PINPOINT TEST AB : RESTRAINTS CONTROL MODULE (RCM) NOT
COMMUNICATING WITH THE FORD APPROVED DIAGNOSTIC TOOL

WARNINGS:

The backup power supply must be depleted to prevent the risk of accidental airbag

deployment. After disconnecting the battery, wait at least 1 minute before starting work
on the supplemental restraint system. Failure to follow this instruction may result in
personal injury.

In order to prevent the risk of accidental deployment, do not program any keycodes

while working on the supplemental restraint system. Failure to follow this instruction may
result in personal injury.

Only test the connectors of airbags or other supplemental restraint systems using

the correct test probe adapter. Failure to follow this instruction may result in personal
injury.
