DTC TROUBLESHOOTING CHART

Step	Action	YES	NO
1	Was "A/T System Check" performed?	Go to Step 2.	Go to A/T SYSTEM CHECK .
2	Do you have SUZUKI scan tool?	Go to Step 3.	Go to Step 4.
3	Check transmission range sensor (switch) circuit for operation Check by using SUZUKI scan tool: Connect SUZUKI scan tool to DLC with ignition switch OFF. Turn ignition switch ON and check transmission range signal ("P", "R", "N", "D", "2" or "L") on display when shifting select lever to each range. Is applicable range indicated?	Intermittent trouble. Check for intermittent referring to INTERMITTENT AND POOR CONNECTION INSPECTION .	Go to Step 5.
4	Check transmission range sensor (switch) circuit for operation Check by not using SUZUKI scan tool: Turn ignition switch ON. Check voltage at terminals "G07-1", "G07-2", "G07-8", "G07-9", "G07-20" and "G07-21" respectively with select lever shifted to each range. Taking terminal "G07-21" as an example, is battery voltage will be indicated only when select lever is shifted to "2" range and 0 V for other ranges as shown in table. Check voltage at other terminals likewise, referring to table. Are check results satisfactory?	Intermittent trouble. Check for intermittent referring to INTERMITTENT AND POOR CONNECTION INSPECTION .	Go to Step 5.
5	Check transmission range sensor (switch) circuit for operation Check transmission range sensor (switch) referring to TRANSMISSION RANGE SENSOR (SHIFT SWITCH) INSPECTION AND ADJUSTMENT . Are check results satisfactory?	"WHT/BLK", "RED", "WHT/RED", "YEL/RED", "YEL" or "RED/BLU" circuit shorted to power circuit or shorted each other. If wires are OK, substitute a know-good TCM and recheck.	Replace Transmission range sensor.
