Circuit/System TestingDTC B395A 08

1. Ignition/Vehicle & All vehicle systems - Off
2. Disconnect the electrical connector:X4 @ K157 Video Processing Control Module
3. Wait for greater than 5 s.
4. Connect appropriate EL-52552pinout tool to K157 Video Processing Control Module
5. Ignition - On / Vehicle - In Service Mode
6. Test for 7 to 11 V between the test points:Signal circuit terminal 1-YE @ K157 Video Processing Control Module & Ground (component side)
   • If not between 7 and 11 V 

     Replace the component:K157 Video Processing Control Module

   • Go to next step: If between 7 and 11 V 
7. Ignition/Vehicle & All vehicle systems - Off
8. Disconnect the electrical connector:B87 Rearview Camera
9. Connect appropriate EL-52552pinout tool to Coax Cable
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.

10. Test for less than 5 ohms between the test points:Coax Cable Center & The other end of the circuit
    • If 5 ohms or greater 

      Replace the component:Coax Cable

    • Go to next step: If less than 5 ohms 
11. Test for less than 5 ohms between the test points:Coax Cable Outer Shield & The other end of the circuit
    • If 5 ohms or greater 

      Replace the component:Coax Cable

    • Go to next step: If less than 5 ohms 
12. Test for infinite resistance between the test points:Coax Cable Outer Shield & Coax Cable Center
    • If less than infinite resistance 

      Replace the component:Coax Cable

    • Go to next step: If infinite resistance 
13. Replace the component:B87 Rearview Camera
14. Apply the parking brake.
15. Engine RunningTransmission in Reverse
16. Verify DTC B395A is not set.
    • If the DTC is set 

      Replace the component:K157 Video Processing Control Module

    • Go to next step: If the DTC is not set 
17. All OK.
