6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into connector from harness side (rear
side), and connect the tester to this probe. If any tool than special is used, damage to the harness
and other components will result. Furthermore, measurement should not be carried out by touching
the probe directly against the terminals from the front of the connector. The terminals are plated to
increase their conductivity, so that if they are touched directly by the probe, the plating may break,
which will cause drops in reliability.
