B Reprogram the TIPM using wiTECH1. Disconnect the negative battery cable.
2. Open the Totally Integrated Power Module (TIPM) cover and disconnect the large red B+ wire from the TIPM (Figure 2).
3. Disconnect the TIPM assembly from its mounting bracket by compressing the four retaining tabs and pulling straight upward. This will allow access to the wiring connectors located on the bottom side of the TIPM (Figure 2 and 3)
4. Connect the brown with white tracer wire and brown with orange tracer wire from the overlay wiring harness to the brown TIPM connector wiring harness using the following procedure:
a. Disconnect the brown TIPM electrical connector from the
TIPM by first pressing down the center lock tab, and at the same time lifting the gray lock handle and then pulling on the connector body (Figure 4).
b. Remove the electrical tape from the brown connector wiring harness.
c. Remove the black plastic cover from the backside of the brown connector (Figure 5).
d. Locate the brown wire (with white tracer) and the brown wire (with orange tracer). These wires are located next to each other in the connector (Figure 6).
CAUTION:
There are two brown wires (with white tracer) located in this
connector. Be sure to find the brown (with white tracer) wire that is located next to the brown (with orange tracer) wire (Figure 6).
e. Cut the brown (with white tracer) wire and the brown (with orange tracer) wire approximately 2 inches down from the brown connector (Figure 6).
f. Place a piece of shrink tube over each of the wire ends (connector side) so that the wire is halfway into the shrink tube (Figure 7).
g. Using a heat gun, heat the shrink tube until it fits tight against the wire and glue comes out of the end of the shrink tube (Figure 7).
h. Install the black plastic cover onto the backside of the brown connector (Figure 5).
i. Using electrical tape, tape the two wires that were sealed with shrink tube to the brown connector wiring harness. These two wires from the brown connector will no longer be used.
j. Remove approximately 1/2 inch of insulation from the end of the brown wire (with white tracer) and brown wire (with orange tracer) (wiring harness side) that were cut in Step 4e.
k. Remove the pre-stripped insulation from the overlay wiring harness brown wire (with white tracer) and brown wire (with orange tracer).
l. Slide one piece of heat shrink tube onto the brown (with white tracer) wire and one piece of heat shrink tube onto the brown (with orange tracer) wire.
m. Using wire splice crimp tool (P/N 10042) and a brass crimp, crimp the brown wire (with white tracer) from the vehicle wiring harness to the brown wire (with white tracer) from the overlay wiring harness (Figure 8).
n. Using wire splice crimp tool (P/N 10042) and a brass crimp, crimp the brown wire (with orange tracer) from the vehicle wiring harness to the brown wire (with orange tracer) from the overlay wiring harness (Figure 8).
o. Using a soldering gun, apply solder to both brass crimps installed in Steps 4m and 4n (Figure 9).
CAUTION:
Use only rosin core solder.
p. Slide the heat shrink tube over the soldered brass crimp on each wire.
q. Using a heat gun, heat the shrink tube until it fits tight against the wire and glue comes out of the end of the shrink tube.
5. Install the red wire from the overlay wiring harness into the green TIPM connector using the following procedure:
a. Carefully disconnect the green TIPM connector from the TIPM by sliding the red lock tab towards the TIPM, then unlatch the gray lock bar and pull on the connector body (Figure 10).
b. Remove the electrical tape from the vehicle wiring harness leading up to the green TIPM connector.
c. Remove the black plastic wire cover from the back of the green TIPM connector (Figure 11).
d. Pull out the red terminal lock, located in the green TIPM connector, approximately 1/4 inch to disengage the terminal lock feature (Figure 11).
e. Install the red wire terminal from the overlay wiring harness into cavity 26 of the green TIPM connector (Figure 12).
CAUTION:
Do not force the terminal into the connector. It is keyed and
will only install in one direction.
f. Snap the red connector lock back into the green TIPM connector (Figure 11).
g. Install the black plastic wire cover onto the back of the green TIPM connector and apply electrical tape to the harness as required.
