DTC Will Set when
The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring and connector
terminal contact is above a spec ified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in contact coil and driver air bag (inflator) module or the others.
Step 2: Check driver air bag (inflator) module initiator circuit. (in instrument panel and floor harness)
Step 3: Check driver air bag (inflator) module initiator circuit. (in floor harness)
Step 4: Check whether malfunction is in contact coil or driver air bag (inflator) module.
DTC Troubleshooting
Step Action Yes No 1 1) With ignition switch OFF, disconnect contact coil connector located under of the steering column.
2) Check proper connection to contact coil at terminal in “G26” connector.
3) If OK, then connect special tools (B) and (C) to “G26” connector disconnected in Step 1).
