One Touch Down Relay Inspection

ONE TOUCH DOWN RELAY INSPECTION




Perform this test when directed in the diagnostic pinpoint tests.
1. Measure resistance between terminal 2 and terminals 1, 3, 4, and 5. If resistance is 5 ohms or less between terminal 2 and any other terminal, replace the relay. If resistance is greater than 5 ohms, go to step 2.
2. Use two jumper wires to connect terminals 1 and 3 directly to the positive battery terminal. Measure voltage at terminal 4. If there is no battery voltage, replace the relay. If there is battery voltage, go to step3.
3. Connect a third jumper wire to terminal 2 and a known good ground. Measure voltage at terminal 5. If there is no battery voltage, replace the relay.
