TOD 6 B. MOMENTARY SWITCH TOD activation switch is mounted on the fascia switch. Fascia switch is located in between audio system and HVAC system on the central console. This switch is used for: 1. Shifting from 4x2 to Auto and vice versa. In auto mode all four wheels are driven at 1:1 speed ratio. 2. 4x2 switch LED in FASCIA will be  ON, if vehicle is in 2WD (Two wheel drive) Mode  OFF, if vehicle is in Auto Mode. 3. If vehicle is in 4x2 mode and the non-latch cable switch is pressed, amber colored LED blinks until transfer case shifts into Auto Mode and then turns OFF. The LED will not blink when shifting from Auto to 4x2 mode. NOTE  When TOD is in “4 X 4 / Auto” mode and Ignition switch is turned to “ON” position, you will hear a slight noise from the Axle connect mechanism. Similarly you will hear same noise while changing over from 4 X 2 to 4 X 4 (Auto) mode and vice-versa.  While changing over from ‘4X2’ to ‘4X4/AUTO’ or vice-versa, the vehicle speed should be below 80kmph. For other details refer fascia switch section in electrical section. C. WARNING LAMP After Ignition ON, TOD Warning Lamp is ON till approximately 3 seconds. If there is a fault, the warning lamp remains ON continuously. Connect the diagnostics tool to diagnose the faults. D. GEROTOR PUMP The Gerotor pump is positive displacement pump which lubricates the inner part of transfer case. This pump is mounted on the output shaft. The output shaft is provided with drilled holes for circulation of oil. A strainer is provided at the suction end of the pump through which oil is sucked into the pump inlet. The strainer is locked to the case cover with the help of magnet. This magnet attracts the metallic chips and needs to be cleaned properly before assembly. The lubrication oil flows through holes of the output shaft which in turn lubricate the inner parts of partial transfer case.
