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
