Inspection Of ECM And Its Circuits: Notes

WARNING: This page is about a different car, the 2006 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.

ECM and its circuits can be checked by measuring voltage, pulse signal and resistance with special tool connected.

CAUTION: ECM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to ECM with ECM connectors disconnected from it.
