CHAPTER 1 SERVICE INFORMATION, WORK ORDERS, AND VEHICLE IDENTIFICATION REVIEW QUESTIONS AND ANSWERS: 1. What is included in the vehicle owner’s manual that could be helpful for a service technician?

(Text Page 2) The most comprehensive and accurate service information is the service information from the vehicle manufacturer.

(Text Page 3) Name and address of the owner with contact information, such as the cell phone number and email address. 4. What should the service technician include on the work order?

(Some engines cannot be determined by the VIN.)
