DTC 46 Driver Pretensioner Loop Short To Voltage
D09RW014
Circuit Description:
When the ignition switch is turned “ON”, the SDM will
perform tests to diagnose critical malfunctions within
itself. Upon passing these tests, “Ignition 1”, and
pretensioner loop voltages are measured to ensure they
are within their respective normal voltage ranges.
The SDM monitors the voltage at “Driver Belt Low”
terminal “22” and “Passenger Belt Low” terminal “10” to
detect shorts to B+ in the pretensioner assembly circuits.
DTC Will Set When:
“Ignition 1” is in the normal operating voltage range. This
test is run once each ignition cycle and “Continuous
monitoring”. Once these conditions are met and the
voltage at “Driver Belt Low” is above a specified value,
DTC 46 will set.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp and sets
DTC 46.
DTC Will Clear When:
The malfunction is no longer occurring and the ignition is
turned “OFF”.
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the SDM is
malfunctioning.
3. This test isolates the malfunction to one side of the
driver pretensioner assembly yellow 2–pin
connector at the base of the driver seat.
4. This test determines whether the malfunction is in
IB13–BLU/RED.
5. This test determines whether the malfunction is in
IB14–BLU/YEL.
Diagnostic Aids:
An intermittent condition is likely to be caused by a short
to B+ in the driver pretensioner assembly circuit. Inspect
IB13–BLU/RED and IB14–BLU/YEL carefully for cutting
or chafing. If the wiring pigtail of the driver pretensioner
assembly is damaged, the components must be
replaced. A careful inspection of IB13–BLU/RED and
IB14–BLU/YEL, including the driver pretensioner
assembly is essential to ensure that the replacement
SDM will not be damaged.

DTC 52 Pretensioner Deployment Event Commanded
D09RW014
Circuit Description:
The SDM contains a sensing device which converts
vehicle velocity changes to an electrical signal. The
electrical signal generated is processed by the SDM and
then compared to a value stored in memory. When the
generated signal exceeds the stored value, the SDM will
cause current to flow through the pretensioner assembly
deploying the pretensioners and causing DTC 52 to set.
DTC Will Set When:
The SDM detects a frontal crash, up to 30 degrees off the
centerline of the vehicle, of sufficient force to warrant
deployment of the air bags and pretensioner seat belt.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp records
“Crash Data”, and sets a diagnostic trouble code.
DTC Will Clear When:
The SDM is replaced.
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. If pretensioner assembly (s) has not deployed, DTC
52 may have falsely set.
3. If DTC 52 has set with no signs of frontal impact, the
diagnostic trouble code has falsely set.

Installation
1. Place the clutch coil assembly (1) on the front head
with the terminals positioned at the "marked" location.
2. Place the J-33024 clutch coil installer over the
internal opening of the clutch coil housing and align
installer with the compressor front head.
3. Center the J-8433-1 puller crossbar in the counter-
sunk center hole of the J-33024 clutch coil installer.
Install the J-33026 through bolts and washers
through the crossbar slots and thread them into the
holding fixture J-33026 to full fixture thickness.
4. Turn the center forcing screw of J-8433-1 puller
crossbar to force the clutch coil onto the front head.
Be sure clutch coil and J-33024 installer stay "in-
line" during installation.
5. When coil is fully seated on the front head, use a
1/8 in diameter drift punch (2) and stake the front
head at three places 120 degrees apart, to ensure
clutch coil (3) remains in position.
Stake size should be only one-half the area of the
punch tip and be only approximately 0.28–0.35
mm (.010–.015 in) deep.
Legend
(1) Stake Front Head 0.28–0.35 mm Deep
(0.10–015 in)
(2) Clutch Coil Housing

6. Install rotor and bearing assembly and the clutch
plate and hub assembly as described previously.

7. Remove and discard the seal seat O-ring (2) from the
compressor neck using O-ring remover J-9553-01.
8. Recheck the shaft and inside of the compressor
neck for dirt or foreign material and be sure these
areas are perfectly clean before installing new parts.
Cleaning
Thoroughly clean O-ring seal groove in front head.
CAUTION: Seals should not be re-used. Always use
a new specification service seal on rebuild. Be sure
that the seal to be installed is not scratched or
damaged in anyway. Make sure that the seal seat
and seal are free of lint and dirt that could damage
the seal surface or prevent sealing.
Installation
1. Dip the new seal seat O-ring (1) in clean 525
viscosity refrigerant oil and assemble onto O-ring
installer J-33011.2. Insert the O-ring installer J-33011 into the
compressor neck until the installer "bottoms". Lower
the moveable slide of the O-ring installer to release
the O-ring into the seal O-ring lower groove (The
compressor neck top groove is for the shaft seal
retainer ring.) Rotate the installer to seat the O-ring
and remove the installer.
3. Dip the new seal in clean 525 viscosity refrigerant oil
and assemble seal to Seal Installer J-23128-A, by
turning handle clockwise. The stamped steel case
side of the lip seal must be engaged with knurled
tangs of installer so that flared-out side of lip seal is
facing and installed towards the compressor. Install
seal protector J-34614, in the seal lip and place over
the compressor shaft, and push the seal in place with
a rotary motion or place the seal protector J-34614
over end of compressor shaft, and slide the new seal
onto the shaft with a rotary motion until it stops. Take
care not to dislodge the O-ring. Be sure the seal (2)
makes good contact with the O-ring. Disengage the
installer from the seal and remove the installer
J-23128-A and the seal protector J-34614.
CAUTION: Handling and care of seal protector is
important. If seal protector is nicked or the bottom
flared, the new seal may be damaged during
installation.
4. Install the new seal retainer ring with its flat side
against the Seal, using Snap-Ring Pliers. Use the
sleeve from O-ring installer J-33011 to press in on
the seal retainer ring so that it snaps into its groove.
5. To leak test, install compressor leak test fixture
J-39893 on rear head of compressor and connect
gage charging lines and Refrigerant Recovery
System. Pressurize suction and high-side of
compressor with R-134a Refrigerant. Temporarily
install (M9
1.25 thread on shaft) nut and, with the
compressor in horizontal position, rotate the
compressor shaft in normal direction of rotation
several times by hand. Leak test the seal area and
correct and leak found. Recover the refrigerant.
Remove shaft nut.
