Pedal Positioning Relay: Testing and Inspection

Power Relay Test




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.
- PGM-FI main relay 2 contains a diode between No.3 and No.4 terminals. Power (+B) must be connected to the No.4 terminal, and ground connected to the No.3 terminal. Failure to test relay correctly will damage the relay and the PCM.




Five-terminal type
Check for continuity between the terminals.
- There should be continuity between the No.1 and No.2 terminals when power and ground are connected to the No.3 and No.5 terminals.
- There should be continuity between the No.1 and No.4 terminals when power is disconnected.
