Display: < 5 .Q Note The wire is routed via two plug connections, 8. Removethe air-conditioningcompressor relay. 9. Connectohmmeter to terminal 85 and DME connector pin 62. Display: < 5 .Q Note The wire is routed via one plug connection. Test point 12 Motor of fresh-air blower Diagnosisconditions No control module fault stored. Voltage too low Supplyvoltage OK. Voltage too high Nominalblower voltage> 3 volts. Fault code 31 Nominalblower voltage stabilised. Voltage too low Note Voltage too low means that the measured blower voltage lies below the nominalblower voltage. 1. Check the heating activation relay. Battery positive voltage must be present at terminal 87 when the ignition is switchedon. 2.
