This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Case ground open
-
RCM
PINPOINT TEST D: THE RCM 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.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction
may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
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. See: Initial Inspection and Diagnostic Overview/Module Configuration/Inspection and Verification
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
