Fusion AWD V6-3.0L (2009)
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
OCSM
PINPOINT TEST F: THE OCSM DOES NOT RESPOND TO THE SCAN TOOL
WARNING: Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to
follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which
increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint
test.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
