Back Door Damper Stay
NOTICE: Handling the damper. .
(a) Do not disassemble the damper because the cylinder
is filled with pressurized gas.
(b) If the damper is to be replaced, drill a 2.0 ± 3.0ttm
(0.079 ± 0.118 in.) hole in the bottom of the removed
damper cylinder to completely release the
high±pressure gas before disposing of it.
(c) When drilling, chips may fly out, so work carefully.
(d) The gas is colorless, odorless and non poisonous.
(e) When working, handle the damper carefully. Never
score or scratch the exposed part of the piston rod,
and never allow paint or oil to get on it.
(f) Do not turn the piston rod and cylinder with the damp-
er fully extended.
REMOVAL OF DAMPER STAY
1. REMOVE DAMPER STAY UPPER END FROM BACK
DOOR
2. REMOVE DAMPER STAY LOWER END FROM BODY
INSTALLATION OF DAMPER STAY
1. INSTALL DAMPER STAY UPPER END TO BACK DOOR
2. CONNECT DAMPER STAY LOWER END TO BODY
ADJUSTMENT OF BACK DOOR
1. ADJUST DOOR IN FORWARD/REARWARD AND
LEFT/RIGHT DIRECTIONS
Adjust the door by loosening the hinge bolts.
2. ADJUST DOOR LOCK STRIKER
(a) Loosen the mounting bolts.
(b) Using a plastic hammer, tap the striker to adjust it.

Low Oil Pressure Warning
INSPECTION OF PRESSURE WARNING
1. INSPECT WARNING LIGHT OPERATION
(a) Disconnect the connector from the pressure switch
and ground the connector on the wire harness side.
(b) Turn the ignition switch ON, check that t he warning
light lights.
If the warning light does not light, test the bulb.
2. INSPECT PRESSURE SWITCH OPERATION
(a) Disconnect the connector from the switch.
(b) Check that there is continuity between terminal and
ground with the engine stopped.
(c) Check that there is no continuity between terminal
and ground with the engine running.
HINT: Oil pressure should be over 0.3 kg/cm2 (4.3 psi, 29
kPa).
If operation is not as specified, replace the switch.If resistance value is not as specified, replace the send-
er gauge. 3. MEASURE SENDER GAUGE RESISTANCE
Measure the resistance between terminal and ground.

PRECAUTIONS
1. Care must be taken to replace each part properly as it
could affect the performance of the brake system and re-
sult in a driving hazard. Replace the parts with parts of the
same part number or equivalent.
2. It is very important to keep parts and the area clean when
repairing the brake system.
