This book shows you how to work on the Transmission Spark Control (T.C.S.) system. From the overview: "This handbook is intended as a guide to check 1972 TOYOTA emission control systems. The first section will show location and identification of emission devices used on each engine series. Tune-up specifications are added for your convenience. The second section is a normal operation test. Following the procedure described in this handbook, you will be able to observe the operation of critical units such as the throttle positioner and distributor vacuum unit. If these units operate in relation to specified road speeds, the T.C.S. system is OK. The third section (testing other-than-normal operation) is a procedure using a test light to isolate a bad T.C.S. unit in the system." With step-by-step instructions, clear pictures, exploded view illustrations, schematics, and specifications, you will have the information you need to get your project on the road and keep it there.
