Paul...you are quite observant. "Yes", I have "concerns" when it comes to certain auto dealerships who compensate Service Dept. personnel based on "commission only ", etc...(which is the case here). They are incentivized to generate as much service revenues as possible....while my objective is to find the quickest, most cost-effective solution to the problem.
As an example....I had a recent issue with my tire pressure monitoring system whereby the symbol on my guage stayed lit...even after confirming proper air pressure, etc... Took the vehicle to the local Toyota dealer, paid $47.50 for diagnotics and was quoted in excess of $400 to fix the problem. I carried the vehicle home, unhooked the battery cable so the on-board computer would clear all signals/messages would reset. Kept cable off battery for 30 seconds, hooked battery cable back up. Problem solved....no more issues.
Thanks for your post and hope someone can provide assistance or more info with my problem with the Multi-information system.
