Since this DTC is provided for engineering, it may be detected when no actual failure exists. (1) Even if no failure is detected, it may be stored depending on the battery condition or voltage for starting an engine. (2) It is stored when 180 sec. has passed after the power supply connector is pulled out after engine start. (3) It may be stored when the engine key is turned again after engine start. (4) It may be stored when the engine key is turned 1 min. again after engine start. - Logical address: 21 (Switch)LOGICAL ADDRESS - 21 (SWITCH)
