Intermittent Simulation

WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2003 Toyota Tundra, 2003 Toyota Tacoma, 2003 Toyota Sienna, 2003 Toyota Sequoia, and 2003 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

To reproduce the conditions creating an intermittent fault, use the following methods:

Lightly vibrate component. See VIBRATION METHOD .
Heat component. See HEATING METHOD .
Wiggle or bend wiring harness. See VIBRATION METHOD .
Spray component with water. See WATER APPLICATION METHOD .

Monitor circuit/component voltage or resistance while simulating intermittent. If engine is running, monitor for diagnostic trouble codes. Use test results to identify a faulty component or circuit.
