Manual Description
Most intermittent malfunctions are caused by poor electrical connections or wiring. In this case, careful checking of suspicious circuits may help prevent the replacement of good parts. A visual check only may not find the cause of the malfunction, so a road test should be performed.
Through the talks with the customer, find out what symptoms are present and under what conditions they occur. It is also important to use the diagnosis sheet to understand what type of trouble the customer is having. When there is fluid leaking or seeping from a fluid connection, use a clean cloth to wipe off the fluid and recheck for leaks.
D For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals. If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal. As a result, there may be times when acceleration is slightly less than usual for the same accelerator pedal operation.
