Cause of fault:
(If nominal value is not
attained)
|
|
If outside mirror adjustment is not possible
· Eliminate fault in driver's outside
mirror circuit according to section 5.5. Then proceed with the following
trouble-shooting if necessary
|
|
|
|
|
· Ignition OFF
· Separate wiring harness connection X12,
body/ co-driver's door (bayonet catch)
· Ignition ON
· Using multimeter, measure voltage in
wiring harness coupling X12 between Ter. 12 and Ter. 14
|
approx. 5 V
|
· Interruption or short circuit to ground
in body wiring harness between X12 and control unit K103
· Short circuit to battery voltage in
body wiring harness between X12 and control unit K103
|
|
|
· Ignition OFF and connect wiring harness
connection X12 again
· Remove co-driver's outside mirror
· Release 9-pin wiring harness connection
for outside mirror and separate from co-driver's door wiring harness
· Ignition ON
· Using multimeter, measure voltage in
9-pin wiring harness coupling (co-driver's door wiring harness) between
Ter. 4 and Ter. 5
|
approx. 5 V
|
· Interruption or short circuit to ground
in co-driver's door wiring harness
· Short circuit to battery voltage in
co-driver's door wiring harness
|
|
|
· Using multimeter, measure resistance in
9-pin wiring harness plug for co-driver's outside mirror

(horizontal potentiometer slider contact)
|
|
|
· Install co-driver's outside mirror
again
· Ignition OFF, disconnect battery
negative terminal
· Remove driver's seat
· Release 26-pin wiring harness plug from
