Parasitic Draw Inspection
- Verify that the ignition is switched off.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)CAUTION:
- Operating electrical loads while the parasitic draw is being measured can damage a series-type ammeter.
- Monitor the current draw.NOTE:
- If the battery is not left undisturbed for 10 min, the tester will indicate a high value (approx. 300 mA).
- If the push button start or any electrical accessory is operated after the tester is connected, the battery must be left undisturbed for 40 min or more from that point.
- For vehicles with the immobilizer system, the system periodically shifts synchronization of the security indicator light flashing. Therefore, 65 mA (0.1 s) current draw is supplied when the security indicator light is illuminated, and 40 mA (2 s) current draw is supplied when the security indicator light is not illuminated. In addition, the measuring instrument, which shows the average value, indicates around 55 mA.
- Leave the vehicle electrical system undisturbed for 40 min or more, and then measure the parasitic draw.
- If electrical devices (accessories) are installed, measure the back-up current while removing the electrical devices (accessories) one by one.
- If not within specification, measure the parasitic draw while removing the fuses one by one from the inside of the main fuse block and the inside of the fuse block.
- Inspect and repair wiring harnesses and connectors of the fuse where the current draw has decreased.
