My ScanGauge will shutdown while driving in my Dodge/Chrysler/Jeep

Some Dodge/Chrysler/Jeeps are sensitive about how fast/slow information is requested from the ECU. If it’s too fast/slow the ECU will sometimes stop responding to the ScanGauge’s requests for information, so the ScanGauge thinks the vehicle is no longer running and turns off to save power.

Setting the update rate on the ScanGauge to Fast or Slow can sometimes solve this issue and allow the ScanGauge to operate normally.

Some gauges are blank
Trip Fuel use is very inaccurate after using fill-up adjustment
When I scan the vehicle, it displays NOT READY
Unable to clear trouble codes
Poor MPG and Trip Fuel use accuracy
ScanGauge connects and then goes to sleep after 10 to 15 seconds
ScanGauge never stops saying “Connecting…”
Nothing displayed and no backlight
Shuts off when engine automatically turns off in a hybrid vehicle
