NOTE:
TERMINAL VOLTAGE TABLE (REFERENCE)
2008 Mazda CX-9 Grand Touring
The BSM control module connector cannot be connected to a tester
due to its water-resistance processing, therefore the short wiring
harness connector is used for measuring the terminal voltage.
If the terminal voltage is not as indicated in the table, inspect the
short wiring harness connector for continuity. (See CONTINUITY
INSPECTION OF SHORT WIRING HARNESS CONNECTOR.) If the
short wiring harness connector is normal, inspect the parts under
"Inspection items".
If the system does not work properly even though the parts or
related wiring harnesses do not have any malfunction, replace
the BSM control module.
