That was not my idea, I just added info on ways to exfiltrate the cart  If you use those toggle switches make sure they're mounted high enough that you won't learn what they feel like jammed between your femur and patella if you get in a wreck. It's scary how many people will mount pointy things like that on the lower dash panels/knee impact panels and not realize what they're signing up for.

Knee-impact alone is why I use Carling-style switches in my TJ despite their obviously inferior appearance and feel to some giant toggles. Three of them are aimed squarely at my right patella.

I'm not too concerned about wrecking my patella. I usually can't get it anyway because I'm allergic to shrimp. The toggle switches will be mounted on top of the speedometer housing. They're on the far side of the airbag, so it should be safe-ish. Quick mock up of the bracket to hold the toggle switches. I need to go measure my dash carefully so I can replicate the curve of the dash on the bottom of the bracket. Also need to add a few more tabs to mount the two control relays and some connectors.   p.s. Hey xometry, why you don't stock galvanneal? I suppose I can spec it and see what they say. It'd be nice if their quoting engine could price it, though. e: I should offset the center mounting tab, so the middle toggle doesn't obstruct that screw hole. ryanrs fucked around with this message at 17:05 on Sep 29, 2021 |

Vetoing switch covers. These switches are for lights, not safety-critical functions. They should be easy to use. While I'm adding stuff to the dash, a nice quality of life improvement would be a two-axis inclinometer to help level the van when setting up camp. This can be surprisingly difficult to do in the dark on a bumpy surface. I do not care about measuring +/- 30 degree grades. This device would need to accurately measure in the 0-3 degree range. Maybe a tachometer, too.

According to McMaster, the cheapest one of these has a sensitivity of 0.157" / 1ft, which, if my high school trig serves me well, is about 2/3 of a degree out from level. I'm not sure if that means getting the bubble within the circle is 2/3 of a degree out from level or what, but I bet that you'll affect "level" more by climbing around in the van.

OK, well that's good enough to level the van. I should probably just get a bubble level like that. OTOH, I just grabbed this on ebay. I was thinking of driving it with a microcontroller + accelerometer. One toggle switch to select pitch / roll, and a second for x1 / x0.1 degree gain. So you get +/-25 deg for driving, and +/-2.5 deg for leveling. Or maybe +/-5 deg for leveling, it doesn't much matter what the numbers on the meter read since you are going for null.  Another possibility for that meter: tap the front ABS sensors and show relative wheel speeds. Meter swings toward the wheel that's slipping.

Definitely the latter. The former involves firmware for no reason and as such the project will progress until it's time to write firmware which is not fun so it will be abandoned*, like you were saying two days ago. The latter can be done in all hardware if you really want, and is cool as hell so worth doing firmware for. * Let's not talk about how many of my projects are currently at this point, it's an uncomfortable discussion ok? kastein fucked around with this message at 22:09 on Sep 29, 2021 |

Have no fear, all this analog meter stuff is just to see if I should reserve some space in the dash for the meters and some extra switches. That way the firmware doesn't slow down the project, because right now "the project" is just getting the light switches working. Later on, I'll build the microcontroller part when I'm fed up with staring at the non-functioning gauges. And as long as we're contemplating loving with the ABS, I would like a switch to disable it. The ABS fuse is a 60A monster, so I guess I'd need a big relay for my remote ABS kill, although there are probably better ways to do it. I particular, I'd sure like to disable it selectively under 15 mph. The ABS system really only misbehaves when descending rocky trails where the tires are slipping on gravel or scree. Classic scenario is descending a steep switchback, the ABS will kick in as the front tires slide around at 3 mph. The ABS just kinda gives up on the brakes and lets the wheels roll a little. That's super dumb at these speeds. Fortunately, the ABS module is surprisingly basic, so I think I can trick it pretty easily. My base model Sienna does not have the VSC / traction control stuff that came in the higher trim models. ABS inputs: - speed sensors in each wheel - brake pedal switch - transmission Park switch - transmission Neutral switch ABS outputs: - some dash lights - speedometer - solenoid valves are internal I think the ABS module would chill out if I made a circuit that disconnect the brake switch input when moving under, say, 10 mph. This won't affect the brake lights, which are not controlled by the ABS ECU. My switch would select between 'stock ABS behavior' or 'no ABS at slow speeds'. I'm not super into the idea of disabling ABS entirely. I'm also not excited to pull fuses every time I hit dirt, though I guess I could make it part of my air up/down ritual.

