Service Procedure
1. Is DTCs C1001:31 and/or U3000:89 stored in the IPMA?
(1). Yes - inspect the coaxial cables between the IPMA and the IPMA camera for loose connections. Perform a
wiggle test to check C900 and C9128 connectors for loose connections. If no loose connections are present,
proceed to Step 2. If loose connections are present, reconnect and proceed to Step 3.
(2). No - proceed to Step 27.
2. Power the vehicle on and wait 30 seconds. Clear and retrieve the DTCs. Is C1001:31 and/or U3000:89 present in
the IPMA?
(1). Yes - proceed to Step 4.
(2). No - the issue is intermittent. Replace both sections of coaxial cable running from the IPMA Camera to the
IPMA following Steps 4-15 and Steps 17-24, then proceeding to Step 25.
3. 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 4.
(2). No – proceed to Step 27.
4. Replace the coaxial cable running from the IPMA camera to the 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 Workshop Manual (WSM), Section 501-05 Interior Trim and Ornamentation, Removal
and Installation, A-Pillar Trim Panel.
5. Disconnect the left headliner wiring harness found in A-pillar. (Figure 1)
