Power Relay Test

Power Relay Test

Special Tools Required

- Relay Puller 07AAC-000A1A0

Use this chart to identify the type of relay, then do the test listed for it.

NOTE:

- For the turn signal/hazard relay input test Turn Signal/Hazard Relay Input Test.
- PGM-FI main relay 2 contains a diode between terminals No. 3 and No. 4. Power (+B) must be connected to terminal No. 4, and ground connected to terminal No. 3. Failure to test relay correctly will damage the relay and the PCM.














Normally-open Four-terminal Type

Check for continuity between the terminals.

- There should be continuity between terminals No. 1 and No. 2 when battery positive terminal is connected to terminal No. 4, and battery negative terminal is connected to terminal No. 3.
- There should be no continuity between terminals No. 1 and No. 2 when power is disconnected.










Five-terminal Type

Check for continuity between the terminals.

- There should be continuity between terminals No. 1 and No. 2 when battery positive terminal is connected to terminal No. 5, and battery negative terminal is connected to terminal No. 3.
- There should be continuity between terminals No. 1 and No. 4 when power is disconnected.
