power mode

[WormGod]

I had this happen a few years ago. I was also in the middle of doing some stereo work and had the battery disconnected for a couple hours. Upon reconnecting the battery, the light worked fine.

Maybe the brains need a battery reflash? *shrug*

Worked for me.... worth a try for starters. Seemed to be an isolated, freak incident, but it has not returned.

"you won't necessarily feel a difference in power -- it just changes where the shift points are."

Absolutely.

The only time I've used mine was while towing. The change in shift points helped to downshift on hills - made a big difference. Soooo....

Try a hard acceleration from stop all the way up to cruising speed with the switch off. Try it again with the switch on. Pay attention to the shift points & look for any change.

Other than that, I'll second the motion to do a computer reset first since that's easiest. Just disconnect the battery for 30 minutes - reconnect & try 'er out.

Second, check all fuses (next easiest)

Third, start tracing the wires from the switch to the computer looking for broken or frayed wires or loose connectors.

After that, I haven't a clue.

Be sure to post whatever you find.

I honestly have to disagree with the sentiment that you do not feel a power increase. When I drive in Power Mode, especially at highway speeds, I feel a much faster response time when I accelerate, as well as faster acceleration.

Well, maybe I said that wrong. It doesn't make the engine any more powerful, it just keeps it in a lower gear for longer, and drops into a lower gear more easily.

Aside from the idle test, the other place you will see the power button do anything is when you're on the highway, climbing up hill. If you punch the power button then, the transmission will drop into a lower gear. If you turn the switch off, it will drop back into high.

When power mode is off, the shift points are too conservative, in my not-so-humble opinion -- especially at highway speeds. You really have to stomp on the pedal to get it to downshift. So, I usually drive with power mode on. I like it to just GO when I press the gas. I don't want it to sit there and ponder.

No power button:
"Go!"
"Give me a second...I'm sure I can get an extra 5MPH from this gear..."
"Yeah, but it'll take you a half mile and the better part of a minute! I need to pass this guy NOW, before I get blocked by the guy with six tons of hay on the trailer!"
"Okay, okay, I suppose I'll drop into passing gear..."

Power button:
"Go!"
"Gone."

That is what I mean!

Yeah,

Whoa - what was that black streak that just went by...

Must be on his way to Moab...

But why was he wearing a gasmask?

Sorry - killing time waiting on a phone call

Well, not quite THAT fast!
