2008 Toyota Highlander: Symptoms after Jumper Cables Crossed?

This is not Advisable.The Jumper cable crossed will cause lots of shorting issues.Tracing the exact problem takes lots of time in some cases.
Basically in some cases,you will see that vehicle will drive only in idle but will give no response on throttle.

The first thing that gets affected by this is,it normally just blows fuses. The large 120 amp ALT fuse.
If there is no throttle response more than likely you also popped the 10 amp or possibly 15 amp ETCS fuse look in the fuse box under the hood and locate this fuse. This is the main power feed for the drive by wire throttle motor. If there's no throttle response most of time of the time you will find that this fuse is blown.

Typically when these are jumped backwards like this it only blows fuses it rarely does any damage to engine control computer's.. Replace it see how it drives then check for any other components that are not operating and inspect the rest of the fuses.
If you notice any other problem after that,then in most cases the check engine light will come ON steady.Whenever the check engine light illuminates by default the vehicle skid control light comes on also.

This details will help.
Thanks.

2008 Toyota Highlander Hybrid: Warning Lights Abs, Vsc & Brake Are On?

VSC/Brake/ABS Lights Coming ON.
This types of problems are noticed on many Toyota Highlander models.
Basically in this types of cases you will notice that  motor/pump sound/noise coming from the right front of the engine everytime car is unlocked.Many car owners dont understand this problem.

First thing i will say on this case is get the error codes retrieved from cars computer.
There is manual procedure to retrieve the error codes by jumping the pin/wires.

In most cases the Error codes Received is
(ABS) - 42, 98.
(!) - 36, 66, 69.

If you receive Error code 69 then its problem here.

THE CODE 69 HAS TO BE THE FOCUS. This means there is a fluid loss or the Accumulator which is part of the ABS actuator and VSC unit is leaking internally. This is why you hear the motor buzzing. It is trying to pressure up the system and can not. More then likely the actuator assembly will have to be replaced if there are no visible external brake fluid leaks. The other codes all have to do with reinitializing the system and calibration issue caused by the failure of the accumulator pressure.

One more important  detail.The ABS actuator has nothing to do with the hybrid system. Provided the brake pedal pressure feels normal and the stopping ability feels normal you should be fine to drive. However if it's an accumulator leak internally in the actuator it could cause intermittent low or no brake pedal effort. At this point would be unsafe to drive. The ABS actuator normally houses the accumulator on US model made Vehicles.
On other Country made vehicles the Actuator is separate from the pump and booster motor assembly.

This details will help.
Thanks.
