Circuit Description

WARNING: This page is about a different car, the 2004 Suzuki XL-7 and 2004 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.

When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then, ECM being supplied with the main power, turns ON the malfunction indicator lamp (MIL). When the engine starts to run and no malfunction is detected in the system, MIL goes OFF but if a malfunction was or is detected, MIL remains ON even when the engine is running.
