NOTE:

•There are five types of OBD system on ECM depending on the vehicle specification. For identification, refer to OBD System Description:K14C.
•There are two types of OBD system on TCM depending on the vehicle specification. For identification, refer to OBD System Description.
•In case that MIL turns on, the malfunction(s) is detected in either ECM or TCM (type A-A/T model in Section 5A) and it stores the trouble information (DTC, freeze frame data, etc.) in its memory.

1)Set ignition “OFF”.

2)Connect SUZUKI scan tool or CAN communication OBD-II generic scan tool (type A, C, D and E) to DLC (1).
