Fig. for Step 1, 2, 3 and 4
NOTE:
D When 2 or more codes are indicated, the lowest numbered code will appear first.
D If a code not listed on the table is displayed, then the P/S control module is faulty.
D DTC C1122 (flashing pattern: 22) is indicated when ignition switch ON and engine not running but if
flashing pattern 12 is indicated when engine is started, it means nothing abnormal.
D Current DTC and history DTC can be identified by lighting and flashing of "EPS" light as follows.
"EPS" light after engine
started
"EPS" light when starting
diagnosis switch terminal
and ground terminal
However, if a multiple number of DTC's are set an even one of them is a current DTC, "EPS" light remains
on after engine is started. Therefore, it is not possible to identify any of them as to whether it is a current
one or a history one. (But use of SUZUKI scan tool will make identification possible.)
Current DTC is set.
(Abnormality exists at present.)
Remains ON.
Current DTC is displayed.
