battery light 2006 Highlander stays on ???
Have alternator tested light is saying alternator is not charging.
Make sure you still have the drive belts before driving, if they are all there then have the charging system checked, hopefully it is not an ECM failure.
firebird338 is spot on right. Your battery is not accepting a charge, far most likely culprit is alternator but could be bad battery, if it's old..as in over 4 - 5 years
tennisshoes and I were posting at the same moment. But he is also hit the proverbial nail. The ECU in the mid 2000's... 2003 to 2008 to be specific, were prone to failure in Toyotas. My '06 Corolla was re-called for that. Good call 'shoes
Hope the alternator is easy to replace !! Just did my sons in his Jeep, I must be a master mechanic now right ? Thnaks
The video is actually pretty good... these guys are from the deep South and the accent is so cool
On the right hand side of the battery looking towards back of car there are two plugs One has nine wires. Pull this plug apart and look at the male ends and see if you aren't missing one Mine rusted off on the white wire with blue tracer and the battery light always stayed on I cut the two wires and attached a jumper wire between the two and the light finally went out
