< When Inspecting a Female Pin>
- From front side of the connector
Required Special Tool:
MB991219: Inspection Harness (Included in MB991223, Harness Set)
The inspection harness 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 backprobing 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.< When Inspecting a Male Pin>
CAUTION: At this time, be careful not to short the connector pins with the test probes. Doing so may damage the circuits inside the ECU.Touch the pin directly with the test probe.
