As you mat know the purge valve is located on the atmosphere side of the throttle valve so there is no vacuum. Instead this vehicle has a small vacuum located on the intake manifold to draw vapors out of the canister. My question is, shouldn't the pump be commanded on during this test ? As you can see in the screen shot it is not being commanded on. The puge valve and vent vent valve are being commanded and are operational, without vacuum though the test is a mute point. Is this a snap on error or a GM oversight. The code I had was P0446 and was a plugged or stuck vent valve which I replaced and solved the problem. Just wondering about the purge and seal test.

I either need a new screen complete with protector or just a protector if it’s possible?

any help on where to get one greatly appreciated.

This month’s highlights include:


• SEAT® Leon Heater Matrix Restriction Faults
• Toyota® Avensis No-Start Fuel Pump Drive Issues

Our latest Snap-on® software highlight is now live, focusing on SRS systems and the importance of IMU calibration following repairs.

Modern restraint systems rely on precise sensor data, meaning module replacement, removal, or repositioning can require recalibration to restore the correct system reference point and ensure proper operation.



This latest software update expands SRS special-function coverage with Volvo® XC90 IMU calibration support, helping technicians complete post-repair procedures correctly using guided workflows built directly into the tool.



The article also takes a deeper look at:


• Why IMU calibration matters
• Common causes of persistent SRS warning lights
• Post-repair verification procedures
• Safety-critical SRS system operation

It has worked great until very recently, the screen I... start up screen and is now locked or frozen on that screen. None of the buttons will let me enter or change information. Anyone have any ideas on what may be required. This is a great scope and love to get it working again as we do work on a lot of pre 2000 vehicles. ]]> US Member User Group Geotl https://productforum.autorepairdata.com/forum/member-general-discussion-forum/general-discussions/us-member-user-group/158726-mt1665-snapon-oscilloscope
