RESTRAINT CONTROL SYSTEM 9A1-55

DTC Will Clear When
The ignition switch is turned “LOCK”.

DTC Will Set When
The combined resistance of the driver pretensioner
assembly, harness wiring circuits “Driver Pretensioner
High” and “Driver Pretensioner Low”, and connector
terminal contact is above a specified value. This test
run once each ignition cycle during the “Resistance
Measurement Test” when:
1. No “higher priority faults” are detected during “Turn–
ON”
2. “Ignition 1” voltage is in the specified value.

Action Taken
SRS control unit turns “ON” the “AIR BAG” warning
lamp and sets DTC B0042.

DTC Chart Test Description
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the malfunction is in
the SRS control unit.
3. This test verifies proper connection of the yello
w
connector at the base of the driver seat.
4. This test checks for proper contact and/or corrosion
of the connector terminals at the base of the drive
r
seat.
5. This test isolate the malfunction to one side of the
SRS coil assembly yellow connector located at the
base of the driver seat.
6. This test determines whether the malfunction is due
to high resistance in the wiring.
7. This test determines whether the malfunction is in
the driver pretensioner assembly.

Diagnostic Aids

An intermittent condition is likely to be caused by a poor
connection at the drive pretensioner harness connecto
r
terminals “1” and “2”, SRS control unit terminals “8” and
“7”, or a poor wire to terminal connection in circuit
“Driver Pretensioner High” or “Driver Pretensioner Low”
The test for this diagnostic trouble code is only run while
the “AIR BAG” warning lamp is performing the bulb
check. W hen a scan tool “Clear Codes” command is
issued and the malfunction is still present, the DTC will
not reappear until the next ignition cycle.

11A-24 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
DTC B0003
Description
When the ignition switch is ON, the ICU begins
authentication of the transponder key in the steering
lock through the antenna coil. Once the ICU transmits a
signal, the transponder must send back a specific
response signal. If the ICU never receives a response
signal from the transponder, this DTC will set.
Condition for Running the DTC • The ignition switch is ON.
Condition for Setting the DTC • The ICU does not receive a response signal from the transponder key.
Action Taken When the DTC Sets • The engine will fail to run if the fault occurs before starting the engine. Condition for Clearing the DTC
• A current DTC clears once ignition cycle has occurred without the fault recurring.
• A history DTC will clear after 50 consecutive ignition cycles, if the condition for malfunction is no
longer present.
• Use a scan tool to clear the DTC.
Diagnostic Aids • Electromagnetic interference may affect intermittent condition.
• An antenna coil problem may set this DTC.
• Objects that block transponder key in the steering lock may set this DTC.
• Another key that is attached to the key ring may affect this DTC to set.
• If the ignition switch has been turned ON without transponder key this DTC sets.
