Circuit Description

DTC will set if engine speed exceeds 5975 RPM while cruise control is engaged. This may occur on slippery pavement, extended wide open throttle acceleration or slipping transaxle. Cruise control disengaging because of these conditions is considered normal. Clear DTC and road test vehicle to verify normal operation.
