What Every Montero Owner Should Know When Getting Emissions (smog) Dyno Testing
 

I recently had issue getting my smog certificate with my 03 montero in california. The emissions testing requires a dyno run. The montero traction control would kick in sensing there was a problem that front wheels were not rotating on the 2 wheel dyno. According to the CA booklet on smog, the smog tech should be able to deactivate traction control by manually shutting off skid contol by pressing the button on the center console. Even with skid control off, dyno run could not be completed.

I consulted the Mitsu TSBs and found that 03 and 04 monteros actually have a skid control and traction control as 2 separate systems. THe only way to shut off traction control is to pull the ABS fuse. See TSB 04-00-0017. Once the fuse is pulled the dyno run could be completed.

Apparently 03 and 04 monteros must be done this way for dyno runs.

Thanks tj - good info.

tj90 - great info. I have the 96 and wonder about that center console switch saying "A/T" and displaying "Power" and "Hold" next to the 4x4 lights in the display. Can you explain it's function to me, please? Thanks

Sorry I dont know what those buttons are for!

In "Power" mode transmision should upshift at a higher rpms thus giving you extra "power".
I think when you put it in "Hold" and select the gear, the car will stay in that gear. Transmision will probably downshift anyway if, let's say, you stop the vehicle.
