Question edited for clarity.
Question moved to model category.

You can't, it is run by the ECM. Just test the fuse and the fuel relay.

I only know of engine service message
clearance using the mode buttons on a VT.VX

i hope you are a lucky person because
any commodore transmission man or auto
driven without fluid would have taken some internal damage

Not fimiliar with commodore engineering (im from the US, we dont have those!) but follow the upper radiator hose to where it connects to the engine, theres the thermostat. Remove everything thats in the way of removal, swap the thermostat then reassemble. Sorry if this is to vague to help, but for some people, this would be the only clue they need to just hop into it!

Follow the below steps to remove the alternator from RX 350.
1) Disconnect the negative battery lead from the car battery terminal and remove the engine cover to access the alternator and accessory drive belt.
2) Loosen the 14 mm bolt on the accessory drive belt tensioner pulley. Take the free hand and grasp the belt while pulling away from the tensioner pulley. This will release the tensioner pulley and allow the belt to be removed.
3) Disconnect the electrical plug connected to the alternator by prying the locking tab loose with the regular screwdriver.
4) Remove the 14 mm through bolt from the alternator using the 14 mm wrench or socket. Support the alternator with the free hand until bolt is removed completely. Slide alternator out of the engine bay.

Have your starter checked. Mine did the same thing. In the beginning it was slow cranking over. Then it just stopped turning over all together. Is it a stick or automatic? If stick get a push start from friends if it runs fine then you know it's the starter. Good luck hope this helped.

Are these guys SERIOUS??




The alternator is accessed from UNDER the vehicle LEFT SIDE facing the engine bay.

REMOVAL & INSTALLATION




1. Disconnect the negative battery cable.

2. Loosen, but do not remove the alternator adjusting nut.

3. Turn the front wheels completely to the right, then raise and safely support the vehicle.

11. Holding the alternator in one hand, remove the adjustment nut then slide the alternator off the T-bolt. The T-bolt does not have to be removed. Lower the alternator and remove through the wheel well.

12. You may need to use a C-clamp to drive the sleeve into the mounting ear for installation clearance.

13. Position the alternator in the vehicle, sliding it onto the T-bolt. Install the adjusting nut.

Disconnect the battery negative cable.
Remove 12mm (3) and 14mm (4) bolts holding skidplate on and remove skidplate
Loosen the 14mm nut on the tensioner, then unscrew the tensioner adjuster bolt until the belt can slide off.
Unplug the alternator electrical connector.
Unbolt the alternator cable lug (12mm or 13mm depending on alternator manufacturer)
Remove lower 12mm bolt
Remove upper 14mm pivot bolt
Use large screwdriver to pry alternator off bracket, it pinches on when the pivot bolt is tightened.
Drop alternator out bottom of engine bay; helps to unbolt or bend transmission cooler lines out of the way.

The steps to replace an alternator are:

1. Do the following through the passenger side of the engine bay of course with the hood up.
2. First and most important is to disconnect the negative connection to the battery (driver side).
3. Using a 12mm socket loosen the tension adjusting screw and bracket screw. Using a 10mm socket or open end remove wirings. Pinched other connector to remove.
4. Using 14mm socket with 3/8 drive ratchet remove the big bolt on the lower side of the alternator.
5. You might need some help from a pipe for extra leverage.
6. Remove all parts that will hinder the removal of the alternator.For example the charcoal cannister on the firewall just slide up.
7. Ease the alternator through the opening by turning the alternator untile it can pass through the opening.

push in the button on the left headrest post and use a small piece of coathanger wire and do the same to the other headrest post. There is a small hole in the side of the plastic. Now pull up on headrest whilst doing this and it should come out.
