OL
NOTE: Remember that each diode should drop
approximately 0.6 Vdc when positively biassed,
and read as an OL (open circuit) when negatively
biassed (leads reversed).
If, when measuring between pins 14 and 15 an
OL is obtained with both positive and negative
diode biassing, test the wiring harness continu-
ity between the gauge and switch assembly. If
harness continuity is good, replace the switch
assembly.
If any reading is significantly different than listed,
carry out the same test at the switch connector,
refer to the wiring diagram. If you obtain the same
results, replace the switch assembly.
If voltages measured on every switch are as
listed in the previous tables (or very close to it),
the switches and the wiring harness are good.
The fault may be within the gauge, or in the circuit
or component the function applies to.
HYDRAULIC PUMP
Hydraulic Pump Recommended Fluid
Always use automatic transmission fluid (ATF)
Dexron III.
NOTICE
To avoid serious damage to hy-
draulic pump and actuator, use only ATF
Dexron III. Do not use fluids other than the
recommended one, nor mix different types of
fluids for topping up.
Hydraulic Pump Fluid Level
Verification
NOTE: The fluid level will drop slightly during
break-in period because the actuator uses a small
amount of fluid to lubricate its moving parts. If a
large amount of fluid is required, check compo-
nents for leaks.
Reservoir in Vehicle
Place the vehicle level (longitudinally and transver-
sally). Make sure suspension is in DOCK MODE
position.
The fluid should be near reservoir plug.

1. Fluid level
Reservoir Out of Vehicle
Place the
reservoir vertically.
Using a ruler, measure the fluid level. The
reservoir is full when fluid level reaches
130 mm ± 5 mm (5-1/8 in ± 13/64 in).

To Add
Fluid
Remove the plug on the end of reservoir.
Using a syringe, fill up the reservoir to the recom-
mended level.
