DTC B1182/19 Short to GND 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 B1182/19 is recorded when a short to ground 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 B1182/19 is not output.
HINT: Codes other than DTC B1182/19 may be output at this time, but they are not related to this check.

Check for intermittent problems
1. CHECK FOR INTERMITTENT PROBLEMS
HINT:
For use of the intelligent tester only:
Inspect the vehicle's ECM using check mode.
Intermittent problems are easier to detect with an
intelligent tester when the ECM is in check mode. In
check mode, the ECM uses 1 trip detection logic, which
is more ...
Diagnosis system
1. CHECK DLC3
The ECU uses ISO 15765-4 for communication.
The terminal arrangement of the DLC3 complies
with SAE J1962 and meets the ISO 15765-4 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition s ...
Repair
1. STEERING OFF CENTER REPAIR PROCEDURE
(a) Inspect steering wheel off center.
(1) Apply masking tape to the top center of the
steering wheel and steering column upper
cover.
(2) Drive the vehicle in a straight line for 100
meters at a constant speed of 35 mph (56 km/
h), and hold the ...
