Surround Vision Camera System Malfunction

Diagnostic Instructions Perform the Diagnostic System Check prior to using this diagnostic procedure: Diagnostic System Check - Vehicle Review the description of Strategy Based Diagnosis: Strategy Based Diagnosis An overview of each diagnostic category can be found here: Diagnostic Procedure Instructions Circuit/System Description For an overview of the component/system, refer to: Surround Vision Camera Description and Operation

Circuit	Description
Camera Video Signal	Coaxial Camera Signal

Diagnostic Aids The following conditions could cause component performance issues: Surround Vision Camera Ambient Light Intensity — High /Low Camera Blocked — Debris /Ice /Mud /Snow Temperature — High /Low An open in the shield of the video signal circuit can cause a distorted screen. If the Video Processing Module cannot calibrate all cameras, the rear vision image may be displayed without projected path lines. If the Video Processing Module loses communication with the Power Steering Control Module, the rear vision image may also be displayed without projected path lines. An open in the backup lamp control circuit, defective backup lamps, or incorrect/aftermarket backup lamps can cause erratic circuit behavior such as unwanted voltage on circuit when vehicle is no longer in REVERSE. The rear vision image display remaining active after the vehicle is shifted out of REVERSE can also be an indication of backup lamp control circuit issues.

1. Ignition » On / Vehicle » In Service Mode
2. Verify A22 Radio Control displays infotainment system information properly. ⇒ If the component does not work as specified Refer to: Symptoms - Entertainment. ⇓ If the component works as specified
3. Verify DTC B198E or B2545 is not set. ⇒ If the DTC is set Refer to: Diagnostic Trouble Code (DTC) List - Vehicle. ⇓ If the DTC is not set
4. Perform the following visual inspections: Misalignment of the components: B87 Rearview Driver Information Camera Visible Damage Dirty ⇒ If a condition exists » Repair or replace as necessary ⇓ If none of the conditions exists
5. Verify the surround vision camera system is calibrated. ⇒ If the surround vision camera image displays an hour glass. Refer to Video Processing Control Module Calibration ⇓ If the surround vision camera image does not display an hour glass.
6. Refer to: Circuit/System Testing Circuit/System Testing Circuit/System Testing One camera image malfunction
7. Ignition/Vehicle & All vehicle systems » Off
8. Disconnect the appropriate electrical connector: @ K157 Video Processing Module
9. Wait for greater than 5 s.
10. Connect appropriate EL-52552 pinout tool to K157 Video Processing Module
11. Ignition » On / Vehicle » In Service Mode
12. Test for 7 to 11 V between the test points: Signal circuit terminal @ K157 Video Processing Module & Ground (component side) ⇒ If not between 7 and 11 V Replace the component: K157 Video Processing Module ⇓ If between 7 and 11 V
13. Ignition/Vehicle & All vehicle systems » Off

Note

Before testing the coax cable, check the cable’s exterior for being pinched, cut, damaged, or having loose connections at the components, all of which can cause reception issues.

8. Disconnect the appropriate electrical connector: @ Surround Vision Camera
9. Locate the appropriate pinout adapter and load test loop adapter from EL-52552 COAX FAKRA Cable Adaptor Kit.
10. Connect the 2 adapters together, measure and record the resistance between the terminals at the pinout adapter.
11. Disconnect the 2 adapters and connect each one to the appropriate end of the coax cable.
12. At the pinout adapter test terminals, measure the total resistance of the coax cable loop including the connected load test adapter. ⇒ If not within 5 Ω of the reading from step 10. Replace the coax cable ⇓ If within 5 Ω of the reading from step 10.
13. Replace the component: Surround Vision Camera
14. Apply the parking brake.
15. Engine Running Transmission in Reverse
16. Verify the repair corrected the DTC/symptom. ⇒ If the repair did not correct the DTC/symptom Replace the component: K157 Video Processing Module ⇓ If the repair corrected the DTC/symptom
17. All OK. All camera images distortedAll Cameras
18. Ignition/Vehicle & All vehicle systems » Off
19. Disconnect the electrical connector: X1 @ K157 Video Processing Module
20. Test for less than 10 Ω between the test points: Ground circuit terminal 3 & Ground ⇒ If 10 Ω or greater 3.1. Disconnect the appropriate ground connection: 3.2. Test for less than 2 Ω between the test points: Ground circuit terminal 3 @ Component harness & The other end of the circuit ⇒ If 2 Ω or greater » Repair the open/high resistance in the circuit. ⇒ If less than 2 Ω » Repair the open/high resistance in the ground connection. ⇓ If less than 10 Ω
21. Ignition » On / Vehicle » In Service Mode
22. Verify a test lamp turns On between the test points: Each B+ circuit terminal & Ground ⇒ If the test lamp does not turn On and the circuit fuse is OK 5.1. Ignition/Vehicle » Off 5.2. Test for less than 2 Ω between the test points: Each B+ circuit terminal @ Component harness & Fuse ⇒ If 2 Ω or greater » Repair the open/high resistance in the circuit. ⇒ If less than 2 Ω » Refer to: Power Mode Mismatch ⇒ If the test lamp does not turn On and the circuit fuse is open 5.1. Ignition/Vehicle » Off 5.2. Test for infinite resistance between the test points: Each B+ circuit terminal @ Component harness & Ground ⇒ If less than infinite resistance » Repair the short to ground on the circuit. ⇓ If the test lamp turns On
