Inspection Procedure

PREPARATION
Refer to PREPARATION OF INSPECTION .
CHECK BPT RESISTANCE
CAUTION: Never attempt to measure the circuit resistance of the airbag module (squib) with an ohmmeter.
1. Connect the Dummy and the Dummy Adapter on BPT harness connector.
  - Refer to " GENERAL INFORMATION - RESTRAINT " for the SST No. of Dummy and Dummy Adapter.
2. Measure resistance between the terminal 39 (37) and 40 (38) of SRSCM harness connector.
  Specification (resistance) : 1.4 ~ 4.5 Ω

3. Is the measured resistance within specification?
  YES
  - Replace the Seat Belt Pretensioner (BPT) module.
  NO
  - Check open circuit.
CHECK OPEN CIRCUIT
1. Measure resistance between the terminal 2 of BPT harness connector and the terminal 40 (38) of SRSCM harness connector.
2. Measure resistance between the terminal 1 of BPT harness connector and the terminal 39 (37) of SRSCM harness connector.
  Specification (resistance) : below 1 Ω

3. Is the measured resistance within specification?
  YES
  - Check short circuit.
  NO
  - Repair or replace the wiring harness between the BPT and the SRSCM.
CHECK SHORT CIRCUIT
1. Measure resistance between the terminal 1 and 2 of BPT harness connector.
  Specification (resistance) : infinite

2. Is the measured resistance within specification?
  YES
  - Go to next step.
  NO
  - Repair or replace the wiring harness between the BPT and the SRSCM.
