Conditions
B1471: Generated in the event of incorrect data or no data from the Sensonic for more than 5 seconds.
B1473: Communication lead between the Saab Information Display (SID) and Sensonic shorted to ground.

Fault symptoms
Messages from the Sensonic not displayed on the SID.


Important: Diagnostic trouble code B1471 could be a consequential fault of B1473.


Diagnostic procedure
1 Connect a Intellegent Saab Tester (ISAT) Scan Tool.
Select "SAAB INFO DISPLAY".
Select "READ VALUES".
Select "DATA FROM ACS".

2 Simulate a message.
Engage a high gear, for example, and turn the ignition switch to the ON position. This should generate the "DISENGAGE GEAR" message on the SID and Intellegent Saab Tester (ISAT) Scan Tool.

If no message appears on either the SID or ISAT Scan Tool, see point 3.

If the message does appear, the fault is intermittent. See point 4.
3 Wiring harness check
Check the wiring between pin 6 of the SID unit and pin 24 of the Sensonic control module for continuity and/or shorting to ground.

If the wiring harness is intact, change the Sensonic control module.
4 Connector check
Check the connectors for slide-out and corrosion.
