6. Engine Coolant Temperature Gauge -
Indicates coolant temperature. If both tenth
& ninth flash out of phase while operating
the lift truck, overheating is indicated. Park the lift

8. G420F(E)/G424F(E)/G424I(E)/G430FE
Engine
(MIL)
G420F(E) and G424F(E) and G424I(E) and
G430FE engine control systems are equipped with
built-in fault diagnostics. Deteted system faults can
be displayed by the Malfunction Indicator Lamp
(MIL) as Diagnostic Fault Codes (DFC) or flash
codes, and viewed in detail with the use of service
tool software. When the ignition key is turned ON
the MIL will perform a self-test, illuminate once and
then go OFF. If a detected falut condition exists, the
fault or faults will be stored in the memory of the
engine control module (ECM). Once a fault occurs
the MIL will illuminate and remain ON. This signals
