DESCRIPTION AND OPERATION 4.160DISCOVERY SERIES II For the RH front door low range speaker the power amplifier supplies a positive output on a KG wire to connector interface C0459-3/C0744-3, then on a BK wire from the interface to the speaker. The negative output from the RH front door low range speaker returns on a BR wire to connector interface C0459-4/C0744-4, then on a KR wire to the power amplifier. LH front speakers The positive output from the head unit is connected by a BW wire to connector interface C0229-22/C0067-22, then by a Y wire from the interface to the power amplifier. From the power amplifier the positive output continues on a YB wire to connector interface C0459-1/ C0744-1 LHD or C0463-1/C0744-1 RHD, then on an RB wire from the interface to the LH front door mid range speaker. From the interface (C0459-1 LHD or C0463-1 RHD), a YB wire also supplies the positive output to the LH A post high range speaker. The negative output of the LH front door mid range speaker is connected by a KB wire to connector interface C0459-2/C0744-2 LHD or C0463-2/C0744-2 RHD, then by a YK wire to the power amplifier. A YK wire also connects the negative output from the LH A post high range speaker to the connector interface (C0459-2 LHD or C0463-2 RHD). From the power amplifier, the negative output is connected by an O wire to connector interface C0229-23/ C0067-23, then by a BN wire to the head unit. For the LH front door low range speaker the power amplifier supplies a positive output on an OB wire to connector interface C0463-3/C0744-3, then on a BK wire from the interface to the speaker. The negative output from the RH front door low range speaker returns on a BR wire to connector interface C0463-4/C0744-4, then on an OK wire to the power amplifier. LH rear speakers The positive output from the head unit is connected by a BY wire to connector interface C0229-24/C0067-24, then by a U wire from the interface to the power amplifier. From the power amplifier the positive output continues on a SK wire to connector interface C0435-1/ C0803-1, then on a BU wire from the interface to the LH rear door low range speaker. A second BU wire connects the positive output connection of the LH rear door low range speaker to the LH rear door high range speaker. The negative output of the LH rear door high range speaker is connected by a BG wire to the LH rear door low range speaker. A second BG wire connects the negative output connection of the LH rear door low range speaker to connector interface C0435-2/C0803-2. From the interface the negative output is connected by an SO wire to the power amplifier. From the power amplifier the negative output is connected by a P wire to connector interface C0229-25/C0067-25, then by a BO wire to the head unit.
DESCRIPTION AND OPERATION DISCOVERY SERIES II 4.161 Tail door speakers The power amplifier is connected to tail door low range speaker 1 on a KB wire. From tail door low range speaker 1 the connection returns on an RB wire to the power amplifier. The power amplifier is connected to tail door low range speaker 2 on an NB wire. From tail door low range speaker 2 the connection returns on a WB wire to the power amplifier.
DESCRIPTION AND OPERATION 4.162DISCOVERY SERIES II TRAILER SOCKET DESCRIPTION General The 7 pin trailer socket is mounted on the rear bumper to provide power feeds for the exterior lighting of a trailer or caravan. Refer to Description and Operation of individual exterior lighting circuits for trailer socket details.
DESCRIPTION AND OPERATION DISCOVERY SERIES II 4.163 PARK DISTANCE CONTROL (PDC) DESCRIPTION General Park Distance Control (PDC) provides an audible warning to the driver when any obstacles are in the path of the vehicle during reverse parking manoeuvres. The system consists of four ultrasonic sensors mounted in the rear bumper, an ECU a PDC switch, and a sounder. For detailed information on PDC, refer to the Driving Aids section of the Workshop manual. OPERATION PDC Operation Circuit supply A feed from the battery positive terminal is connected by a R wire to the engine compartment fusebox, where it passes through fusible link 1 and fusible links 8. Fusible link 1 is connected in series with fusible link 7. Fusible link 7 provides a battery feed to the auxiliary circuits relay contacts. Fusible link 8 is connected to the passenger compartment fusebox by an NW wire. From the passenger compartment fusebox, current flows to the ignition switch on an N wire. Ignition switch supply When the ignition switch is in position I, current flows from the ignition switch on an LGW wire to fuse 26 of the passenger compartment fusebox. Fuse 26 provides a feed to the auxiliary circuits relay coil on an LG wire. The relay coil is earthed on a B wire via earth header C0018. When the ignition switch is in position II, current flows from the ignition switch on a Y wire to fuse 25 of the passenger compartment fusebox. Fuse 25 provides a feed to the reverse lamp switch (manual vehicles only) or the automatic transmission starter inhibitor/reverse lamp switch (automatic vehicles only) on a GY wire. PDC ECU When energised, the auxiliary circuits relay provides a feed to fuse 16 of the passenger compartment fuse box on a WG wire. Current flows through fuse 16 to the PDC ECU on an LGO wire. The PDC ECU is earthed on a B wire vie earth header C0707.
DESCRIPTION AND OPERATION 4.164DISCOVERY SERIES II PDC Switch The PDC switch is used to switch off PDC if a trailer is attached. The PDC ECU provides a feed to the PDC switch on an RS wire. When the switch is pressed, the contacts close momentarily and a signal is returned to the PDC ECU on an S wire. When the PDC ECU registers this signal, it will deactivate PDC. Reverse Gear When reverse gear is selected, current from fuse 25 flows across the reverse lamp switch (manual vehicles only) or the automatic transmission starter inhibitor/reverse lamp switch (automatic vehicles only) to the PDC ECU on a GN wire. When the PDC ECU receives this feed it registers that reverse gear has been selected and activates PDC. PDC Sensors The PDC ECU provides a feed to connector interface C2403/C2404 on a WG wire, and from the connector interface to all four PDC sensors on W wires. The sensors are earthed on B wires to connector interface C2404/C2403, and from the connector interface to the PDC ECU on a BG wire. The PDC sensors provide distance signals to the PDC ECU as follows: zThe RH outer PDC sensor provides a signal to the ECU on an O wire. zThe RH inner PDC sensor provides a signal to the ECU on a Y wire. zThe LH inner PDC sensor provides a signal to the ECU on a U wire. zThe LH outer PDC sensor provides a signal to the ECU on a G wire. PDC Speaker The PDC ECU powers the PDC speaker to give the driver an audible indication of the distance to an obstacle. The PDC ECU provides the speaker a positive signal on a K wire and a negative signal on an N wire.
