If the engine speed exceeds 5000 r/min in 1st, 2nd, 3rd or 4th gear, the lamp will also light up, regardless of the engine load.
To avoid incorrect indications, the system will be switched out under the following conditions:
the radiator coolant temperature sensed by engine temperature transmitter 202 is below 47.6°C.
at engine idle - pin 1 of throttle angle transmitter 203 is earthed.
when fifth gear is engaged.
In addition, all input signals must have a duration of at least 0.75s.
Fault-tracing hints
1987 model
1. Set the ignition switch to the drive position and check fuse 7. Also check that the supply to the fuse is live.
2. Check lamp 47K.
3. Check that the switches in the system close and open the circuit under the specified conditions.
4. Check that relay 270 is receiving ignition pulses
5. Check the connectors and the earth connections
1988 model
The instructions for the 1987 model can be used when fault-tracing on cars with turbocharger.
When fault-tracing on cars without turbocharger, check that the supply to relay 270 is live and make sure the connectors and earth connections are in
good condition. Check also the control unit and related transmitters. The shift-up indication will be operative only if the LH system is operating
properly.
