If Inspecting With The Connector Disconnected < When Inspecting A Female Pin>

Required Special Tool:

MB991219: Inspection Harness (Included in MB991223, Harness Set)
The special tool MB991219 for connector pin contact pressure should be used. The test probe should never be forcibly inserted, as it may cause a defective contact.

From back side of the connector (SRS-ECU harness side connector)
Since the SRS-ECU harness connector is plated to improve conductivity, observe the warning below when checking this connector.

WARNING: Insert the backprobing tool into the connector from the harness side, and connect the tester to the back-probing tool. If any tool other than the backprobing tool is used, it may cause damage to the harness and other components. Furthermore, measurement should not be carried out by touching the backprobing tool 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 backprobing tool, the plating may break, which will decrease reliability.
