Controls and Operating

Hydraulic Controls
The braking, steering, body control and transmission oil cooler are all
controlled by the main hydraulic valve, which is mounted on the chassis.
However, the body control and transmission oil cooler are electronically
monitored by the ECU which is mounted in the cab on the right of the
operator’s seat. The TCU warns the operator when a problem develops,
and helps to diagnose errors.
There are two LEDs on the MCU. The top LED illuminates green when
indicating power on, and the bottom LED flashes either red or yellow
depending on status. If there are no errors, the bottom LED flashes yellow
to indicate normal status. If either LED flashes red, this indicates an error
has occurred. The rate of flashing gives an immediate diagnosis as to the
nature of the error. Further information can be obtained from the MCU by
plugging in a diagnostic data reader to the RS232 diagnostic test point.
