Resistance Inspection

Caution
•  If a tester lead is inserted forcefully into a terminal during resistance measurement, the terminal may deform and cause a decrease in the contact pressure between terminals while the connector is connected. When measuring resistance, attach a tapered lead or wire to the tester lead and lightly touch the terminal with the tip.

1.  Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION [13B-MSP].)

2.  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [13B-MSP].)

3.  Disconnect the negative battery cable.

4.  Remove the fuel pump resister. (See FUEL PUMP RESISTOR REMOVAL/INSTALLATION [13B-MSP].)

5.  Verify that the continuity between the fuel pump resister terminal A and B is within the specification.
