Un-power steering

Thu May 04, 2017 3:49 pm

Today I was trying to parallel park in tight spot in carport and went several lock-to-lock cycles with the steering. SHOCKED to find I had burned off three miles of range doing this. So how can we disable the overkill power steering? I looked in book for fuse identifying it but nothing. My idea was to pull that fuse. There is a thread on here starting with forward shields down which did contain some pictures of the steering components as seen from underneath but they are missing. Has anyone pulled the power cable off the PS pump to see how many more miles we might get? One person stated he thought the car was light enough to steer manually and I totally agree.

Just because you lost 3 miles on the Range Remaining indicator, doesn't mean you actually lost any range. Get more accurate readings (from e.g. Canion) before you do anything drastic, at least.

I don't know anything about canion. Does it require a blutooth device plugged in to the OBD2 plug? How else could something know what the car was really doing? I have a spare one of those dongle things not being used.

yes, purchase an LX OBDlink dongle for $50 from scantool.net and download the android app, Canion, to monitor the voltage and current of the pack. It must be the real deal using the STN1110 chip, not a fake using ELM327, else it won't work.

Something else is going on - I can sit in the parking lot with the A/C running for half an hour waiting on the wife to finish shopping and not burn off 3 miles of range. No way the power steering is using that much . . . . unless you spent an hour trying to get it parked :lol:

I'm not sure what the computer would do if you disabled the power steering by pulling a fuse - Likely the car would fault and go into safety mode and only allow you to drive it at 20 mph to the nearest repair facility. The computer controls everything in this car - ABS, ASC (Active Stability Control), TCL (Traction Control Logic) - If Mitsu intended the car to operate normally without power steering, they would have given you a switch to disable it

While the Smart ForTwo has optional power steering (and if I were buying one, it wouldn't have it as that car is light enough to not need it), I feel that Mitsubishi did the proper thing by having power steering standard. It is just a tad to heavy to forgo it. Tight turning in a parking lot would suck without it.

I would say the 3 RR drop was a result of the total draw of the car systems, power steering, and the motor moving the car back and forth, and not solely because of the power steering.
