Driver Side Door Entry Lock Function does not Operate: Description

If the driver door entry unlock function operates normally, but its entry lock function does not, this means that the request code from the driver door is being output normally. In this case, a malfunction in the lock switch circuit (from the certification ECU (smart key ECU assembly) to the front door outside handle assembly (lock switch)) is suspected.
