DTC Troubleshooting: Notes

DTC P0705 TROUBLESHOOTING CHART

Step Action YES NO
1  Was "CVT System Check" performed?  Go to Step 2. Go to CVT SYSTEM CHECK .
2  Do you have SUZUKI scan tool?  Go to Step 3. Go to Step 4.
3  Transmission range sensor circuit check for operation using SUZUKI scan tool 
  1. Turn off ignition switch and connect SUZUKI scan tool to DLC.
  2. Turn ignition switch to ON position and check transmission range signal ("P", "R", "N", "D") on scan tool display when shifting select lever to each range.

Is applicable range indicated? 		 Check for intermittent trouble. See INTERMITTENT AND POOR CONNECTION INSPECTION Go to Step 5.
4  Transmission range sensor circuit check for operation not using SUZUKI scan tool 
  1. Turn ignition switch to ON position.
  2. Check that voltage between each transmission range sensor circuit and vehicle body ground respectively with select lever shifted to each range. Taking transmission range sensor ("D" range) circuit as an example, is battery voltage indicated only when select lever is shifted to "D" range and 0 V for other ranges as shown in the Table for Step 4 .

Check voltage at other circuits likewise.
Are check results satisfactory? 		 Check for intermittent trouble. See INTERMITTENT AND POOR CONNECTION INSPECTION Go to Step 5.
5  Select cable adjustment check 
  1. Check select cable for adjustment. See Select Cable Adjustment 

Is it adjusted correctly? 		 Go to Step 6. Adjust select cable and recheck.
6  Transmission range sensor adjustment check 
  1. Check transmission range sensor for adjustment. See Transmission Range Sensor Inspection and Adjustment 

Is it adjusted correctly? 		 Go to Step 7. Adjust transmission range sensor and recheck.
7  Transmission range sensor circuit check 
  1. Turn off ignition switch and disconnect connectors from transmission range sensor and TCM.
  2. Check for proper terminal connection to transmission range sensor and TCM connectors.
  3. If connections are OK, check that transmission range sensor circuit (A1 - A4) is as follows.
    • Insulation resistance of wire harness is infinity between transmission range sensor circuit terminal and each terminal at transmission range sensor connector.
    • Circuit voltage of each transmission range sensor circuit is 0 - 1 V with ignition switch in ON position.
    • Wiring harness resistance of each transmission range sensor circuit is less than 3 Ω.
    • Insulation resistance between each transmission range sensor circuit and vehicle body ground is infinity.

Are they in good condition? 		 Go to Step 8. Repair or replace defective wire harness.
8  Transmission range sensor check 
  1. Check transmission range sensor. See Transmission Range Sensor Inspection and Adjustment 

Is it in good condition? 		 Substitute a known-good TCM and recheck. Replace transmission range sensor. See Transmission Range Sensor Removal and Installation
