B1707
DTC B1707 PASSENGER BUCKLE PRETENSIONER RESISTANCE LOWDESCRIPTION
This system decides whether the seat belt of the driver is locked and then prevent the belt pretensioner from deploying on crash.
The above DTC is recorded when a resistance too high is detected in the buckle switch circuit.
Detecting Condition:
DETECTING CONDITION
SPECIFICATIONS
Resistance(BUPT) : 1.5 ≤ R ≤ 5.7 Ohm
INSPECTION OF CONNECTOR AND TERMINAL
1. Check all the connectors related to the DTC for contact condition visually.
2. Check the connector and the terminal.
1. Check the connector for connection securely.
2. Check the terminal for contact condition, deterioration,erosion and elasticity.
CAUTION: Do not deform the connector for revising contact.
3. Are confirmed trouble on the connector and the terminal?
YES - After repairing the trouble part, check whether DTC occurs or not.
NO - Check the buckle pretensioner resistance.
CHECK BUCKLE PRETENSIONER RESISTANCE
1. Preparation
1. Disconnect the negative(-) terminal cable from the battery,and wait 30 seconds.
2. Remove the DAB module.
3. Disconnect the connector of the PAB, SAB, CAB, SIS, FIS and BPT,
4. Disconnect the SRSCM connector.
2. Check buckle pretensioner resistance. Check the buckle pretensioner resistance.
Resistance(BUPT) : 1.5 ≤ R ≤ 5.7 Ohm
YES - From the result of the above inspection, the malfunctioning part can now be considered normal.
NO - Replace the buckle pretensioner.
