![]() ![]() X243 CHECK POWER-TO-FAN(S) CIRCUIT CONTINUITY BETWEEN CCRM AND COOLING FAN(S) If open was only to CCRM pins 1, 2, 6 and 7, after service, GO to X272 (to check both HFC relays in CCRM and Power-To-Fan circuit). If open was to only CCRM pins 3 and 4, after service, GO to X272 (to check both HFC relays in CCRM and Power-To-Fan circuit). If fuse/fuse link is damaged, CHECK B(+) circuit for short to ground before replacing. CHECK condition of related fuses/fuse links.

X241 COOLING FAN WILL NOT OPERATE AT ANY SPEED: COMMAND FAN ON (HIGH SPEED FOR TWO SPEED APPLICATIONS) AND CHECK FOR VOLTAGE AT FAN Ĭooling fan will not operate at any speed. ĭuring the operational check of both fan speeds, did the fan operate at any speed? Note: For the proper results of these pinpoint tests, no fault DTCs must have been present during EEC-V Quick Test.įor one speed fan applications (Mustang), GO directly to X241. ![]() ![]() X240 ELECTRIC COOLING FAN CONCERN: DID THE FAN OPERATE AT ANY SPEED?
