Tc3000 not calibrating

John Fehn on the tc 110v schematic pg36 of service manual I checked out the 8 pin connector that tells how much voltage is supposed to be coming out of the wires pin 1 supposed to be 5vdc I got nothing pin2 supposed to be 5 to 12vcd I get nothing Ive replaced the speed sensor still dont work when I start the calibration I can hear the click and it goes through whole cal. but nothing moves I dont know if I need a new mcb or if some place out there can rebuild them for a reasonable price thanks

Sounds like it's the controller. Those are very hard to find parts. Most repairs on Bowflex are nearly impossible after the machine is about 4 years old.

SOURCE: We are getting a E1 code on the display screen.

trace the jumper wire from the speed sensor over to the wiring harness. there is another, unused, wire that could have been connected by accident. The E1 error means the console isn't sensing the belt turning.

SOURCE: I just replaced my speed

speed sensor works by sensing the holes on the disk that pass through it's transmitter and reciever led's once the disk block the path of communication of the sender and reciever there is a count of one and the indicator green light will blink this means the sensor is working.if the green light is steady lit this means that the senors are blocked you need to check the it properly mounted,is there any materials blocking the sensor,,check for the voltage supply of the sensor there should be a 12v supply present.check the disk that the sensor read or the chain make sure that the sensor has a good reading distance...from the moving disk or is properly mounted...thank you.

SOURCE: Speed Sensor not working or something else?

Mine was saying the same thing however i checked that nothing was disconnected from the motherboard (MCB) especially in the back where the speed sensor wire is connected. I also had a hard time figuring out what to do with the Stiff business card but after looking at the diagram in the manual i figured where it was talking about. I fixed mine and ran a cal test and it passed. However now i am having problems with my belts getting stuck and i have also used treadmill lubricant. So I will have to look into it more to get my machine going as i have not been on it in a while now. Good Luck to you.

Error code E61 shows on my Frigidair Affinity washer. Do you know what E61 Means?

Hello Murray;

My name is Peter. I am a retired field service appliance technician.

Hi E61 means that the control board is sensing an incorrect/abnormal voltage present at its input.

1.) Unplug the unit for 5 minutes. If the error comes back -

2.) Lets check your power cord:

a.) Unplug the machine. Is the middle connector on your power cord connected to 'N'?
b.) Tighten all the connectors. Make sure you have a good ground.
c.) Check the voltage. Between 'L2' & 'N' = 110V, 'L1' & 'N' = 110V, 'L2' & 'L3' = 240V.

3.) Lets check your control board for shorts:

a.) The following link will show you how to access. Ground yourself by rubbing your hands on bare metal. Static electricity will knock out a board.
b.) Check all of the connections, push in on the wires at the connectors.
c.) Reassemble and try to start

4.) Well, if none of the above solved the problem, you have to replace the control panel.

Where is the vsc switch on a 04 4runner?

If you suddenly have the "VSC TRAC" and "VSC OFF" lights in your dash, this post may help you fix the problem yourself. The information here applies to 4th gen 4Runners that use the ISO protocol rather than the newer CAN protocol for their OBDII interfaces to code readers, ECU programmers, hand-held testers, etc. The OBDII interface includes several different protocols (methods of digital communication) and they all use the same physical connector, though with some different pins. The connector is located at the bottom of the dash on the driver's side and in the 4Runner it's covered by a small black cap.

4Runners switched from ISO to CAN around 2005 though this information may also apply to newer 4Runners with some modification. That is, newer 4Runners may display trouble codes and reset sensor calibration values in response to the connection of different (than earlier 4Runners) pins together than the ones described below.

Several posters have discussed similar problems, described in several different threads. I'm reluctantly starting a new one, with a more specific title (including the exact name of the two trouble indicator lights), in the hope that searchers will more easily find a solution.

The specific behavior: On startup, the "VSC TRAC" and "VSC OFF" lights come on and stay on. The ABS light may or may not come on. On subsequent starts the lights will come on temporarily as usual (as a bulb check) and then go off. They come on again and stay on as soon as the 4Runner is moved. The "check engine" light does not come on. This behavior begins after the vehicle has been hooked to some sort of OBDII code reader or engine tester or data logger, etc. Though the lights are on, no standard OBDII problem codes are detected by a regular code reader.

Cause: The code reader or other OBDII device has attempted to communicate with the 4Runner using the CAN protocol (involving pin #14) and this has caused the 4Runner to erase the "zero point calibration" numbers in its memory. Without these numbers it can't get accurate information from the yaw rate and deceleration sensors (in the center console near the gearshift) and so it disables traction and stability control functions.

The fix: Perform the "zero point calibration" procedure as described in TSB BR001-04. This procedure can be performed without special equipment such as a hand-held tester or OBDII reader. You only need the equivalent of a jumper wire to short together two pins of the OBDII connector at the right time and the right number of times between switching the 4Runner on and off. More detail is included below, leveraged from my other posts.

Why this doesn't happen every time a code reader is used: The code readers usually use the pins and protocol of the OBDII connector in a specific sequence, trying first to establish communication with the vehicle using the oldest protocol. They then try the pins and protocol of newer protocol standards. Usually the code reader would be successful in its first try at establishing contact with the 4Runner using the ISO 9141-2 protocol, and there would be no problem. However these communications schemes are not foolproof and occasionally the ISO protocol attempt fails. Then the code reader tries newer protocols including CAN (controller area network). It's this CAN attempt, which toggles pin #14 (the CAN data pin) that accidentally tells the 4Runner to erase the existing zero point calibration data. Since the 4Runner (this vintage anyway) can't communicate by CAN protocol the tester re-tries the older protocols again and eventually succeeds in setting up communication by the right ISO protocol. But by then the calibration data has been erased.

