GS300 warning lights

[ScottC]

Hi

A friends 2005 GS300 is displaying the tire warning symbol and a 'system check' symbol.

A previous tire warning was accompanied with a low pressure warning and the problem was indeed a deflated tyre.

Handbook says the car can be driven and describes the fault as a problem with the electronics that monitor the tyre pressures,

rather than a problem with tyre pressures.

Any ideas?

Scott

would suspect that the TPWS in the tyre as the Battery as expired

needs dealer to find out which one

HI Robert

I didn't know that the 2005 GS300 has this, my 2005 LS430 uses data from the ABS sensors to detect tyre pressure changes

and I assumed the GS was the same.

I will pass this on.

Hi Scott, Have you physically checked the tyre pressure within each tyre? 

If the actual pressures are okay then maybe a sensor is on the fritz?

I'm not sure about the earlier GS but mine have dedicated TPMS sensors fitted to each wheel.

Have you recently added air to any/all of the tyres, that then generated the dash light? 

If so, then you may well need to reset the TPMS system.
