OM3023 10/00 Operation - Section 3 Operating Instructions Page 3-35 15. Lock-up Pilot Lamp The Lock-Up Pilot Lamp (15, Fig- ure 3-7) lights up whenever the torque converter is locked up and the transmission enters direct drive. 20. Other Mechatronics Monitor (OPTIONAL) This red indicator (20) flashes when- ever any abnormality occurs in the mechatronics related parts of the PMC (Powertrain Management Control) sys- tem, PLM (Payload Meter) system, and the optional suspension control system. 21. Fuel Level Monitor This indicator (21) flashes when the remaining fuel in the fuel tank goes below 170 liters (45 gal). If it flashes, check the fuel level and add fuel. 16.
Transmission Shift Position Pilot Lamp The Transmission Shift Position Pilot Lamp (16) will indicate the specific gear range in which the transmission is actu- ally operating; R, N, 1, 2, 3, 4, 5, 6, or 7. 22. Fuel Gauge The Fuel Gauge (22) indicates the amount of fuel in the fuel tank. If there is more than 170 liters (45 gal) of fuel in the tank while the engine is operating, the green range lights. If there is less than 170 liters (45 gal) of fuel in the tank, the red range lights. 17. Shift Indicator The Shift Indicator (17) indicates the lever position of the transmission range selector. 23, 24, and 25.
(OPTIONAL) Suspension Mode Display Lamps This monitor displays the type of suspension mode being used. This OPTIONAL suspension feature automatically switches the damping characteristics of the suspension according to whether the truck is carrying a load, or whether the brake, steering, or dump controls are being operated. 18. Engine Controller Monitor This red indicator (18) flashes when- ever any abnormality occurs in any of the engine control systems. NOT USED with SAA12V140ZE-2 engine. 19. Automatic Transmission Mechatronics Moni- tor Normally, the SOFT mode (25) is used when travel- ing empty, and MEDIUM (24) is used when traveling loaded.
When using the service brakes or turning sharply, or when operating the dump control, the sus- pension mode is switched to HARD (23) to maintain the stability of the machine: front and rear, and left and right. This indicator is present in all instrument panels, but is inactive in trucks without this option. This red indicator (19) flashes when- ever any abnormality occurs in the mechatronics related parts of the trans- mission control system.
