Diagnostic trouble code B1426 could be a consequential fault of B1428 if that DTC has also been generated.

Diagnostic procedure
1 If diagnostic trouble code B1428 has also been generated, continue fault diagnosis under that DTC.
2 If diagnostic trouble code B1428 has not been generated, select the Intellegent Saab Tester (ISAT) Scan Tool menu "SAAB INFO DISPLAY" and then "READ VALUES" and "DATA FROM ICE".
3 Simulate a message by removing a fuse or bulb, see "Checking the ICE Data". Read the result on the ISAT Scan Tool display.

If this works, clear the trouble code.

If the right result is not obtained, check the wiring for continuity as described in DTC B1428.
