– do a diagnostic on a 2007 jeep perfectly

– Working for bmw E36 air bag light ok, no other cable needed. Not sure about e36. It should work if its ob2 vehicle. If there is no airbag reset option means it does not support air bag reset.

– Can read air/fuel ratio or maf or iac readings on a 1996 camaro z28

– Can do a brake bleed on gm vehicles’ and read abs sensor wheel by wheel as far as reading sensor in/ output per wheel yes. But when it comes to bidirectional abs (procedures) for bleeding the system it’s on a vehicle by vehicle bases so I can’t say.

– Can give you the code and what the code means. This scan tool will also allow you to read some voltages coming off of certain sensors. Great scan tool and equivalent to a much more expensive tool.

– Support ABS and Trans modules on some domestic and import vehicles. It is pretty decent on European stuff.

– Can read some VIN number
