Intermittent Simulation

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Lexus SC 430, 2002 Lexus RX 300, 2002 Lexus LX 470, 2002 Lexus LS 430, and 2002 Lexus IS 300. 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 SPRINKLING METHOD .
Remove vacuum from component.
Apply vacuum to component. Monitor circuit/component voltage or resistance while simulating intermittent. If engine is running, monitor for Diagnostic Trouble Codes (DTCs). Use test results to identify a faulty component or circuit.
