DTC Detecting Condition and Trouble Area






DTC Confirmation Procedure

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine and shift select lever to "D" range.
4) Start vehicle and increase vehicle speed to 50 km/h (31 mile/h) or more for 2 minutes.
5) Stop vehicle and turn ignition switch OFF.
6) Repeat Step 3) to 5) one time.

DTC Troubleshooting

1.
Was "A/T System Check" performed?
YES -
Go to Step 2.
NO -
Go to A/T System Check A/T System Check.

2.
Do you have SUZUKI scan tool?
YES -
Go to Step 3.
NO -
Go to Step 4.

3. Check transmission range sensor 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 sensor signal ("P", "R", "N", "D", "2" or "L") on display when shifting select lever to each range.

Is applicable range indicated?
YES -
Intermittent trouble. Check for intermittent trouble referring to Intermittent and Poor Connection Inspection Intermittent and Poor Connection Inspection.
NO -
Go to Step 5.

4. Check transmission range sensor circuit for operation

Check without using SUZUKI scan tool:
Turn ignition switch ON.
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?
YES -
Intermittent trouble. Check for intermittent trouble referring to Intermittent and Poor Connection Inspection Intermittent and Poor Connection Inspection.
NO -
Go to Step 5.

5. Check transmission range sensor for installation position

Check transmission range sensor for installation position referring to Transmission Range Sensor Inspection and Adjustment Transmission Range Sensor Inspection and Adjustment.

Is it adjusted correctly?
YES -
Go to Step 6.
NO -
Adjust transmission range sensor and recheck.

6. Check select cable for adjustment

Check select cable for adjustment referring to Adjustments Select Cable Adjustment.

Is it adjusted correctly?
YES -
Go to Step 7.
NO -
Adjust select cable and recheck.

7. Check transmission range sensor

Check transmission range sensor referring to Transmission Range Sensor Inspection and Adjustment Transmission Range Sensor Inspection and Adjustment.

Are check results satisfactory?
YES -
Transmission range sensor circuit open or shorted to ground. If wires and connections are OK, substitute a known-good TCM and recheck.
NO -
Replace transmission range sensor.
