DTC | B1511 B1512 B1513 B1514 | Driver seat belt switch open/short to Battery Driver seat belt switch short to GND Passenger seat belt switch open/short to Battery Passenger seat belt switch short to GND
CIRCUIT DESCRIPTION INSPECTION PROCEDURE
1. | Preparation
2. | Check buckle switch sensor circuit (Short to GND/Battery). [CHECK] Measure the voltage and resistance of the seat belt switch high and body ground between the SRSCM connector and the seat belt switch connector. Resistance : ∞ Voltage : 0V
3. | Check the seat belt switch [CHECK] Check the resistance with the switch on and off. SWITCH OPEN : R = 4KΩ ± 10% (Belted) SWITCH OPEN : R = 1KΩ ± 10% (Unbelted)
CIRCUIT INSPECTION
DTC | B2500 | Warning lamp failure
CIRCUIT DESCRIPTION INSPECTION PROCEDURE
1. | Check the fuse. [PREPARATION]
A. | Remove airbag fuse and airbag warning lamp fuse from the junction block.
B. | Inspect the state of the fuses.
C. | Replace if necessary.
2. | Check the SRS warning lamp circuit. [PREPARATION]
A. | Connect the negative (-) terminal cable to the battery.
B. | Turn the ignition switch to ON.
[CHECK]
A. | Measure voltage at the harness side connector of the SRSCM. Voltage : 9-16 V
B. | Check the SRS SRI (Service Reminder Indicator). OK : SRS SRI ON
CIRCUIT INSPECTION
DTC | B1620 B1650 B1655 B1657 B1661 | Airbag unit internal failure SRSCM crash recorded Side airbay crash recorded Crash recorded-Belt pretensioner only ECU mismatching
CIRCUIT DESCRIPTION
1. | Functional readiness of the firing circuit activation transistors.
2. | Adequacy of deployment energy reserves.
3. | Safing sensor integrity : detection of faulty closure.
4. | Plausibility of accelerometer signal.
5. | Operation of SRSCM components.
DIAGNOSIS WITH SCAN TOOL
CHECK PROCEDURES
1. | Connect the Hi-Scan Pro DLC to the vehicle's data link connector located under neath the dash panel.
2. | Turn the ignition key to the "ON" position and turn the Hi-Scan Pro ON.
3. | Perform the SRS diagnosis according to the vehicle model configuration.
4. | If a fault code is assured, then replace the component. Never attempt to repair the component.
5. | If the Hi-Scan Pro finds that a component of the system is faulty, there is a possibility that the fault is not in the component, but in SRS wiring or connector.
