Tests
3. Install test harness in series with wiring harness and
propel speed change solenoid valve (B).
4. Turn key switch to ON but do not start engine.
5. Turn propel speed switch to fast speed (rabbit).
Turn propel speed switch to slow speed propel (turtle).
Indicator light must be ON indicating there is continuity
in the wiring harness and there is a signal from engine
and pump controller.
6. Start engine.
7. Actuate propel function.
8. Turn propel speed switch to fast speed (rabbit).
The brightness of indicator light must increase slightly
while propelling in fast speed.
If light goes OUT or brightness does not increase,
check wiring harnesses, solenoid coil, propel pressure
switch, pump pressure, and pump control pressure
sensors. (See procedure in Group 9015-15.)
