Constant Control Relay Module (CCRM)

Faults in CCRM or circuit should set a diagnostic trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (2.3L) article in the ENGINE PERFORMANCE section. If diagnostic trouble code has not been set, see CIRCUIT TEST X in TESTS W/CODES - EEC-IV (2.3L) article in the ENGINE PERFORMANCE section for CCRM testing.
