Hello and thank you for using Just answer! I'm Billy and i will assist you with this. Feel free to ask if further info is needed.

Billy :

P1955: Glow plug control module 2 (J703) to PCM communication circuit, range / performance

Billy :

This basically means that there is a problem with the wiring......

Billy :

You should check the wiring connectors at control units (engine, and glow plug units)........these should be in engine compartment just behind headlight........

Billy :

Check these connectors....and others for any loose.....water ingress, non insulated wires......

Billy :

And make sure you have clean and tight battery cable contacts, and engine ground cable.

Billy :

Thank you for trusting JA and myself.......get back to me if further info is needed.....positive feedback and bonuses appreciated...
