Monitor Strategy Description

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

The ICMD Diagnostic manipulates Air/Fuel ratio and stores the times it takes for the pre and post converter oxygen sensors to switch. It then calculates EWMA values and compares them against calibrated thresholds in order to determine the PASS/FAIL status.
