Checking for a short-circuit

Measure the resistance between the fuse holder secondary side (left) and ground.

The ohmmeter should read infinite resistance.

If the value is correct, replace the fuse.

If the value is incorrect, fault-trace all affected relay circuits and component wiring for a short-circuit to ground.

HINT: Replace fuse. 

HINT: If the fuse blows immediately the short-circuit is in the relay power cable. 

HINT: If the fuse blows when the tailgate is opened the short-circuit is in the power supply cable for the component 

HINT: Relay supply cable: fuse 11D/6 terminal #5 relay base 2/67. 

HINT: Component supply cable: terminal #4 relay base 2/67 terminal #2 lock unit.
