Explorer AWD V6-4.0L VIN K Flex Fuel (2003)
Test F4-F7
Normal Operation
The parking aid module communicates with the diagnostic tool through the ISO 9141 communications network circuit 70 (LB/WH). If circuit 70
(LB/WH) becomes open or shorted to ground communications to that module will not be possible. Check circuit 70 (LB/WH) between the parking aid
module C4014 and the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in
circuit 70 (LB/WH), damage to the DLC C251, damage to the parking aid module C4014, or a problem in the in-line connector C2095 or C408.
