1、附录Engine Mechanical and EFI SystemAbstract:The engine block is the main supporting structure to which all other engine parts are attached. Front-suspension system design must provide good ride and stability characteristics. In addition, the front suspension must make provision for turning the front
2、wheels to both right and left for turning cornersKey words: Engine System compartment carThe Cruise Control System allows you to maintain a set speed above 40km/h（25rpm） without keeping your foot on the accelerator pedal.An integral part of the cruise is the over rev. protection circuit. Its functio
3、n is to monitor engine RPM and disengage the cruise control when the clutch is applied or the transmission shift lever is moved in to neutral.When a sudden rise in RPM is detected, the decision to disengage is made for over rev. protection, the blue wire must be attached to the negative side of the
4、ignition coil.For this reason make sure all cruise control wiring is at least 1 ft. away from all electromagnetic sources such as: ignition wires, alternator, regulator, and all high current carrying conductors.To reduce your SET SPEED, press and hold the SET/COAST button. This erases the previous p

Not only can t

It is necessary to release pressure before starting repair work. When installing coolant hoses, route stress-free so that they do not co

The proper grade to be used in your engine depends on existing climatic or seasonal conditions.When inserting the oil dipstick, insert the curved tip of the dipstick

If okay, suspend thermostat and thermometer in a 50/50 mixture of coolant and water. The ECM contains a builtinselfdiagnosis system by which troubles with the engine s

The light goes off automatically when the malfunction has been repaired.A test mode function has been added to the functions of

While performing certain checksit is possible that the ECM will recognize and store a Diagnostic Trouble Code (DTC). Therefore aftercompleting all checks and repairs,check and erase t

Immerse a new clutch disc or brake disc in ATF for at least two hours before assembling them.The most common compound planetary gear sets are the Simpson compound planetary gear set and the Ravigneaux compound planetary gear train.A common type of automatic transaxle or transmission for passenger cars has
