Operation - Section 3 OM3006.3 04/98 Page 3-30 Instrument Panel and Indicators Engine Coolant Level Parking Brake The Engine Coolant Level Monitor light (3, Figure 3-9) will illuminate, if the engine coolant level is below the sensor for a continuous period of 5 seconds. At the same time, a fault code will be registered in the Centry System. (Refer to CENTRY FUEL SYSTEM DIAGNOSTICS later in this section.) If this monitor lamp flashes and alarm buzzer sounds, stop truck, shutdown engine, and add coolant as re- quired.
The Parking Brake Monitor light (8, Figure 3-9) will illuminate if the transmission con- troller detects that the parking brake is applied or that the wire between the switch and the controller is cut or broken. Body Float The Body Float Monitor light (9, Figure 3-9) will illuminate if the transmission con- troller detects that the body is not seated on the frame rail or that the wire from the proximity switch and the controller is cut. When the dump body control lever is set to any position other than FLOAT, the Body Float Monitor lights up. When traveling, always set the lever to FLOAT position.
Low Steering Pressure The Low Steering Pressure Monitor light (4, Figure 3-9) will illuminate if the steering system pressure is below 1850 psi (12.8 MPa). The light may also indicate that the wire from the switch to the transmission controller is cut or broken. Transmission Oil Temperature The Transmission Oil Temperature Moni- tor light (10, Figure 3-9) will illuminate if the transmission controller detects that the oil temperature is over 248°F (120°C) Accumulator Pre-Charge The Accumulator Pre-Charge Monitor light (5, Figure 3-9) will illuminate, if the accumulator nitrogen pressure is below 850 psi (5 861 kPa).
The light may also indicate that the wire from the switch to the transmission controller is cut or broken. Service Brakes Applied The Service Brakes Applied Monitor light (11, Figure 3-9) will illuminate (amber), if the transmission controller detects that the rear brakes have been applied, or that the wire between the switch and the con- troller is grounded. Battery Charge Amps The Battery Charge Amps Monitor light (6, Figure 3-9) will illuminate, if the trans- mission controller detects low battery current at the ‘‘R’’ terminal of the alterna- tor while the engine is running or if the wire is cut. If the monitor lamp flashes, check the charging circuit.
Maintenance Monitor The Maintenance Monitor lamp (12, Fig- ure 3-9) will illuminate if the PMC (Power- train Management Controller), detects any of the following faults: Check Engine The Check Engine Monitor light (7, Figure 3-9) will illuminate if a problem occurs in the Centry engine control system. The light is also used to display the trouble code.
