jimz Posted August 5, 2011 Share Posted August 5, 2011 my granite started acting up with goofy coolant temp gauge actions, gauge would get to about 140 then drop off, fan would engage and then stay on, now none of the gauges work and am getting "no info" on display. Checked wires and grounds and still have the same issue....any ideas anyone?? AI-427 engine......

jimz Posted August 5, 2011 Author Share Posted August 5, 2011 BTW..if I disconnect batteries then reconnect them the gauges will sweep then go back to no response. Also, when I turn key off the "no info" display disappears and then the hours and miles will show until the delay relay turns off....

MasterTech Posted September 5, 2011 Share Posted September 5, 2011 Sounds like a possible data link issue. Is the fault light (lightening bolt) on?
