Operation - Section 3 OM3006.3 04/98 Page 3-28 Instrument Panel and Indicators Tachometer Automatic Transmission Mechatronics Monitor The Tachometer (13, Figure 3-8) indicates 0-2500 RPM engine speed. Each bar represents 100 RPM. This red indicator (19, Figure 3-8) flashes whenever any abnormality occurs in the mechatronics related parts of the trans- mission control system.
Other Mechatronics Monitor (OPTIONAL) Lock-up Pilot Lamp This red indicator (20, Figure 3-8) flashes whenever any abnormality occurs in the mechatronics related parts of the PMC (Powertrain Management Control) sys- tem, RCM (Retard Control Monitor) sys- tem, PLM (PayLoad Meter) system, and the suspen- sion control system . The Lock-Up Pilot Lamp (14, Figure 3-8) lights up (blue) whenever the torque con- verter is locked up and the transmission enters direct drive. Fuel Level Monitor Shift Limiter Pilot Lamp The Shift Limiter Pilot Lamp (15, Figure 3-8) lights up (blue) whenever the shift limiter switch (on center console) is acti- vated.
This red indicator (21, Figure 3-8) flashes whenever the remaining fuel in the fuel tank goes below 40 gal. (150 liters). When this indicator flashes, check the fuel level gauge (22) and/or add fuel to the truck fuel tank. Shift Indicator Fuel Gauge The Shift Indicator (16, Figure 3-8) indicates the lever position of the transmission range selector. The Fuel Gauge (22, Figure 3-8) indicates the amount of fuel in the fuel tank. If there is more than 40 gal. (150 liters) of fuel in the tank while the engine is operating, the green range illuminates. If there is less than 40 gal. (150 liters) of fuel in the tank, the red range illuminates.
Transmission Shift Position Pilot Lamp Engine Power Derate Monitor This red indicator (23, Figure 3-8) flashes to alert the operator that the PMC (Power- train Management Controller) has de- tected an engine fault and is signalling the Centry Fuel Control system to reduce power output to protect the engine. The Transmission Shift Position Pilot Lamp (17, Figure 3-8) will indicate the specific gear range in which the transmission is actually operating ; R, N, 1, 2, 3, 4, 5, 6, or 7. Engine Controller Monitor F1 Start Monitor This red indicator (18, Figure 3-8) flashes whenever any abnormality occurs in any of the engine control systems.
This blue indicator (24, Figure 3-8) illumi- nates whenever the F1 Shift Limit switch (on center console) is activated.
