HINT

Read freeze frame data using the hand - held tester. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

Standard: 0.2 to 3.0 ohm at 20°C (68°F) Check the fuel pump operation Apply battery voltage to both the terminals. Check that the pump operates. NOTE: These tests must be done quickly (within 10 seconds) to prevent the coil from burning out. Keep fuel pump as far away from the battery as possible. CAUTION: Always turn on and off the voltage on the battery side, not the fuel pump side. NG: REPLACE FUEL PUMP (See «REPLACEMENT»(ref-209388-S40611939062005121000000) ) OK: Go to next step.