Later on, I'll build the microcontroller part when I'm fed up with staring at the non-functioning gauges. Generally, if the ABS controller doesn't see one of the sensor inputs, it disables ABS. An old Subaru trick is to wire a switch inline with one of the sensors and toggle it when off-road.

Hmm, and the sensor fault would light up the ABS warning light on the dash, which seems like a feature. This is a good idea! Dunno if the ABS system will like being toggled every time the vehicle speed dropped below 10 mph, so it would probably be a real switch, not a speed-based thing. And I guess you probably have to restart the engine to get the ABS to start working again, right? Or does it come back as soon as you flip the switch back on? ryanrs fucked around with this message at 23:57 on Sep 29, 2021 |

That's what I was wondering too and was about to post. I would definitely try just unplugging a sensor (drive if necessary to trip the light) and reconnect and test it before doing any wiring. I would recommend making sure the abs does work even if the light goes out. Its probably good but computer programs can be touchy.

Oh man, I feel guilty before I even suggest this, but since it's for off-road anyway ... maybe kill the brake pedal switch? Bonus credit for resetting it at power-off (or above a certain speed) and for routing it via separate wires to the brake lights. I think it'd work. I mean, I'm not 100% sure, but if it's non-TC, it shouldn't trigger ABS without detecting the pedal pressed.

You can cut the brake signal to the ABS ECU without losing your brake lights.

Speedo no, but navigating by odometer-based distance is a good thing to keep working in the event any GPS-based solution fails.

Aren't the speedo and the odometer typically separate things? I'd be surprised if the Sienna was designed such that an ABS fault would let the odometer be wrong.

That depends on the car I suppose. I had a t-bird with a flaky speedo and if it wasn't registering the odometer wasn't either.

Safety Dance posted:Aren't the speedo and the odometer typically separate things? I'd be surprised if the Sienna was designed such that an ABS fault would let the odometer be wrong. I don't think there's another source for wheel pulses. The cruise control also gets its speed info from the ABS ECU. I don't see any pulse output from the transmission, for example. The 1st generation, base model Sienna is not a complicated car. Take the brake lights: No ECU controls them. They aren't even on a relay. Toyota just runs the full lamp current runs through the pedal switch. I'm 95% sure that if I put a switch in the brake signal going to the ABS ECU, it'll go idle and ignore the wheel signals altogether. But I don't want to cut up my ABS wiring harness to test this theory right before the van has to drive to the fabrication shop. I will, however, reserve a dash switch for this function.

Apparently there IS a trans speed sensor under the battery and air box:  Despite the accent, I'm pretty sure this guy is in the US and the Sienna in the video is a USDM one (Sensor location in the video is around 3:20): https://www.youtube.com/watch?v=veu-noYIOCo&t=200s E: poo poo, maybe not, the earlier ones (99-00, I can't remember the MY of yours) apparently have a blanking plug for the speed sensor port, as described in post #4 in this thread. I probably should have kept reading before posting.

OK! I just dug through 3 months of old mail to find my new DMV tags. Monday morning I drive out to Sacramento to drop the SIenna off at the fabrication shop. I will include a dozen doughnuts, a case of red bull, and a flat of Mexican coke. The bumper will be made from steel tubing, with some kind of grille made of cnc plasma-cut aluminum. They will send pics to me for feedback as they build. It'll take a week or so.
