Hi everyone,

This has been an ongoing issue for me, but car performance does not seem impacted.... Brief history.

2010 ES350... Was detailing interior of car, and didn't realize headlights were on. Eventually, battery drained and car would not start. Had OEM, original battery installed at the time. No dashboard lights lit prior to this.

From what I recall, shortly after replacing the battery and getting vehicle started, my slip indicator was solidly lit on dashboard. No other lights are illuminated, and vehicle appears to behave the same.

Fast forward to today, my OBD II scanner (Innova) does not pick up any current DTC's. There are readiness codes stored, but I understand that these are merely emmission related. However, there are historical codes stored which I am concerned may be possibly contributing to the dashboard light. The codes are P1604 and B2799. These appear to be related to the immobilizer system on my ES. I've tried to clear these codes, but they won't go away, so I suspect something is still tripping this. Keys are fine, just changed the FOB battery out a couple of times. I may try my second set of keys to see if it fixes this mess.

Since my OBD scanner doesn't support ABS, I'd like to see if AutoZone or something of the like can help me detect if there are any codes being thrown by the ABS system. Not sure if this is what is tripping the SLIP light.

I'm hoping someone out there has some advice for me. I'd appreciate if anyone can please share some suggestions or provide any help with this?

apparently there is a way of turning the traction control on and off by pumping brakes etc

I believe the 2009 and newer cars have a button to turn off and on the traction controler

Yes, my ES has a traction control disable button and I did try to disable/re-enable the traction control, but that didn't help unfortunately. Thanks for the idea. Any other suggestions?

How about this? It's for the RX but may apply to the ES too.
