CHECK CODE INSPECTION CHART (CHECK CODE 01)

Check code 01 Buckle switch and passenger sensing system
STEP INSPECTION CONDITION DISPLAY ACTION
1 Unfasten driver-side seat belt. (Buckle switch ON)   Go to the next step.
  Inspect the following parts:
  • Buckle switch (driver-side)
  • SAS control module
  • Wiring harness (Buckle switch (driver-side)-SAS control module)
  Using the DTC and PID of SAS control module, inspect the SAS control module, buckle switch and related wiring harnesses.
  • If there is no malfunction, inspect for the continuity between SAS control module terminal 1X and instrument cluster terminal 2H (wiring harness-side).
    • If there is a continuity, replace the instrument cluster.
2 Fasten driver-side seat belt. (Buckle switch OFF)   Go to the next step.
  Inspect the following parts:
  • Buckle switch (driver-side)
  • SAS control module
  • Wiring harness (Buckle switch (driver-side)-SAS control module)
  Using the DTC and PID of SAS control module, inspect the SAS control module, buckle switch and related wiring harnesses.
  • If there is no malfunction, inspect for the continuity between SAS control module terminal 1X and instrument cluster terminal 2H (wiring harness-side).
    • If there is a continuity, replace the instrument cluster.
3 Seat one person in the passenger's seat, and unfasten passenger-side seat belt. (Seat weight sensor and buckle switch ON)   Go to the next step.
  Inspect the following parts:
  • Buckle switch (passenger-side)
  • Seat weight sensor control module
  • Seat weight sensor
  • SAS control module
  • Wiring harness (Buckle switch (passenger-side)-SAS control module, seat weight sensor-Seat weight sense control module-SAS control module)
  Using the DTC and PID of SAS control module, inspect the SAS control module, buckle switch (driver-side, passenger-side), seat weight sensor control module, seat weight sensor and related wiring harnesses.
  • If there is no malfunction, inspect for the continuity between SAS control module terminal 1X and instrument cluster terminal 2H (wiring harness-side).
    • If there is a continuity, replace the instrument cluster.
 
4 Seat one person in the passenger's seat, and fasten passenger-side seat belt. (Seat weight sensor ON and buckle switch OFF)
Seat no person in the passenger's seat, and unfasten passenger-side seat belt. (Seat weight sensor OFF and buckle switch ON)
Seat no person in the passenger's seat, and fasten passenger-side seat belt. (Seat weight sensor and buckle switch OFF)
  Input signal to the instrument cluster is normal.
  Inspect the following parts:
  • Buckle switch (passenger-side)
  • Seat weight sensor control module
  • Seat weight sensor
  • SAS control module
  • Wiring harness (Buckle switch (passenger-side)-SAS control module, seat weight sensor-Seat weight sense control module-SAS control module)
  Using the DTC and PID of SAS control module, inspect the SAS control module, buckle switch (driver-side, passenger-side), seat weight sensor control module, seat weight sensor and related wiring harnesses.
  • If there is no malfunction, inspect for the continuity between SAS control module terminal 1X and instrument cluster terminal 2H (wiring harness-side).
    • If there is a continuity, replace the instrument cluster.
