Are you testing it on bench or in the vehicle?

 

[sam wildcat]

In the van when I put the plug into the display unit it shows up the temp and the heater starts up but then display goes blank and heater stops

Can measure supply voltage when control module is plugged in and plugged out?

 

[sam wildcat]

12 v in or out

 

[Robert]

Measure voltage on your 20 pin plug (terminals 19 & 20) and see what the voltage readings are when it is plugged in and plugged out.

 

[sam wildcat]

Is that the thick red and brown wires if so I get 12v on and off display

 

[Robert]

Yes red and brown.
What voltage readings are you getting on these 2 wires when the plug is in the unit and out of the unit?

 

[sam wildcat]

12 volts

 

[sam wildcat]

If I put my meter only in the red wire and the other lead to earth I get 12volts if I only put my meter on brown wire and other to earth I get no reading on meter . if meter in red and brown same time I get 12volts

 

[Robert]

What voltage readings are you getting between red and brown wires when the plug is in the unit and out of the unit?
