This is the first of a three part videos on how the battery pack of this highlander was resuscitated.

Some years ago down town somewhere in Surulere, there was a terrible downpour, which wrecked havoc on properties, and possessions.

Unfortunately, there was a highlander that was parked on a low land area of the street, overnight. When the mornings came, owner had prepared set to go to work, but discovered the high voltage compartment had being flooded already.

The only fix was either to replaced the pack completely, or do some swaps. We opted for swapping some part of the high voltage system, and refurbishing the battery pack.

Disclaimer: Please if you're not comfortable working with HV systems, do not attempt this repair. You could be hurt, or even killed when messing around these systems.

This second video shows when we had finished the repairs, and awaiting installation in the car.

This is the final video of the repairs. After the installations was done, we decided to READY the vehicle. Immediately we got it readied, you'd be surprised what came out of the exhaust tailpipe.
Check out the video. So terrible. We had to get the radiator cooling system, entirely flushed, with clean water, before finally introducing Toyota super long life coolants in there.

Nice!

I believe the owner has learnt a huge lesson.

NEVER TRY STARTING A FLOODED HYBRID VEHICLE ! (Not even the ignition!)

If it was towed to your workshop,(without turning it on), the damage might have been a lot less severe.
