DTC Troubleshooting
Step
1
Was "A/T System Check" performed?
2
Do you have SUZUKI scan tool?
3
Check transmission range sensor (switch) circuit for
operation
Check by using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition switch
OFF.
2) Turn ignition switch ON and check transmission range
sensor signal ("P", "R", "N", "D", "2" or "L") on display
when shifting select lever to each range.
Is applicable range indicated?
4
Check transmission range sensor (switch) circuit for
operation
Check without using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals "E93-1", "E93-7", "E93-8",
"E93-18", "E93-19" and "E93-20" respectively with select
lever shifted to each range.
Taking terminal "E93-1" as an example, is battery
voltage will be indicated only when shift lever is shifted to
"R" range and 0 V for other ranges as shown in table.
Check voltage at other terminals likewise, referring to
table.
Are check results satisfactory?
5
Check transmission range sensor (switch) for
installation position
1) Check transmission range sensor (switch) for installation
position referring to "Transmission Range Sensor
Inspection and Adjustment".
Is it adjusted correctly?
6
