HOW TO USE THIS MANUAL

Harness Indication

Letter designations next to test meter probe indicate harness
(connector) wire color.

Connector numbers in a single circle M33 indicate harness con-
nectors.
Component Indication
Connector numbers in a double circle F211 indicate component connectors.
Switch Positions
Switches are shown in wiring diagrams as if the vehicle is in the “normal” condition.

Fitting AdjustmentEIS000LF
VERTICAL/LATERAL CLEARANCE ADJUSTMENT
1. With striker removed, loosen hinge mount nuts on the back door and close it.
2. Make lateral clearance and clearance to rear window glass equal. Open back door to tighten mounting
bolts to specified torque.
3. If taking the steps above does not result in fine adjustment,
remove headliner and loosen the hinge mount nuts on the vehi-
cle for further adjustment.
