S80 T6 L6-2.9L Turbo VIN 91 B6294T (2002)
-
central electronic module (CEM) connector terminal 5D (#B5)
-
SRS control module connector terminal 30 (#2B).
The resistance between a fault free cable and body ground should be infinite.
Checking for contact resistance and open-circuits
Check the connectors for the control modules. Check for contact resistance.
Check the collision sensor cable. Check for an open-circuit. Measure the resistance between all the connectors:
-
car-phone module (PHM) connector terminal A17 (#17)
-
central electronic module (CEM) connector terminal 5D (#B5)
-
SRS control module connector terminal 30 (#2B).
The resistance of a fault free cable is approximately 0 ohms.
Checking for short-circuits to supply voltage
Check the collision sensor cable. Check for a short-circuit to voltage. Use a voltmeter to take readings between the battery positive terminal and one of
the following connectors:
-
car-phone module (PHM) connector terminal A17 (#17)
-
central electronic module (CEM) connector terminal 5D (#B5)
-
SRS control module connector terminal 30 (#2B).
Remedy as necessary.
