Loose Wiring Connection Diagnosis With NGS Tester

To confirm a break in the wiring or a poor connection between a blade and terminal at a connector, use NGS Tester to test the RAP module inputs with the following steps:
1. Connect NGS Tester.
2. Turn the ignition switch to the ON position.
3. Select the vehicle type, Data Link, RAP, ACTIVE COMMANDS.
4. Select PIDLATCH.
5. Select PIDS.
6. Select the input to be monitored, LATCHIO, and then START.
7. Press or activate the switch on the circuit in question and keep it in its active state. LATCHIO counts the number of times that any input or output changes state. All other inputs will lock on the first change in state that is seen while on this PIDLATCH screen.
8. Wiggle the wire at the point where connection is questionable. If there is a loose connection, the LATCHIO number will increase quickly as the wire is wiggled.
