Constant Control Relay Module

Constant Control Relay Module (CCRM), located on left side of engine compartment, is a solid-state electronic unit using a combination of relays and solid state switched to control operation of A/C compressor clutch, cooling fan, fuel pump and PCM. See Figure. PCM can interrupt A/C compressor operation through CCRM during engine start-up, Wide Open Throttle (WOT), low engine idle conditions or excessively high temperatures. For additional CCRM information and testing, see ELECTRIC COOLING FANS, EEC-V - ALL MODELS article.
