1998 Pontiac Grand Am 2.4L Build date 7/97
VIN 1G2NE52T3WC700733
Verdict (10.4.4) wouldn't communicate with engine control module but would read codes and communicate with ABS, Air Bag, and VTS sytems. Checked power inputs and grounds to ECM, ok. Grabbed OTC scanner and had communications with ECM. Used verdict and selected multiple years 96,97,98, and 1999 grand ams. Verdict communicated with ECM when selected under a 1999 Grand Am but wouldn't communicate with other modules when under a 1999 grand am. ECM data seemed accurate when compared to OTC Data loaded to a 1998 grand am Just wondering if anyone else has seen this issue. Just thought i would let Snap-On know of this issue. Thanks
