Note: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals.
Frontprobe
Disconnect the connector and probe the terminals from the mating side (front) of the connector.
Caution: Do not insert test equipment probes into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal can cause a poor connection, which can result in system failures. Always use the J 35616 GM-Approved Terminal Test Kit in order to frontprobe terminals. Do not use paper clips or other substitutes as they can damage terminals and cause incorrect measurements.
Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors:

Backprobe
Note:
• Backprobe connector terminals only when specifically required in diagnostic procedures. • Do not backprobe a sealed (Weather Pack®) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector. • Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe. • After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact.
Do not disconnect the connector and probe the terminals from the harness side (back) of the connector.
