Pretensioner Control Module Internal Faults - Aston Martin DB7 Workshop Manual

Electrics
Seat Belt Pretensioner
Check the continuity of the line from pretensioner
control module pin 2 to instrument pack green
connector pin 2.
If continuity is approximately OQ, go to step 5.
If the line resistance is significantly greater than OQ,
service the wiring as necessary. Reconnect all
components and test the vehicle to ensure that the
problem is resolved.
Ifthe lamp and wiring checks are good, the fault lies
in the instrument pack or in the control module.
Replace the control module and retest. Ifthe fault
persists, replace the instrument pack. Reconnectall
components and test the vehicle to ensure that the
problem is resolved.
