2014 grand caravan T harness

Question

I installed a 2014 grand caravan with evo all T harness and compustar cm 800. after programming, I can lock and unlock. but I tried many times to learn tach but failed. I changed seting from tachless to tach in starter brain. connection I made are +12v parkling light and ground. ignition and +12v connected in harness according  to the diagram. D2D mode.  the light was correct when programming.

I read cm800 install manual again. it says it support idata protocol. is that the means that  cm800 doesn't support fortin 2 way d2d mode? it can tell evo all of door lock and unlock. but doesn't read foot brake and tach stauts?

Answer 1

what is the service number of your evo? if the protocol is not correct the resulting signals sent from the evo may not be interpreted correctly by the cm800. You have to match the evo to the default setting of the cm800.

Answer 2

Set your compustar to ADS datalink protocol and then set the EVO-ALL datalink option to, F2- AP-OFA datalink.

The only remote starters i have seen offer only 1-way datalink is a localy sold Autostart brand.

Answer 3

Leave your CM800 datalink protocol by default and enable option F2 in your EVOALL.
