Seat Belt Pretensioner: Symptom Related Diagnostic Procedures
22 - Airbag Module and ELR W/Pretensioner (LH/RH) Inflated.
DIAGNOSIS: Front airbag module and ELR with pretensioner (LH/RH) are inflated.
CAUTION: Before performing diagnostics on airbag system, turn ignition switch "OFF", disconnect battery ground terminal, and then wait at least 20
seconds.
5G1: CHECK IF TROUBLE CODE 22 IS INDICATED
Confirm flashing trouble code according to "BASIC DIAGNOSTICS PROCEDURE".
CHECK: Is airbag warning light trouble code 22 indicated?
YES:
Replace airbag control module, front sub sensor , front airbag module of both sides and ELR with pretensioner of both sides.
NO:
Perform clear memory.
61 - ELR W/ Pretensioner (RH) Circuit Open, Shorted, Short/GND
DIAGNOSIS:
-
ELR with pretensioner (RH) circuit is open, shorted or shorted to ground.
-
Airbag control module is faulty.
CAUTION: Before performing diagnostics on airbag system, turn ignition switch "OFF", disconnect battery ground cable and then wait at least 20
seconds.
5V1: ELR WITH PRETENSIONER INSPECTION
1. Disconnect connector (AB26) from ELR with pretensioner RH side , and connect (AB26) to test harness F connector (1F).
2. Connect airbag resistor to test harness F connector (3F).
3. Connect battery ground cable and then turn ignition switch to ON (engine off). Observe airbag warning light.
CHE4K: Does the airbag warning light come on for about 7 seconds, then go out and stay out?
YES:
Replace ELR with pretensioner RH side.
NO:
Go to step 5V2.
5V2: SIDE AIRBAG HARNESS OPEN CIRCUIT INSPECTION
1. Turn ignition switch OFF, disconnect battery ground cable and then wait at least 20 seconds.
2. Disconnect side airbag connector RH side (AB24) and (AB25). (Side airbag equipped vehicle)
3. Disconnect connector (AB18) from airbag control module , and connect (AB18) to test harness I or I2 connector (1I).
4. Measure resistance across test harness I or I2 connector (3I) terminal and test harness F connector (3F) terminal.
CHECK: Is the resistance less than 10 ohms?
YES:
Go to step 5V3.
NO:
Replace side airbag harness.
