RESTRAINT CONTROL 9A1-51

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 is
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 B0064.

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

DTC Chart Test Description
Number(s) below refer to circled 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 yellow
connector at the base of the driver seat.
4.
This test checks for proper operation of the shorting
clip in the yellow connector.
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 shortening in the wiring.
7.
This test determines whether the malfunction is in
the driver pretensionerassembly.

Diagnostic Aids
An intermittent condition is likely to be caused by a short
between circuit “Driver Pretensioner High” or “Driver
Pretensioner Low” or a malfunctioning shorting clip on
the driver pretensioner assembly which would require
replacement of the component. The test for this
diagnostic trouble code is only run while the “AIR BAG”
warning lamp is performing the bulb check. When a
scan tool “Clear Codes” command is issued and the
malfunction is still present, the DTC will not reappear
until the next ignition cycle.

DTC B0065 (Flash Code 65) Driver Pretensioner Squib Circuit High
Resistance


RTW49JLF000101

Circuit Description
When the ignition switch is turned “ON”, the SRS
control unit will perform tests to diagnose critical
malfunctions within itself. Upon passing these tests,
“Ignition 1”, and deployment loop voltages are
measured to ensure they are within their respective
normal voltage ranges.
The SRS control unit then proceeds with the
“Resistance Measurement Test” “Driver Pretensioner
Low” terminal “41” is grounded through a current sink
and the driver current source connected to “Drive
r
Pretensioner High” terminal “42” allows a known
amount of current to flow. By monitoring the voltage
difference between “Driver Pretensioner High” and
“Driver Pretensioner Low”, the SRS control unit
calculates the combined resistance of the drive
r
pretensioner assembly, SRS coil assembly, harness
wiring circuits “Driver Pretensioner High” and “Drive
r
Pretensioner Low” and connector terminal contact.

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 “42”
and “41”, or a poor wire to terminal connection in circuit
“Driver Pretensioner High” or “Driver Pretensioner Low”
