Power Distribution
Feed from the positive battery terminal (C0192) is provided to the seat relay and fuse 53.
Both are located in the passenger compartment fuse box (C0632). Fuse 53 (C0583) provides a constant battery feed to the ignition switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) on an R wire.
When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) to the seat relay coil (C0585) on a G wire.
Current flows through the seat relay coil (C0583) to earth on an N wire. This energizes the seat relay. The energized seat relay provides a feed to fuse 20 and fuse 21, which are also located in the passenger compartment fuse box.
Non-Memory Drivers Seat
Fuse 20 (C0584) provides a feed to the LH seat switch pack (C0773) on an RN wire. Fuse 21 (C0584) provides a feed to the RH seat switch pack (C0774) on an RN wire. Both the LH (C0773) and the RH (C0774) seat switch packs are earthed on N wires.
Memory Drivers Seat
Fuse 20 (C0584) provides a feed to the seat memory ECU (C0722) on an RN wire, and the upper backrest motor (C2308) on an RN then R wire. The seat memory ECU (C0722) is earthed on an N and an NB wire. The upper backrest motor (C2308) is earthed on an N wire.
Note. The upper backrest motor is only fitted on the 'Comfort' seat.
