2000 toyota tundra battery light on. The 4x4 hi light is flashing and the truck wont shift the transfer case. An engine control unit ECU also commonly called an engine control module ECM is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. When the battery drains when parked the odds are that its the battery itself.
If your Toyota Tundras battery light is on it means a few things. Unscrew the negative cable on the battery. 2000 Tundra AC Just to be clear the Check Engine light and battery light coming on are not an indication of any problem.
Pop the hood of any Toyota Tundra and you may find a trusty battery installed by Firestone technicians. If voltage is not available check the integration relay or the tail fuse. It has some carbon build up and when the battery went dead the computer lost its learned values one of which is base throttle position.
Your 2000 Toyota Tundra needs a reliable battery to run optimally. Theyre coming on because the key is in the on position and the engine isnt running. Now its reset back to factory specs not accounting for a dirty throttle body.
Attach the other end to the cable you just removed. Put the key into the ignition and start the engine of your Tundra. Charging was 139V after battery replacement.
Take the cable off the terminal. Ya 75k is a little low for the alt to go out. Discussion Starter 14 Jun 24 2014.
