6 button OBC temp not working.

[benfidar]

Hi Folks,

I am trying to track down why my temp does not work. I replaced the thermister in the front bumper. Nothing. I tried to clean the contacts behind the OBC and while fiddling with it, for a fleeting second, the temp appeared, and then returned to what it always says at start up, -30.0C. Ideas?

Connect a variable 10 kOhm resistor between the contact #2 and GND #1, provide +12V to #7 and #5.
The contacts in the connector are numbered:

1 GND            7 Power  
2 Temp Sensor    8
3                9
4                10
5 Ignition Power 11
6                12
