| All dimmable non-networked illumination is always on (networked illumination functions correctly) | Refer to the Pinpoint Test | GO to Pinpoint Test B |
| All dimmable illumination (networked and non-networked sources) does not dim or increase brightness | Refer to the Pinpoint Test | GO to Pinpoint Test C |
| The steering wheel switch(es) illumination is inoperative | Refer to the Pinpoint Test | GO to Pinpoint Test D |
| One Or More Dimmable Non-Networked Illumination Source Is Inoperative | Refer to the Pinpoint Test | GO to Pinpoint Test E |
| The RH front, RH rear or LH rear window control switch illumination is inoperative or always on (One-Touch Up and Down Front Windows) | Refer to the Pinpoint Test | GO to Pinpoint Test F |
| The LH front window control switch illumination is inoperative or always on (One-Touch Up and Down Front Windows) | Window control switch | VERIFY the operation of the power windows. If the power windows operate correctly, INSTALL a new LH front window control switch. If the power windows do not operate correctly, REFER to: Glass, Frames and Mechanisms - Vehicles With: One-Touch Open and Close Front Windows |
| The window control switch illumination is inoperative or always on (One-Touch Down Driver Window) | Wiring, terminals or connectors Window control switch |

| The FCIM illumination is inoperative/does not dim (with 4.2-inch [107mm] display) | Refer to the Pinpoint Test | GO to Pinpoint Test G |
| The FCIM illumination is inoperative/does not dim (with 6.5-inch [165mm] touchscreen display) | Network communication concern FCIM |
VERIFY the operation of the audio system. If the audio system operates correctly, INSTALL a new FCIM. If the audio system does not operate correctly, REFER to: Information and Entertainment System |
| The ACM illumination is inoperative/does not dim (without 6.5-inch [165mm] touchscreen display and without 4.2-inch [107mm] display) | Refer to the Pinpoint Test | GO to Pinpoint Test E |
| The FCDIM illumination is inoperative/does not dim | Network communication concern FCDIM |
VERIFY the operation of the audio system. If the audio system operates correctly, INSTALL a new FCDIM. If the audio system does not operate correctly, REFER to: Information and Entertainment System (w/ AM/FM/CD) REFER to: Information and Entertainment System (w/ AM/FM/CD/SYNC |
| The FDIM illumination is inoperative/does not dim | APIM FDIM |
VERIFY that the audio system can be operated from the FDIM. If the audio system responds normally to FDIM inputs, PERFORM the APIM Hardware Test. Refer to APIM HARDWARE TESTING If the FDIM illumination still does not function correctly after the repair, INSTALL a new FDIM. If the audio system does not respond normally to FDIM inputs, REFER to: Information and Entertainment System |
| The IPC illumination is inoperative/does not dim | Network communication concern IPC |
Using a diagnostic scan tool, PERFORM a network test. If the IPC passes the network test, Refer to IPC Hardware Testing . If the diagnostic scan tool responds with no communication with the IPC, REFER to: Communications Network |
| The HVAC module illumination is inoperative/does not dim (with DATC) | Network communication concern HVAC module |
Using a diagnostic scan tool, PERFORM a network test. If the HVAC module passes the network test, INSTALL a new HVAC module. REFER to: Climate Control Assembly If the diagnostic scan tool responds with no communication with the HVAC module, REFER to: Communications Network |
| The HVAC module illumination is inoperative/does not dim (with EATC) | Refer to the Pinpoint Test | GO to Pinpoint Test E |
