Is the APIM unit the same thing as the Image Processor? Bad cameras?
Is the Image Processor and APIM unit the same thing? Can you use those words interchangeably?
The rear and forward facing camera view in my truck sometimes have a blacked out or sometimes blued out area.
I've had the "image processor" replaced twice now but the issue keeps coming back. Today the dealership said they replaced the APIM unit (which they also called it the APIM the image processor earlier) but the issue still persists.
They are now suspecting a faulty camera and have that part ordered. I don't think it's the camera as it happens in both the front and rear camera.
Here is what's happening in reverse though similar systems with the front camera as well.
Thanks fully it's under warranty. All the issues with this truck are frustrating.

They are not the same things. The APIM is Accessory Protocol Interface Module. The IPMA is the Image Processing Module A and the IPMB is the Image Processing Module B.
The IPMA is located behind the windshield in the area where the interior rear view is mounted. It is used for Rain Sensing Wipers, Lane Keeping Assist, and Auto Hi Headlamp.
APIM
The APIM can be operated with the ignition in RUN, ACC, or OFF.
The APIM receives stereo and mono inputs. Stereo inputs include audio from the USB port, audio input jack, and connected Bluetooth media device. Mono inputs include audio from the outside device during a phone call and inputs from the SYNC® microphone.
The APIM sends stereo and mono audio signals to the ACM as fluctuating AC voltage. Stereo outputs include audio from the USB port, audio input jack, and connected Bluetooth media device. Mono outputs include audio from the TTS feature, incoming call ringtone, ringback tone, outside device during a phone call, voice or tone prompts initiated from the steering wheel switches and infotainment centerstack, route guidance voice or tone prompts, and SYNC® system instructions.
The TTS setting allows the customer to hear incoming caller information and incoming text messages through the audio system speakers so it does not have to be read from the centerstack infotainment display and/or device while driving.
The APIM consists of two internal modules: the CIP and the VIP. The modules are not replaceable individually, but can be programmed independently if required.
The CIP interfaces with all of the customer inputs to the APIM. It contains an analog-to-digital-to-analog converter, as well as the Bluetooth chipset. Any Application upgrades that are available to the customer are loaded directly to the CIP through the USB port.
The VIP provides an interface between the CIP and the vehicle inputs. Its main functions are controlling the APIM power management and translating inbound and outbound CAN signals.
The APIM requires programming when it is replaced.
IPMB (Vehicles Equipped With Rear Only Parking Aid Camera With PTBA or 360 Degree View Camera)
NOTE: The IPMB settings and configuration have no influence over the video signal from the parking aid cameras. The parking aid cameras provide a video signal any time they receive voltage and ground.
For vehicles equipped with a 360 degree view camera system, all camera views are produced by the IPMB, using input from one or more camera(s). The processed video signals are sent from the IPMB to the APIM on shielded, twisted pair circuits. The IPMB receives the video signals from the front, rear, LH and RH parking aid cameras through shielded, twisted pair circuits and determines which image(s) are sent to the APIM to be displayed on the FDIM. In addition to generating the camera views, the IPMB serves as a gateway between the front and rear
parking aid cameras and other modules on the HS-CAN2. It communicates with the front and rear cameras via the LIN and stores Diagnostic Trouble Codes (DTCs) for the cameras and the LIN in the event of a concern.
For vehicles equipped with a rear only parking aid camera system with PTBA, the IPMB serves as a gateway module between the video camera and other modules on the HS-CAN2. It communicates with the rear video camera via the LIN and stores Diagnostic Trouble Codes (DTCs) for the camera and the LIN in the event of a concern.
APIM serves as IPMA when there is no 360 camera system. If they already replaced both IPMB and APIM, then the problem is in the camera and/or the harness to it.
Bear, if you dont have the 360 cameras (which means you dont have an IPMB) then the APIM will. There's a bunch of diagrams that explain the CAN comms on who does what when the reverse line is triggered.
Texas fording- no, i have an xlt with just the back up camera. Its all factory, but when i bought it from the dealer, the salesman told me they replaced the screen, but no, it didnt have a camera in it and it was probably just an aftermarket handle- ( liar…)
The wiring is factory, from the camera, to the main harness, all the way to the front, so im trying to find out and narrow down what to look for/ or whats missing, before i tear into the center stack.
