Side Air Bag (SAB) Connector Replacement
Side Air Bag (SAB) Connector Replacement
NOTE:
Use connector replacement kit -- P/N 24009-CM71A (one kit per connector/seat).
1. Attach a personal ground strap to your wrist and a ground point on the vehicle.
^ Keep the ground strap attached during the entire connector replacement process.
NOTE:
Personal ground straps are available at local electronic supply stores.
41
2. Position the SAB connector and harness so you have ample working room.
3. Disconnect the SAB connector.
NOTE:
The SAB harness side (seat side) end will be replaced first.
42
4. Remove / pull off the corrugated cover end (see Figures CR4 and CR5).
5. Cut / split the side of the corrugated cover and remove it to expose the SAB wires.
^ Cut enough to expose 165 mm (6-1/2 inches) of the SAB wires.
CAUTION:
Do not damage the SAB wires.
6. Measure 150 mm (6 inches) from the back side of the SAB connector.
43
7. Install the shorting pin at the 150 mm (6 inch) point (see Figure CR7 to CR10).
NOTE:
The shorting pin is included in the connector replacement kit.
WARNING:
Make sure the shorting pin is securely installed before cutting the harness wires. The shorting pin will prevent unintended air bag
deployment from static electricity.
a. Align the harness wires with the slits in the shorting pin as shown in Figure CR8 and CR9.
CAUTION:
Damage to the harness may occur if the wires are not aligned with the slits.
Align the harness wires with the slits in the shorting pin as shown.
44
b. Use pliers to securely attach the shorting pin to the harness.
8. Cut the SAB harness wires 60 mm (2-3/8 inches) from the back side of the SAB connector (see Figure CR11).
9. Strip about 10 mm of insulation from the ends of the SAB harness wires.
10. Slide solder sleeve connector onto the SAB harness wires as shown in Figure CR13.
NOTE:
^ Solder sleeve connectors are included in the connector replacement kit.
^ When the shorting pin is removed these solder sleeve connectors will be used to cover the pierced insulation.
45
11. Cut the wires on the new SAB connector 60 mm (2-3/8 inches) from the back side of the connector (see Figure CR14).
NOTE:
^ Make sure you are prepping the SAB side (seat side) of the SAB connector (male end).
^ The wire length of the new connector must match the cut of wire length of the old connector.
12. Strip about 10 mm of insulation from the wire ends of the new connector.
13. Slide solder sleeve connectors onto the connector wires as show in Figure CR15.
NOTE:
Solder sleeve connectors are included in the connector replacement kit.
14. Twist the wires of the new SAB connector together with the wires of the SAB harness as shown in Figure CR16.
NOTE:
46
There is no need to match wires. It does not matter which wire from the harness is connected to which wire from the connector.
15. Slide the solder sleeve connectors from the connector side over the twisted wires (see Figure CR16).
16. Attach the new connector using the solder sleeve connectors (refer to Instructions for Using Solder Sleeve Connectors shown below).
NOTE:
It is recommended that you read all of the instructions for using solder sleeve connectors shown below before starting.
Instructions for Using Solder Sleeve Connectors
A. Securely twist together the wires that will be connected / soldered.
B. Position the Solder Sleeve Connector so that the solder ring (in the connector) is centered around the exposed twisted wire area.
WARNING:
Do not use an electric type soldering tool. An electric type soldering tool may generate a current that may activate the SAB.
47
C. Use the special Flameless Heat Gun - J-46538 to heat the solder sleeve connector.
This operation will:
^ Melt the solder (silver ring inside the solder sleeve connector) into the exposed twisted wire area.
^ Melt the sealant (red rings inside solder sleeve connector) onto the wires.
^ Shrink the plastic sleeve onto the wires.
Important Soldering Tips:
^ Position the solder sleeve connector in the middle of the heat shield of the Heat Gun.
^ Start heating the connector from the center and move back and forth (side to side) and around to allow even distribution of the heat
to the entire connector.
^ Make sure the solder completely flows into the exposed twisted wires and the adhesive properly seals the wire insulation to the
connector sleeve. Stop applying the heat immediately after this happens.
WARNING:
^ The Flameless Heat Gun and the solder sleeve connectors become HOT during the soldering process.
^ Allow the gun and connectors to cool before handling them.
CAUTION:
Be careful not to damage the connector or wires with the heat gun:
^ Do not apply heat for more than about 40 seconds.
^ Do not overheat the connector or wires (i.e., severe darkening of connector sleeve or wire insulation).
17. Once the wires are attached with the solder sleeve connectors, remove the shorting pin.
NOTE:
48
When the shorting pin is removed there will be exposed wires at the point of the pierced insulation. The additional solder sleeve
connectors will be used to cover these exposed wires.
18. Slide the additional solder sleeve connectors over the exposed wires (see Figures CR21 and CR22).
19. Apply the solder sleeve connectors.
^ Position the solder part of the connector over the exposed wires.
^ Use the special Flameless Heat Gun-J-46538 to heat the solder sleeve connector.
^ Refer to Important Soldering Tips below.
Important Soldering Tips:
^ Position the solder connector in the middle of the heat shield of the Heat Gun.
^ Start heating the connector from the center and move back and forth (side to side) and around to allow even distribution of the heat to the
entire connector.
^ Make sure the adhesive properly seals the wire insulation to the connector sleeve. Stop applying the heat immediately after this happens.
WARNING:
^ The Flameless Heat Gun and the Solder Connectors become HOT during the soldering process.
^ Allow the Gun and connectors to cool down before handling them.
CAUTION:
Be careful not to damage the connector or wires with the heat gun:
^ Do NOT apply heat for more than about 40 seconds.
^ Do NOT overheat the connector or wires (i.e., severe darkening of connector sleeve or wire insulation).
49
20. Install a new corrugate cover over the SAB wires.
NOTE:
New corrugated cover is supplied with the connector replacement kit.
21. Apply electrical tape to the corrugated cover and wires as shown.
^ As you wrap, keep the tape tight to the harness.
^ Over-lap the tape 50% as you wrap.
Replacement of the body side connector end
22. Cut / remove the plastic covering from the body side harness wires.
50
^ Cut enough to expose 75 mm (3 inches) of the wires.
23. Cut the wires 60 mm (2-3/8 inches) from the back side of the connector as shown in Figure CR26.
24. Strip about 10 mm of insulation from the ends of the body side harness wires.
25. Cut the wires on the new body side connector end 60 mm (2-3/8 inches) from the back side of the connector as shown in Figure CR28.
NOTE:
^ Make sure you are prepping the body side connector (female end).
^ The wire length of the new connector must match the cut of wire length of the old connector.
26. Strip about 10 mm of insulation from the wire ends.
51
27. Install solder sleeve connectors on the wires as show in Figure CR29.
NOTE:
Solder sleeve connectors are included in the connector replacement kit.
28. Twist the wires of the new connector together with the wires of the harness.
NOTE:
There is no need to match wires. It does not matter which wire from the harness is connected to which wire from the connector.
29. Slide the solder sleeve connectors over the connectors twisted wires (see Figure CR30).
30. Attach the new connector using the solder sleeve connectors (refer to Instructions for Using Solder Sleeve Connectors.
31. Cover the wires with a corrugated cover.
52
^ Cut the corrugated cover to the correct length.
NOTE:
Corrugated cover is included in the connector replacement kit.
32. Apply electrical tape to the corrugated cover and wires as shown.
