|Hello. I have a JD6320 and the red coolant warning light, blue warning lights come on along with the gauge going to full hot after 10-12 minutes of operation from cold start. If the ignition key is cycled off and on everything resets for another 10-12 minutes. Have already tested the coolant and intake temp sensors all the way to the ecm, all voltage readings within spec. |
3.6v after 10 min. Even though they tested good, changed both sensors, fault still present. Inputs to ecm same as at sensor. Replaced ECM, fault still present. Note: when new ecm was programmed, JD tech mentioned it was logging a fault code for engine coolant sensor voltage but scanner read 0 fault counts, even with code present. He was puzzled, any ideas?
Ps- I don’t have a wiring schematic for this
