Circuit / System Testing DTC B1595 11, 13, 86

1. Ignition / Vehicle & All vehicle systems - Off
2. Disconnect the electrical connector: X2 @ K124 Image Processing Module
3. Wait for greater than 5 s.
4. Connect appropriate EL-52552 pinout tool to K124 Image Processing Module
5. Ignition - On / Vehicle - In Service Mode
6. Test for 7 to 11 V between the test points: Signal circuit terminal 1 @ K124 Image Processing Module & Ground (component side)
   • If not between 7 and 11 V 

     Replace the component: K124 Image Processing Module

   • Go to next step: If between 7 and 11 V 
7. 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 and all inline connections, all of which can cause reception issues.

8. Disconnect the electrical connector: B174G Front View Driver Information Camera - Grille
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 faulty coax cable segment.

    • Go to next step: If within 5 Ω of the reading from step 10. 
13. Replace the component: B174G Front View Driver Information Camera - Grille
14. Apply the parking brake.
15. Engine Running Transmission in Reverse
16. Verify the DTC does not set.
    • If the DTC is set 

      Replace the component: K124 Image Processing Module

    • Go to next step: If the DTC is not set
