HINT:
-
"Hybrid Battery Cooling Fan 1 Frequency" is detected when the battery cooling blower assembly is operating and its value changes in proportion to the battery cooling blower assembly speed.
-
If the battery cooling blower assembly speed is excessively high, this DTC is stored.
MONITOR DESCRIPTION
If the hybrid vehicle control ECU detects that the speed of the battery cooling blower assembly is higher than the target speed, it will illuminate the MIL and store a DTC.
