Hello Guys:
I had a series of Hybrid Battery errors in my GS450H (New to me) 2006 Model.
Basically issues with Cells in Bank 13 and 19/20 according to a code scanner.

I've removed the Hybrid Battery as per the Instructions available at various locations, and replaced 2 x Cells which had Low Voltage (6.7V Compared to 8.35V on the rest of my Pack).
Re-Assembled the Battery and connected back in car.

However now when I try and start the car I get nothing... pressing the start button does nothing... the Key Remote doesn't respond and lock/unlock the doors at all (even though I can see the light flashing on the Remote).
My Mechanic and I have trawelled various forums and completed the following

- Place Remote close to the Start Button (No Change)
- Disconnected Battery for an Hour or Longer (We had it off for 15 Hours and still no change once reconnected)
- Checked Engine Bay Fuses (All Seem Ok/Working on Test Light etc)

The Car does have 12V Power running through it, the Headlights work through the stalk, and the Interior Lights come on when you open/close doors. Central Locking appears to work with the Key (obviously not remote).

Does anyone have any ideas at all?

Should the Dash come on/Light up even if the Hybrid Battery Pack was disconnected/not working?

Reopen the battery and check to see maybe you missed a connection

Guys problem has been diagnosed and resolved today. I haven't been onsite with the Mechanic but the Large Fusible Link beneath the Fuse Box in the Engine Bay had blown (I believe it's 60A). We've replaced it temporarily whilst we wait for the correct Lexus Part and the car is functioning perfectly.

Also my Battery Replacement of 2 x Cells of the 40 has also resulted in my Hybrid Battery Errors going away..

Good result all around in the end..

How much did those replacement cells cost you and where did you purchase them from, maybe to help others that have battery issues

BCTS

cells were around $60AUD Each... so around $40USD (I'm in Australia)

they are the same as used in Prius Gen 2... so fairly readily available...

Hi BCTS, I'm having a similar issue with my 07 GS450H. I replaced a bad cell in the hybrid battery pack and now the car won't start at all. I do get lights on the dash and other electrical items work. I get the Check Hybrid System and Check VSC, Check EBC. I also see some power level on the hybrid battery dash screen. I have plugged in the orange service plug and slide it over to the left as far as I can without breaking it.

I took the 12V battery to AutoZone to recharge. It was at 11.6 and now its at 12.6

Any suggestions?

Could you post which fuse it was and where its located?
