Abstract

A skip shift device performance detecting method used to more accurately enable skip shift diagnostic execution in a manual transmission equipped vehicle where a skip shift has been requested and a transmission clutch remains engaged. Where a skip shift request ceases during clutch engagement, a timed loop is used to monitor if clutch disengagement occurs before the loop times out. Where clutch disengagement occurs before the loop times out, skip shift diagnostic execution is enabled. Where the loop times out before disengagement, skip shift diagnostic execution is disabled. Where the skip shift is requested and the clutch remains engaged, the skip shift request is monitored to determine whether it is withdrawn before clutch disengagement. If it is withdrawn before clutch disengagement, the aforementioned timed monitoring loop is executed. If it is not withdrawn before clutch disengagement, execution of the skip shift diagnostic is enabled.
