This is a common problem with these cars. I have had it come on also a couple of times. No need to worry unless it stays on.

Hi
1. Possibly your battery is on its way out.( Heavy Discharge Test will confirm this )
2. Your charging system is poor, ie:- Alternator belt is loose or the alternator is on way out, or you have a bad connection to the alternator.
Most usually its a loose alternator belt.
Good Luck !
John.

1991 Cressida How do i know if my alternator is bad?


if the alternator is not charging , there will be a red battery light on the dash
reasons for engine stopping are
broken timing belt/chain, cam/crank position sensor failure
immobilizer activation
ignition control module failure
run the fault codes as some engine lights only light up for urgent problems that require you to stop the engine

check the drive belt for condition and tension as you drove on the battery only because the alternator was not working . The battery you replace was a good battery just needed charging. Putting the car in gear lowers the rpm's below that necessary to spin the alternator fast enough to keep the light off . When the alternator is needed the drive belt of some other failure in the alternator comes into play . have it checked out at an accredited auto electrician

Charging system failure


Most probably the alternator brushes are worn.
My second guess would be either the alternator's voltage regulator or bridge.

Although the computer said "charging system failure", you were able to drive the car, but all the electrical systems (headlights/taillights, power control unit, injectors, ignition etc) were powered by the battery current instead of the alternator current. The alternator wasn't able to recharge the battery and power the devices due to its failure.

After a couple miles you've discharged the battery to a point where its voltage was insufficient to power the instrument cluster (thus the speedo and fuel meter went down to zero). The engine's computer, injection, ignition and, let's call it "airbag controller", are far more critical for the passengers' and vehicle's safety and therefore were still able to work despite the battery voltage being so low. But some time later the battery was discharged to the point it was unable to power these most critical devices and the engine stopped.
