DTC Troubleshooting

NOTE:

- When DTC B1513, B1514, B1517 and/or B1531 is detected, check that there is any obstruction in opening range of actuator linkage.
- This flow shows "DTC B1513: Driver Side Temperature Control Actuator (Motor) and/or Its Circuit Malfunction".
- Check "DTC B1514 / B1517 / B1531" in the same manner as "DTC B1513" referring to the following table.





1. Scan tool parameter check

Check "Air Mix Pos Sen (Driver)" using "Data list" mode on SUZUKI scan tool. Scan Tool Testing and Procedures

Is it in good condition?
YES -
Intermittent trouble.
NO -
Go to Step 2.

2. Driver side temperature control actuator circuit check

Disconnect "G20" and driver side temperature control actuator connectors.
Check the following points.
- Resistance of "GRY" and "GRY/BLK" wire circuits: less than 1 ohms
- Resistance of "GRY" and "GRY/BLK" wire circuits between driver side temperature control actuator and ground: infinity

Are they in good condition?
YES -
Go to Step 3.
NO -
Repair or replace defective wire harness.

3. Driver side temperature control actuator check

Check driver side temperature control actuator. Temperature Control Actuator Inspection

Is it in good condition?
YES -
Replace HVAC control module and recheck DTC. HVAC Control Module Removal and Installation
NO -
Replace driver side temperature control actuator. Temperature Control Actuator Removal and Installation
