Condition Code: b4

Service Procedure
1. Check the IPMA for software updates using the latest software level of the FDRS scan tool. Is there a software update available for the IPMA?
1. Yes - download and run the "IPMA – Image Processing Module A (IPMA) Software Update" app. Proceed to Step 2.
2. No - proceed to Step 3
2. Did the software update correct the condition?
1. Yes - repair is complete.

2. No - proceed to Step 3
3. Are DTCs C1001:31 and/or U3000:89 stored in the IPMA or were recently stored in the vehicle's 60-Day vehicle health alert/ DTChistory?
NOTE: The vehicle's 60-Day vehicle health alert/DTC history (if applicable) can be found in the PTS > Connected Vehicle > Connected Vehicle Home.
1. Yes - inspect the coaxial cables between the IPMA and the IPMA camera for loose connections. Perform wiggle test to check connectors C900 and
C9128 for being loose. If no loose connections are present, proceed to Step 4. If loose connections are present, reconnect and proceed to Step 5.
2. No - proceed to Step 30.
4. Power the vehicle on and wait 30 seconds. Clear and retrieve DTCs. Are C1001:31 and/or U3000:89 present in the IPMA?
1. Yes - proceed to Step 6.
2. No - the issue is intermittent. Replace both sections of coaxial cable running from the IPMA camera to the IPMA following Steps 6-17 and Steps 19-28,
then proceeding to Step 29.
5. Power the vehicle on and wait 30 seconds. Clear and retrieve DTCs. Are C1001:31 and/or U3000:89 present in the IPMA?
1. Yes - proceed to Step 6.
2. No - proceed to Step 30.
6. Replace the coaxial cable running from the IPMA camera to C900 at the left A-Pillar by overlaying the new coaxial cable next to the existing coaxial cable and cutting
off the existing coaxial cable connectors. To do so, begin by removing the left A-Pillar Trim Panel. Refer to WSM, Section 501-05 Interior Trim and Ornamentation,
Removal and Installation, A-Pillar Trim Panel.
7. Disconnect the headliner wiring harness connector C900 found in the left A-Pillar. (Figure 1)
Figure 1

8. Disconnect the rear washer hose found in the left A-Pillar. (Figure 2) Refer to WSM, Section 501-16 Wipers and Washers, General Procedures, Washer Hose
Coupling.
Figure 2

9. Remove the sun visors on both sides. (Figure 3)
Figure 3

1. Position the sun visor screw cover aside.
2. Remove the sun visor screw.
3. Rotate the sun visor downward.
4. Disconnect the sun visor electrical connector.
10. Remove the sun visor clips on both sides (Figure 4). On both sides, remove the screw and the sun visor clip.
Figure 4

11. Remove the rear view mirror cover by releasing the clips holding the rear view mirror cover in place. (Figure 5)
Figure 5

12. Disconnect C9128 connector going to the IPMA camera from the headliner.
13. Remove the front assist handles on both sides. (Figure 6)
Figure 6

1. Position the front assist handle down.
2. Remove the front assist handle retainers.
3. Remove the front assist handle clips.
14. Tuck the replacement coaxial cable into the headliner behind the headliner harness and use 3M™ film tape to overlay the new coaxial cable next to the existing
coaxial cable. (Figure 7) Use 3M™ film tape (not zip ties) to overlay the cable in the headliner and A-pillar, as using zip ties with sharp cuts near the side curtain
airbag may impede the airbag’s performance once installed. (Figure 8)
Figure 7

Figure 8

NOTE: Be sure to avoid kinking or routing the cable in such a way that it bends greater than 90 degrees over 30 mm (1.2 in), as sharp bends could damage
the cable. Press the 3M™ film tape firmly to the headliner to make sure the tape adheres adequately to the headliner.
15. On the male side of the headliner wiring harness electrical connector (C900), remove the existing coaxial cable pin from the connector, and install the coaxial pin
from the newly installed coaxial cable. Refer to Wiring Diagram, Connector Views, C900. (Figure 9)
Figure 9

16. 16. Reattach headliner to the roof using the headliner magnets and install new C9128 connector to the IPMA camera and reconnect the headliner wiring harness
electrical connector. Refer to Figures 10-11. Cut off the existing coaxial cable connectors to ensure the original cable is not used again.
Figure 10

Figure 11

17. Install the newly overlaid harness in A-pillar back onto the A-pillar mounting bracket, above the fasteners that hold the bracket in place. (Figure 12)
Figure 12

NOTE: The headliner harness must be correctly installed back on to the bracket to avoid impeding the side curtain airbag.
18. Power the vehicle on and wait 30 seconds. Clear and retrieve DTCs. Is C1001:31 and/or U3000:89 present in the IPMA?
1. Yes - proceed to Step 19 to replace the coaxial cable assembly running from the IPMA by overlaying the new coaxial cables next to the existing coaxial
cables and cutting off the existing coaxial cable connectors.
2. No - proceed to Step 29.
19. Remove the left A-Pillar trim panel if not already removed from Step 6. Refer to WSM, Section 501-05 Interior Trim and Ornamentation, Removal and Installation, APillar Trim Panel.
20. On left side, disconnect headliner wiring harness electrical connector C900.
21. Remove the left B-Pillar trim panel. Refer to WSM, Section 501-05 Interior Trim and Ornamentation, Removal and Installation, B-Pillar Trim Panel.
22. Remove the left loadspace trim panel. Refer to WSM, Section 501-05 Interior Trim and Ornamentation, Removal and Installation, Loadspace Trim Panel.
23. Remove left side body harness scuff plates located under Front Scuff Plate Trim Panel Rear Scuff Plate Trim Panel. (Figures 13-14)
Figure 13

Figure 14

24. Remove the driver side floor console front trim panel, passenger side footwell trim panel, and passenger side floor console front trim panel. Refer to WSM, Section
501-12 Instrument Panel and Console, Removal and Installation.
25. Overlay the new coaxial cable assembly next to the existing 14335 harness. (Figures 15–18) If extra cable length is present when routing the new coaxial cable,
loop and stow the excess length. Secure using small zip ties as shown on figure 18.
Figure 15

Figure 17

Figure 18

NOTE: Make sure to avoid kinking or routing the cable in such a way that it bends greater than 90 degrees over 30 mm (1.2 in), as sharp bends could
damage the cable.
26. Overlay the new coaxial cable to the C2563 connector found in the passenger footwell. (Figures 19-21) Once the new C2563 connector is in place, cut off original
coaxial cable connectors. If extra cable length is present when routing the new coaxial cable, loop and stow the excess length. Secure using small zip ties.
Figure 19

Figure 20

Figure 21

NOTE: Make sure to avoid kinking or routing the cable in such a way that it bends greater than 90 degrees over 30 mm (1.2 in), as sharp bends could
damage the cable.
27. Is the vehicle equipped with minor feature codes HKLAF or J3QAA? To confirm a vehicle is built with a certain minor feature code, review the build information by
double-clicking the VIN in the upper left corner in PTS.

is in place, cut off the original coaxial cable connector. If extra cable length is present when routing the new coaxial cable, loop and stow the excess
length. Secure using small zip ties.
2. Make sure to avoid kinking or routing the cable in such a way that it bends greater than 90 degrees over 30 mm (1.2 in), as sharp bends could damage
the cable.
29. Power the vehicle on and wait 30 seconds. Clear and retrieve DTCs. Is C1001:31 and/or U3000:89 present in the IPMA?
