hear them! Thanks.
