NOTE:
D
For “
l
” marked No. in DTC column, engine is hard to start unless DTC is cleared from ECM memory.
D
For (
) marked No. in DTC column, it is indicated when generic scan tool is used.
D
DTC DRIVING CYCLE column indicates the number of driving cycle before DTC is stored in ECM memory.
D
For (
) marked item in DTC DRIVING CYCLE column, it is the number of driving cycle used for generic
scan tool.
D
For “
n
” marked No. in DTC column, ignore this DTC though it may be indicated on Suzuki scan tool. It
dose not affect engine and emission control system.