The calibration, by the way, is simply a matter of telling the 4Runner VSC/TRAC computer "your yaw rate and deceleration rate are currently zero" and to save the associated values. Then the output from the sensors can be interpreted correctly.

Detail (may be helpful if you're going to do the calibration procedure yourself): The SST (special service tool #09843-18040) specified in the service manual appears to be essentially a Y-shaped test lead and is variously called a "jumper wire" or "diagnostic check wire." It's used in this case to repeatedly connect and disconnect the chassis ground (CG, pin #4) and Ts (pin #14) terminals of the OBDII connector (referred to as DLC3 in Toyota-speak). The connection/disconnection sequence and timing are described in the service manual and in several TSBs. OBDII connector diagram and pin descriptions are in TSB BR005-03.

Since the OBDII connector is at the lower edge of the dash and pointing down (right above your left foot when you're sitting in the driver's seat) it's rather tough to reach in and do the shorting to the appropriate terminals of the OBDII connector with a test lead. Especially since you're supposed to avoid moving or shaking the vehicle when you're doing this. BTW, the OBDII connector usually has a black snap-on cover over it to keep out grit, etc.

Therefore I took a couple of pieces of insulated wire about 24" long each and taped them alongside each other, and stripped both ends. To make the wire fit securely in the (female) terminals of the OBDII connector I soldered a 3/8" length of metal (cut from a heavy paper clip) to one end of each of the wires. I chose a pin size so that would fit securely in the female terminals of the OBDII connector but wouldn't distort them. I used some heat shrink tubing around the solder joint to reduce any chance of accidental shorting.

After plugging the two pins into the OBDII connector (with the other ends held apart) I was able to hold the other ends of the two wires in my hands and touch them together at the appropriate times to connect the pins of the OBDII connector. I had a helper in the passenger seat to read the instructions from the TSB to me in sequence.

This is not very hard to do, and one need only be careful. It's easier to do with the Toyota OBDII tester, of course, and would only take 5 minutes. You might be able to get your dealer to do it gratis, but you might also be charged some minimum labor hour rate.

BTW #1: Doing the sulfur TSB or others that require the replacement or reprogramming of the engine computer or the VSC computer will also require this calibration.

BTW #2: I verified that when the lights are on the VSC and traction control are indeed inoperative. ABS is working, though.

BTW #3: Shorting other pins (such as #13 Tc) at the right time can cause the appropriate dash indicators to blink in sequence to reveal trouble codes other than the OBDII ones. A generic OBDII code reader won't give you this data, and you need the service manual (physical or online) to make sense of it. I believe there is a specific code to tell you that the zero point calibration data has been lost, but I didn't look for it.

BTW #4: In the 4Runner of this vintage the OBDII connector pins populated are 4, 5, 7, 9, 13, 14, 15, 16

Elevation Will NOT go down after the elevation calibration

Unplug unit and remove motor shroud if you are savvy with a multi meter then try these trouble shooting procedure:
Perform and elevation calibration again, On the display, can you see numbers counting down and up and the treadmill is going up and down? If yes then the unit will proceed to work, if no when power is on, check on the lower board, on connector J5, do we have 5V DC between pin 1 & 3? If yes During Calibration, J5, between Pin 5 & 6, on the lower board, do we have 120V AC when treadmill is going up?
If Yes During Calibration, J5, between Pin 4 & 6, on the lower board, do we have 120V AC when treadmill is going up?
If Yes During Calibration, J5, between Pin 2 & 3, on the lower board, do we have DC voltage varying from 1.15 to 3.00? If any of the above is no then then the lower board will need replacing if all is yes then elevation motor needs replacing.

Mitsubishi Model # CS-35307 Wont turn on

The service manual is located online at this address:
Your model is eleventh from the top on the left column. Click on that link corresponding to your model number and you will find the entire service manual. It sounds like you have a problem in the "standby" power supply because the system control will be on as long as the set is plugged in. If that doesn't function then you will have the symptom you are describing.

Check for voltage at Connector KB, there should be 12VDC at pin 8 and 9VDC at pin 7. If those voltages are not there when the set is plugged in your problem lies before Connector KB if they are present then check pin 1 of IC5A01 it should be about 5.7 volts. This is the standby supply and will be on as long as the set is plugged in. There is also a possibility that the set has a failure in the Horizontal Deflection circuit and it won't let you operate the set to prevent damage to itself.

do you get a flashing led if so how many times?

this is a post from someone else:
Thought I would report my finding with this set. Maybe someone else is experiencing the same problem.

The set would turn on with no picture. No high voltage - no raster. By turning up the volume, you can hear some noise in the speakers. This set has many fuses and they all checked out ok.

I located some schematics on the net for the previous generation set - 40H80/56H80. I could not find any site with the 50H82 schematics without paying. The 40H80 seemed to match the 50H82 fairly closely. I checked the horizontal output transistor with a scope and found no signal. I traced the signal back to a board on the signal schematic called the DPC module. No HOT signal was being generated by this module. Per the schematic, I checked the voltage supply pins at this module and found everything ok except pin 6 which is supposed to be +12V. I traced this back to the power supply connector and found voltage (pin3 of 8 on BB30). Since I got the set for free and I was feeling risky, I shorted the +12V at the connector to pin 6 on the DPC. I got a small spark and the set shutoff, but I could hear static which indicated that the HOT briefly same on. I shorted out the connection again and turned the set on. This time is powered up and came back to life. I've run the set for a couple days so far and it appears to be working great.

I may have gotten very lucky, or I may be shorting out something that is not supposed to be shorted. I would really appreciate it if someone who has the real 50H82 schematic could check the connection between DPC pin 6 and the power supply connector BB30. If this is a real connection, I have to assume that the trace burned out somewhere. It vias up and down all over the place and is very hard to follow.
