Immobilizer unit is connected in series with the neutral safety switch.

Next time your Luxes GS fail to start.....put you foot on the brake,shift to NEUTRAL (N) and turn the key.

A shorting/shorted neutral will draw power and kill the battery.

Give it a try.

Please post result on the comment window.

Alternator not charging battery on Lexus gs300-1998.No battery signal. All other warning signals appeared. Car started right up after a jump,cut back off less than 500 feet away. What can it be?


1. Remove the battery and put it on a charger overnight, see if it holds a charge. If not repair the battery.
2. If the battery holds a charge, replace or repair the alternator' Good chance the brushes need replacing.

Clearing the codes is simple that is done by removing the fuse of the EFI from junction box 2 for 10 seconds. Make sure to remove the jumper wire and switch the key off before clearing the codes.

Code 12 and Code 13 Rpm signal circuit fault
Code 14 Igniter signal circuit fault
Code 16 ECT control signal fault
Code 21 and Code 28 Main oxygen sensor fault (for ES300; SC300 & GS300 models)

Code 31 Low airflow meter voltage (for ES300 and GS300 models)
Code 32 High airflow meter voltage (for ES300 model)
Code 35 Barometric pressure sensor circuit fault (for GS300 & SC300 models)

Display dim after battery died


you should first have the alternator tested. any auto parts store will test your alternator and battery for free. Also you should remove the battery cables and clean them with a battery terminal cleaner. sometimes a loose or dirty connection at the cables will cause the battery not to charge properly.

My lexus sat for about 3 months and i tried to start it with a battery charger and it will start but wont idel


Hi there,

Erratric idle is normal, after the battery has been flat for some time.

Your vehicle's ECM monitors many emmission sensors and stores their appropriate data parameters. When the ECM loses power (i.e. the battery goes flat or is disconnected), all sensor data is lost, so the ECM then reverts to factory parameters, until the ECM re-learns new engine sensor parameters.

If you can get the engine started and leave engine idling for approx. 15 minutes (for engine to reach operating temperature), then take for another 15 minute drive (city driving is best), this should be sufficient for the ECM to re-learn new parameters and stabilise the idling.

If the engine still will not idle correctly, then have the OBD fault codes read from your vehicle's ECM - this will quickly identify the suspected circuit causing this condition.


Hope this helps............

Ive got a lexus gs300 with a flat battry ive conected jump leads to a van left it running for 5mins the lexus is trying to turn over but will not start


When a battery goes completely dead. it needs replaced. you can jump it but you will have to leave the jumpers on for about 30 minutes to get the battery to hold enough charge to start. revvingthe other engine doesn't help, it only puts out so much voltage.
