Messages from the Sensonic not displayed on the SID.

Note

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


Diagnostic procedure


1. Connect a 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 Scan Tool.

If no message appears on either the SID or 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.
