1 Securing ring 2 Shaft oil seal 3 O-ring seal 4 Pump housing 5 Ring gear 6 Crescent spacer 7 Roller bearing 8 Impeller 9 Centering pin 10 Spring washer 11 Outlet port (high pressure) 12 Inlet port (low pressure) The pump comprises a housing, a crescent spacer, an impeller and a ring gear. The housing has inlet and outlet ports to direct
flow and is located in the intermediate plate by a centering pin. The pump action is achieved by the impeller, ring gear and
crescent spacer.

The crescent spacer is fixed in its position by a pin and is located between the ring gear and the impeller. The impeller is
driven by drive from the torque converter hub which is located on a needle roller bearing in the pump housing. The impeller
teeth mesh with those of the ring gear. When the impeller is rotated, the motion is transferred to the ring gear which rotates
in the same direction.

The rotational motion of the ring gear and the impeller collects fluid from the intake port in the spaces between the teeth.
When the teeth reach the crescent spacer, the oil is trapped in the spaces between the teeth and is carried with the rotation
of the gears. The spacer tapers near the outlet port. This reduces the space between the gear teeth causing a build up of fluid
pressure as the oil reaches the outlet port. When the teeth pass the end of the spacer the pressurized fluid is released into
the outlet port.

The fluid emerging from the outlet port is passed through the fluid pressure control valve. At high operating speeds the
pressure control valve maintains the output pressure to the gearbox at a predetermined maximum level. Excess fluid is
relieved from the pressure control valve and is directed, via the main pressure valve in the valve block, back to the pump inlet
port. This provides a pressurized feed to the pump inlet which prevents cavitation and reduces pump noise.

OPERATION System Operation

The fuel pump is a variable-speed rotary-vane type, which operates in a fuel pump module located in the RH side of the fuel tank. A venturi transfer pump is located in the RH side of the tank. The fuel pump module is secured in the fuel tank with a bayonet style locking ring that is welded into the tank structure. The fuel pump module has an integral top plate for the
external pipe work and electrical connectors.

Fuel level is biased towards the RH compartment in the fuel tank by drawing fuel through the internal cross over pipe via the jet pump, which serves to deliver a constant supply of fuel to the transfer pump and swirl pot assembly. High pressure fuel
from the fuel pump is directed through the jet pump's orifice, creating a low pressure area to be formed in the cross over pipe.
The fuel is drawn into this low pressure area in the cross over pipe and directed into the swirl pot delivery pipes.
Fuel is pumped from the fuel pump to the fuel rail via the integral filter and pressure relief valve.

The pressure relief valve assists engine starting by retaining a pre-set fuel pressure in the supply pipe and fuel rail. The
pressure relief valve also limits fuel rail pressure due to temporary vapor increase in hot conditions and pressure caused by
sudden load changes, for example, a fully open to closed throttle transition.

To meet ORVR (on-board refueling vapor recovery) requirements, the fuel tank and associated components are designed to
minimize fuel vapor loss during refueling. This is achieved by preventing fuel vapor from the fuel tank venting directly to the
atmosphere. Instead fuel vapor is directed into the EVAP (evaporative emission) charcoal canister where it is stored before
being purged at intervals to the engine’s intake manifold.

North American Specification (NAS) vehicles feature additional connections and pipes at the rear of the filler head and also
incorporates a Diagnostic Monitoring Tank Leakage (DMTL) pump for leak detection requirements.

Check For Air Flow Specific DTCs Diagnostic Guidance Notes
B120F-98
Once the diagnostic process detailed above has been carried out and it has been identified that B122E-98 there has not been a failure of any of the climate units, then refer back to the relevant climate B122F-98 system DTC codes that have been recorded B1230-98 DTC codes listed that end in 7A or 98 indicate a possible air leak or air flow restriction within the B1231-7A system B1232-7A In these circumstances, starting with the seat base check all ducting connections for correct engagement and inspect ducting for signs of damage which could result in an air leak (for connection issues re-connect and test system). Only in the event of finding damage to the ducting of one of the units should the unit be replaced. Note that only the specific unit should be replaced Due to the design function of the system, both climate units in any one seat operate integrally. Therefore, if an issue is detected in one of the units then both units are shut down to protect the system until next ignition cycle. Under these circumstances, only replace the damaged unit and DO NOT replace both units DTC Index

NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).
