- Disconnect the E.C.U.
- Remove the cold-start injector, and place it above a graduated container.
- Disconnect the thermal switch, and connect terminal (( 46 )) to earth
- Switch the ignition on and actuate the starter motor. the quantity delivered must be approximately
135 cm3 /min ( 8 l/4 cuin’min 1.
- Disconnect the injector: its resistance must be 4.2 Q at 20” C
- Connect the injector to the thermal switch.
- If the water temperature is below 35” C, on operating the starter motor, the cold-start injector must supply
petrol for the followinq amounts of time
- 7.5 sets for a temperature of (( - 20” C ))

-1 ” ” (( 20” c >)
- On operating the starter. terminal (( 4 )) of the E.C.U. terminal board must be enerqized ( voltmeter between
terminals (( 4 )) and 0 5 )) 1.
10. Switch on throttle butterfly spindle ( Idling speed function ) : ( DIAGRAM 10 )
- Disconnect the E.C.U
- Using an ohmmeter, check that there is no resistance between terminals N 2 H and (( 18 H of the multiple
connector, without touching the accelerator pedal.

- Disconnect the E.C.U.
- Using a battery operated ohmmeter, check there is no resistance between terminals (( 3 H and (( 18 )) of the
multiple connector board, with the accelerator pedal fully depressed

2 - Visually check the condition of the terminals ( male connectors on the E-C U., and female connectors
on the multiple connector socket ).
- With the engine running, tap lightly on the E.C.U., to detect any possible defect in the soldering ( dry
joints ).

b ) Using an air breather chamber GX 03 294 01 A as
in photograph 14 758.
- Half fill the breather chamber with LHM fluid.
and keep (I finger on orifice (S a tn.
- Place the gouge supporting bracket ( 1) so
that surface F is approx. horizontal.
- Fill the gauge through orifice <( b n until the
level of the fluid reaches the min. mark on the
gauge.
4. Connect tube (3) from the gouge to the filler
orifice I. B. ADJUSTING THE GAUGE
Two methods ore possible
- Adjusting the gouge using an engine sump simulator.
-Adjusting the gauge on the vehicle.
1. Prepare (I jar as per diagram on page 2.
NOTE This simulator is also suitable for adjusting
a gouge on o GS (S Birotor ,n.vehicle.
2. Connect the rubber tube (2 i ( unmarked 1 to the tube
labelled (< mini CX n in the jar, and place the gouge
supporting bracket in the position it occupies on
the vehicle.
