In the 2nd through the 4th frames, the freeze frame data of each
malfunction is stored in the order as the malfunction is detected.
These data are not updated.
Shown in the table below are examples of how freeze frame data
are stored when two or more malfunctions are detected.
Freeze Frame Data Clearance :
The freeze frame data is cleared at the same time as clearance of
diagnostic trouble code (DTC).
DATA LINK CONNECTOR (DLC)
DLC (1) is in compliance with SAEJ1962 in its installation posi-
tion, the shape of connector and pin assignment.
Serial data line (K line of ISO 9141) (3) is used for SUZUKI scan
tool or generic scan tool to communicate with ECM, TCM, Air Bag
SDM and ABS control module.
SUZUKI serial data line (6) is used for SUZUKI scan tool to com-
municate with immobilizer control module.FRAME
