DTC B1180/17 Short in Driver Side Squib 2nd Step Circuit
DESCRIPTION
The driver side squib 2nd step circuit consists of the center airbag sensor assembly, the spiral cable and the steering pad.
The circuit instructs the SRS to deploy when deployment conditions are met.
DTC B1180/17 is recorded when a short circuit is detected in the driver side squib 2nd step circuit.

INSPECTION PROCEDURE
HINT:
1 CHECK STEERING PAD (DRIVER SIDE SQUIB 2ND STEP)
CAUTION: Never connect a tester to the steering pad (driver side squib 2nd step) for measurement, as this may lead to a serious injury due to airbag deployment.
NOTICE: Do not forcibly insert the SST into the terminals of the connector when connecting.
Insert the SST straight into the terminals of the connector.
SST 09843-18060
OK: DTC B1180/17 is not output. HINT: Codes other than DTC B1180/17 may be output at this time, but they are not related to this check.
Go to step 2
REPLACE STEERING PAD
2 CHECK CONNECTORS
OK: The lock button is not disengaged, and the claw of the lock is not deformed or damaged.
REPLACE SPIRAL CABLE
3 CHECK DRIVER SIDE SQUIB 2ND STEP CIRCUIT
Standard resistance
Go to step 5
4 CHECK CENTER AIRBAG SENSOR ASSEMBLY
OK: DTC B1180/17 is not output.
HINT: Codes other than DTC B1180/17 may be output at this time, but they are not related to this check.
REPLACE CENTER AIRBAG SENSOR ASSEMBLY
USE SIMULATION METHOD TO CHECK
5 CHECK INSTRUMENT PANEL WIRE
HINT: The activation prevention mechanism of connector "B" has already been released.
Standard resistance
REPAIR OR REPLACE INSTRUMENT PANEL WIRE
6 CHECK SPIRAL CABLE
Standard resistance
REPLACE SPIRAL CABLE

Correct use of the seat belts
Extend the shoulder belt so that
it comes fully over the shoulder,
but does not come into contact
with the neck or slide off the
shoulder.
Position the lap belt as low as
possible over the hips.
Adjust the position of the seatback.
Sit up straight and well
back in the seat.

Control Module Performance
DESCRIPTION
The ECM continuously monitors its main and sub CPUs. This self-check ensures
that the ECM is
functioning properly. If outputs from the CPUs are different and deviate from
the standards, the ECM will
illuminate the MIL and set a DTC immediately.
The ECM also monitors the cru ...
Voice Recognition Difficulty
INSPECTION PROCEDURE
1 CHECK CONDITION
Check if the system's voice recognition level is low by
using only one particular voice.
OK:
System's voice recognition level is low with any
voice.
2 CHECK MAP DISC
Check that the map disc is not deformed or cracked.
OK:
No deformation ...
