Circuit/System Testing DTC B395A 08
- Ignition/Vehicle & All vehicle systems - Off
- Disconnect the electrical connector: X3 @ K157 Video Processing Control Module
- Wait for greater than 5 s.
- Connect appropriate EL-52552pinout tool to K157 Video Processing Control Module
- Ignition - On/Vehicle - In Service Mode
- Test for 7 to 11 V between the test points: Signal circuit terminal 2-RD @ 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
- If not between 7 and 11 V
- Ignition/Vehicle & All vehicle systems - Off
- Disconnect the electrical connector: B87 Rearview Camera
- Locate the appropriate pinout adapter and load test loop adapter from EL-52552 COAX FAKRA Cable Adaptor Kit.
- Connect the 2 adapters together, measure and record the resistance between the terminals at the pinout adapter.
- Disconnect the 2 adapters and connect each one to the appropriate end of the coax cable.
- 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
- Go to next step: If within 5 Ω of the reading from step 10.
- If not within 5 Ω of the reading from step 10.
- Replace the component: B87 Rearview Camera
- Apply the parking brake.
- Engine Running Transmission in Reverse
- 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
- If the DTC is set
- All OK.
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.
