Problem Possible Cause Solutions Unable to clear trouble codes Shuts off when engine automatically turns off in a Hybrid vehicle Poor MPG and Trip Fuel use accuracy When I scan the vehicle, it displays NOT READY Vehicle is not responding to the Clear Codes command Fuel type not set to HYBRID Some sensor initial accuracy not good (especially Diesel) The vehicle has not completed its readiness Tests since the last time it was cleared or the battery was disconnected. Sometimes multiple attempts are needed to clear the codes. You may also try clearing the codes with the vehicle not running, and the key in the on position. Some vehicles don’t respond properly to the Clear Codes command and the codes cannot be cleared by the ScanGauge. Set the fuel type (TYPE) parameter to HYBRID in the Basic Setup Parameters (see page 12), ScanGauge will automatically set the Sleep Event parameter to NO COMM. Use FILLUP procedure to adjust for sensor errors. (see page 31). It will continue to say “NOT READY” until all on board diagnostic tests have been completed. This does not mean that it is not ready to be scanned. To get to this screen the vehicle computer reported that no Trouble Codes exist. Some states require that some or all onboard tests be completed and no Trouble Codes be present to pass emissions testing. When the ScanGauge reports No Codes Found and READY, the vehicle is ready to pass emissions. Some states allow some tests to not be completed and can pass the vehicle even when the ScanGauge reports NOT READY. Trip Fuel use is very inaccurate after using fill-up adjustment Error in adjustment procedure Recalibrate your ScanGauge. See CalibratingYour ScanGauge on pages 20 and 21 54 — www.ScanGauge.com
