DESCRIPTION AND OPERATION 4.60FREELANDER 02MY Reverse When reverse gear is selected, a main relay feed is able to flow from the transmission selector/inhibit switch (C0244) to the reverse lamp relay (C0935) on an NG wire. The reverse lamp relay (C0935) is earthed on a B wire and controls operation of the reverse lamps. For more information on reverse lamp operation, refer to the Brake and Reverse Lamps section of this manual. + BRAKE AND REVERSE LAMPS. A main relay feed is also supplied to the...

DESCRIPTION AND OPERATION FREELANDER 02MY 4.61 4th Gear To select fourth gear, only shift solenoid C is operated. The ATCU (C0932) will provide a feed to shift solenoid C (C0243) on an OU wire. 5th Gear To select fifth gear, shift solenoid A and shift solenoid C are operated. The ATCU (C0932) will provide a feed to shift solenoid A (C0243) on an R wire. Shift solenoid C (C0243) receives a feed from the ATCU (C0932) on an OU wire. 4 When 4 is selected, a main relay feed is able to flow from the...

DESCRIPTION AND OPERATION 4.62FREELANDER 02MY Manual (Steptronic) Mode When in sport mode, if the selector lever is moved to the + or - positions, the gearbox will automatically enter manual (Steptronic) mode. When the selector lever is moved to the - position, it provides a feed to the ATCU (C0932) on a GK wire. When the selector lever is moved to the + position, it provides a feed to the ATCU (C0932) on a GB wire. Manual gear changes can now be performed sequentially using the selector lever....

DESCRIPTION AND OPERATION FREELANDER 02MY 4.63 Torque Converter Lock-Up When the gearbox is in 4th or 5th gear, and the ATCU registers a high vehicle speed combined with a small throttle angle, the ATCU will lock the torque converter. This will enable maximum power to be transmitted to the road wheels. When this occurs, the ATCU (C0932) provides a PWM signal to the Lock-Up solenoid (C0243) on a U wire. The solenoid (C0243) is earthed via the ATCU (C0932) on an SB wire. For more details on torque...

DESCRIPTION AND OPERATION 4.64FREELANDER 02MY ELECTRONIC AUTOMATIC TRANSMISSION (EAT) – 02MY DESCRIPTION General The Jatco 5–speed automatic transmission fitted to Freelander is controlled by an Automatic Transmission Control Unit (ATCU). The ATCU is located inside the engine E-box, and receives information from the following sources to calculate when to operate the solenoid valves contained within the gearbox to enable quick, smooth, quiet gear changes; The Engine Control Module (ECM) via the...

DESCRIPTION AND OPERATION FREELANDER 02MY 4.65 OPERATION General Feed from the positive battery terminal (C0192) is supplied to the main relay and fusible link 3 (C0632) on an R wire. Both are located in the engine compartment fuse box. The battery also provides a feed to fusible link 4 of the engine compartment fuse box (C0632) on vehicles fitted with an instrument dimmer switch. For more information, refer to the Interior Lamps section of this manual. + INTERIOR LAMPS. Operation of the main...

DESCRIPTION AND OPERATION 4.66FREELANDER 02MY ATCU The ATCU monitors the operation of the automatic gearbox via four sensors: The temperature of the automatic transmission fluid (ATF) is measured by the fluid temperature sensor. The fluid temperature sensor (C0243) receives a feed from the ATCU (C0932) on a WK wire. The temperature sensor return (C0243) to the ATCU (C0932) is via a KB wire. As the temperature of the ATF rises, so the resistance of the sensor decreases. The ATCU registers this drop...