6. Install the pink wire and dark green wire from the overlay wiring harness into the black TIPM connector using the following procedure:
a. Carefully disconnect the black connector by unlatching the gray lock bar and pulling on the connector body (Figure 13).
b. Remove the electrical tape from the black TIPM connector wiring harness.
c. Push the edges of the lock bar outward slightly and close the lock bar to gain access to the back cover retaining tabs (Figure 14).
d. Disengage the connector back cover from the black TIPM connector. Carefully slide the back cover up the wiring harness about two inches to gain access to the break out plugs located on the backside of the connector back cover (Figure 15).
e. Using a small pair of needle nose pliers, carefully break out the plugs in location 35 and 42 (Figure 16).
f. Slide the connector back cover down the wires and snap it into place on the backside of the black TIPM connector (Figure 15).
CAUTION:
Be sure not to kink or fold over any of the wires when
sliding the connector back cover into place.
g. Partially pull out the red terminal lock in the black TIPM connector about 1/4 inch.
h. Carefully insert the dark green wire from the overlay wiring harness into cavity 35 (Figure 17).
CAUTION:
Do not force the terminal into the connector. It is keyed and
will only install in one direction.
i. Carefully insert the pink wire from the overlay wiring harness into cavity 42 (Figure 17).
CAUTION:
Do not force the terminal into the connector. It is keyed and will only install in one direction.
j. Push the red terminal lock into the connector to lock the terminals.
k. Apply electrical tape around the black TIPM connector wiring.
7. Install and lock all removed electrical connectors into the TIPM.
8. Install the TIPM into its mounting bracket.
9. Open the TIPM cover and connect the B+ terminal (Figure 18). Tighten the B+ nut to 210 in. lbs. (23 N.m).
10. Remove and discard fuse J20 (pink 30 amp) from the TIPM (Figure 18). Refer to the inside of the TIPM cover to verify fuse location.
11. Close the TIPM cover.
12. Install the "J" nut onto the relay bracket (Figure 19).
13. Connect the new relays and bracket assembly to the overlay wiring
harness connectors.
NOTE:
Both relays are the same and can be plugged into either overlay wiring harness connector.
14. Install the relay bracket and ground wire from the overlay wiring harness using the supplied bolt into the existing hole on the left fender apron (Figure 20). Tighten the bolt to 195 in. lbs. (22 N.m).
15. Carefully bend the relay bracket so that the relays are point downward approximately 45 degrees (Figure 20).
16. Connect the negative battery cable.
17. Continue with Section B to reprogram the TIPM with wiTECH, Section C to reprogram the TIPM with StarSCAN or Section D to reprogram the TIPM
with StarMOBILE.
NOTE:
The TIPM must be reprogrammed before the windshield wipers will
operate.
B. Install TIPM Wiper Relay and Overlay Wiring Harness
CAUTION:
The TIPM may not support "abort - recovery" mode. If this flash
process is interrupted/aborted and you are unable to read the TIPM Flash Part Number, the TIPM may be damaged beyond repair and may require
replacement. Always verify if the module has truly been damaged beyond
repair by attempting to restart the flash process.
1. Open the hood. Install a battery charger and verify that the charging rate provides 13.2 to 13.5 volts. Do not allow the charger to time out during the flash process. Set the battery charger timer (if so equipped) to continuous charge.
NOTE:
Use an accurate stand-alone voltmeter. The battery charger
voltmeter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.
2. Connect the wiPOD to the vehicle data link connector.
3. Place the ignition key in the "RUN" position.
4. Launch the wiTECH diagnostic application.
5. Select "TIPMCGW" from the vehicle view screen.
6. Select the "FLASH" tab.
7. Select the flash file from the list.
8. Select the "UPDATE" button and follow the screen prompts.
9. Clear all DTC's.
NOTE:
Due to the CCN programming procedure, DTC(s) may be set in
other modules (PCM, TCM, ABS, BCM, MIC, WCM, etc.) within the
vehicle, if so equipped. Some DTC's may cause the MIL to illuminate.
10. Verify windshield wiper operation.
11. Continue with Section E. Calibrate "Auto-Up" Front Windows.
