This comprehensive ASE L1 test preparation program is a must have study tool before taking the ASE L1 Advanced Engine Performance Specialist test.

Automotive Video, Inc.'s  L1 Test Prep program will assess your knowledge for diagnosis and repair of computer-controlled engine systems. The ASE L1 test will also help ASE mechanics in diagnosing the cause of high-emission failures. This is especially important in states where basic I/M (inspection/maintenance), enhanced I/M (ASM or IM240), and OBD testing programs are in effect.

Dave Hobbs and Jim Wilson both relate the composite vehicle to situations that ASE technicians encounter on a daily basis with advanced OBDII systems. Part one covers general engine system diagnosis, computerized powertrain controls diagnosis and ignition system diagnosis. This 3.5 hour DVD video section also covers fuel and air induction system diagnosis and repair, emission control system failures and I/M failure diagnosis.  The second part of this program consists of a 65 question ASE L1 practice test. The ASE L1 practice test is followed by a detailed explanation and discussion of the correct and incorrect answers that tells you why the answers are right or wrong. This section also includes a complete glossary of OBDII trouble codes, useful for any ASE mechanic.
