B1103

Relay, radiator fan, high speed, open circuit

Fault symptom
The radiator fan does not go to the 2nd step.

Action
1 Check fuse 3 in the electrical distribution box.
2 Remove the relay and check the voltage supply to pin 4 (relay 86). There should be battery positive voltage. if this is not the case, check the cable assembly for breaks.
3 Connect the Intelligent Saab Tester (ISAT) and activate the radiator fan on high speed. Measure the voltage between 86 and 85, pins 4 and 5 respectively, with the relay removed. Use the ISAT and read the voltage with the help of a multi meter. The voltage should be
ON = BATT+
OFF = 0 V

If the measured value is correct, change the relay.

If not, check the cable assembly between connector H10-15 and the control module for open circuit.
4 If the fault remains, proceed to "Action Before Changing A Control Module".
