Fully open ISC valve test
■
Opening the ISC valve fully will raise the engine speed. Do not set the shift
in the F or R position.
This test allows verifying ISC valve opening. With the engine idling in neutral,
voltage is applied (for 2 seconds) to increase the opening of the ISC valve with a
corresponding increase in idle speed.
