INSPECTION
STEPACTIONYESNO
1Perform diagnostic trouble code check. Is there any DTC
(including code No.12, NO CODES on SUZUKI scan
tool) exists?Go to step 2.Go to step 3.
2Is malfunction DTC (other than code No.12) exists at step
1?Go to step 7 of ABS
diagnostic flow table
in this section.Go to step 3.
31) Disconnect ABS hydraulic unit / control module
connector. (See Fig. 1)
2) Check for proper connection to ABS hydraulic
unit / control module connector at terminals ªA17º,
ªA25º and ªA10º.
3) If OK, turn ignition switch ªONº and measure
voltage at terminal ªA25º of connector.
Is it 10 ± 14 V?Go to step 4.ªB / Wº circuit open.
41) With ABS control module connector disconnected,
turn ignition switch ON and light ABS warning lamp.
2) Connect terminal ªA17º of disconnected connector to
ground using service wire.
Does ªABS warning lampº turn off?Go to step 5.ªBl / Oº circuit open.
If wire and
connection are OK,
replace ABS lamp
driver module.
51) Measure resistance from connector terminal ªA10º
to body ground.
Is continuity indicated?Substitute a
known-good ABS
hydraulic unit /
control module
assembly and
recheck.ªBº circuit open.

AUTOMATIC GEAR SHIFT DIAGRAM
Automatic shift schedule as a result of shift control is shown below. In case that select lever is shifted to L at a higher
than 52 km / h or 33 mile / h speed for G16 engine (45 km / h or 28 mile / h for J20 engine, 55 km / h or 34 mile / h for
H25 engine), 2nd or 3rd gear is operated and then down shifts to 1st at a speed lower than that. No up shift is
available in L.
The same as, the select lever is shifted to 2 at a higher than 102 km/h (64 mile/h) speed for G16/J20 engines (105
km / h or 65 mile / h for H25 engine), 3rd gear is operated and then down shifts to 2nd at a speed lower than that.
