Notes on Trouble-shooting:

Nominal Value:

Cause of fault:

(If nominal value is not attained)

 

If electric co-driver's seat adjustment is also not okay:

 

 

 

 

·   Check fuse F5

 

OK

·   Fuse F5 defective

 

If co-driver's seat adjustment is also not okay and fuse F5 is okay:

 

 

 

 

·   Ignition OFF

·   Remove fuse F5

·   Using multimeter, measure voltage at fuse socket F5

 

higher than 11.5 V

·   Lead interruption between fuse F5 and Ter. 30, battery voltage

 

·   Disconnect battery negative terminal

·   Release wiring harness connection X1 and disconnect

·   Insert fuse F5 again

·   Connect battery negative terminal

·   Using multimeter, measure voltage at X1/ Ter. 50

 

higher than 11.5 V

 

·   Lead interruption between F5 and X1/ Ter. 50

·   Lead interruption between X1/ Ter. 50 and derivation for driver's seat/ co-driver's seat

 

 

If new fuse F5 blows again:

 

 

 

 

·   Disconnect battery negative terminal

·   Disconnect F5

·   Release wiring harness connection X1 and disconnect

·   Connect battery negative terminal

·   Using multimeter, measure resistance at X1/ Ter. 50 to ground

 

higher than 200 kW

·   Short circuit to ground in lead between
X1/ Ter. 50 and fuse F5

 

·   Release 2-pin wiring harness connection for voltage supply of electrically adjustable co-driver's seat and disconnect from body wiring harness.

·   Using multimeter, measure resistance in 2-pin wiring harness coupling between Ter. 1 and ground

 

higher than 200 kW

·   Short circuit in body wiring harness between X1/ Ter. 50 and 2-pin wiring harness connection for voltage supply of electrically adjustable co-driver's seat

·   Short circuit in body wiring harness between X1/ Ter. 50 and control unit K103 in driver's seat

·   Control unit K103 defective

 

 

If nominal value is attained

 

 

·   Short circuit in co-driver's seat

 

If electric co-driver's seat adjustment is okay:

 

 

 

 

·   Ignition OFF, disconnect battery negative terminal

·   Remove driver's seat

·   Release 8-pin plug and remove from control unit K103

·   Using multimeter, measure voltage at 8-pin plug Ter. 1

 

higher than 11.5 V

·   Interruption in body wiring harness between X1/ Ter. 50 and 8-pin control unit plug Ter. 1

 

If nominal value is attained

 

·   Control unit K103 defective
