NOTE: Slightly lift up oddments tray, disconnect air hose and remove oddments tray.
20 Route cable harness to multiple connector (arrow),instrument cluster and to connection point of temperature sensor (areas of engine hood cable).
NOTE: Retrofit multiple connector if not already installed.
21 Installation of multiple connector
- Screw multiple connector to heater box.
- Connect cables
1 rt/sw = Terminal 30,fusebox,electrics compartment F26
2 sw/rt = Terminal 15,fusebox,electrics compartment F27
3 br = Terminal 31,ground connection,transmission tunnel
4 gr/gn = Terminal 58,cable connector,transmission tunnel
5 rt/sw/ws = Terminal 15R,fusebox,electrics compartment F15
Cable connection
1 = to temperature indicator (In instrument cluster)
2 = to plug connection (Hall sensor)
22 Connect cable to cable connector,terminal 58d(x6/3)
23 In diesel-driven vehicles,route cable harness (refer to page 9) for Hall sensor (speed signal), from instrument cluster to multiple connector and cable connection of windshield frame (left defroster nozzle)
NOTE: Cable harness and Hall sensor are provided in gasoline engines.
24 Screw on Hall sensor (1).Clamp ground cable (2) to Hall sensor and to ground of instrument cluster under housing screw. (only for diesel-driven vehicles)
NOTE: As of vehicle ident.no.085 026 an electronic speedometer is installed and as a result of this the installation of the Hall sensor and associated cable harness is omitted.
25 Install temperature indicator (3).
26 Remove left signal strip (arrow) from instrument cluster, shorten by approx. 70mm and install again.
27 Remove radiator cowl.
28 Detach left headlamp panel and lift out.
29 Unscrew left cap for bumper.
30 Bolt temperature sensor with left cap to bumper.
31 Route cable under the radiator into the engine compartment through the rubber sleeve into the vehicle compartment.
NOTE: Clip cable to existing cable harness up to the fire wall.
32 Connect plug connections corresponding to schematic wiring diagram.
33 Install instrument cluster, switch panel, gear shift lover cover, steering wheel and all removed parts in reverse order.
34 Carry out functional test.
