CHECKING THE RELAYS
Check each switch for continuity with the pocket
tester. If the continuity reading is incorrect, re-
place the relay.                                          1. Positive battery terminal

1. Disconnect the relay from the wire harness.
                                                                   (between “3” and “4”)
2. Connect the pocket tester (Ω × 1) and battery
   (12 V) to the relay terminals as shown.
   Check the relay operation.                         Relay unit (fuel pump relay)
   Out of specification → Replace.
