Circuit Description

EBCM is connected to ECM (PCM) through idle up request circuit. During certain ABS events, EBCM will command ECM (PCM) to increase engine idle speed. EBCM sends a 12 V signal on idle up request circuit to ECM (PCM). When idle up request is needed, EBCM will pull voltage low to under 1 V to signal to ECM (PCM) that an increase in idle speed is needed.
