The only thing I can say is that if you pull the fuse to the ABS, it will no longer work. The light will be on in the dash, to show that the ABS is not working. The brakes will work fine but the ABS will no longer keep you wheels from skidding on a quick or hard stop. So get it repaired as soon as you can.
I hope this has been of some help

this is a common first sign of your antilock brake computer failing. You will most likely never feel a difference in your car but there is a slight chance all your safety features will not operate properly in a collision.

SOURCE: I have P0770 code on my 2003 Toyota Matrix 2WD

First I would try resetting the ECU by disconnecting the battery for a few minutes. This will remove the code. Then see if it comes back. Mind you you will not pass inspection, because the ECU will need to monitor a certain amount of driving "cycles" before inspection will accept the findings. Before that, replace your O2 sensors, and get those out of the way. P0770 is a Shift Solenoid E Malfunction. You will have to look at a manual to find out which Shift Solenoid that "E" refers to and where it is located. TC lockup, refers to the TC lockup solenoid. If so I would try replacing that and going from there. The auto transmission is a pretty complicated beast, and even the most experienced DIY'ers would go past the normal maintenance. HOWEVER, changing solenoids is considered, at least to me, DIY maintenance. Whats is your RPM when cruising at say 60 mph. If its more than 2400 rpms, then i would say it is your lockup solenoid. hope this helps

SOURCE: my 2002 toyota sienna has evap system malfunction

You are on the right track, you replaced the vent valve and replaced the vsv valve in the engine compartment that should of solved the problem as long as the correct valves were replaced, i would check for a leak in a hose for the evap system, a smoke test would be a good way, the canister may not be the problem but the valves on the canister, there are a few vsv valves on the canister and also the pressure sensor, the switching valve is very common also, there are so many valves thats why the dealer replacing the canister as an asm, hope this helps also make sure gas cap is good.

My 2001 impala has problems switching through gears while driving, only when speedometer bounces. Replaced speedo sensor, but still bunces.


You replaced the wrong part ! Should have had the vehicle checked for DTC'S - diagnostic trouble codes . Replaced what speedo sensor ? No , it's not a ground wire !
Your probably have a bad wheel speed sensor ! Have it checked for DTC'S
Speedometer
The IPC displays the vehicle speed as determined by the IPC. The IPC calculates the mileage based on the class 2 vehicle speed message from the PCM. The IPC calculates vehicle speed based on the class 2 wheel speed message from the EBCM if a loss of communication or malfunction occurs with the PCM. The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of class 2 communications with both the PCM and the EBCM.

EBCM - electronic brake control module - ABS

Why is the speedometer reading erratically?


Depending on the type an year vehicle an the electronics on the car , the instrument cluster could be at fault ! The stepper motor that moves the speedo could be the problem if a GM product ! As far as the speed sensor goes a few other things wouldn't work very well if it were bad an the check engine light would be on more then likely because this is an input to the PCM - engine computer ! The transmission would shift erratically !
Speedometer
The IPC displays the vehicle speed based on the vehicle speed signal from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit exists.
So I would say the instrument cluster is bad !

Transmission speed sensor


You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

Brake indicator lamb


My Chiltons manual for the toyota seinna 1998-2002 it says that with the lite always on means ecu malfunction and the action to take is ' ecu problem '. Sometimes these manuals leave a lot to be desired.

there appears to be a speed sensor on every wheel with the abs actuator assembly(including ecu) is attached to the brake booster.

the manual says. . . .The ABS computer(ECU) is mounted within the ABS actuator and is the ' brain' for the ABS system. The function of the computer is to accept and process information recieved from the wheel speed sensors to control the hydraulic line pressure, avoiding wheel lock up. The computer aslo constantly monitores the system, even under normal driving conditions, to find faults within the system.
If a problem develops within the system, an "ABS" light will glow on the dashboard. A diagnostic cod will also be stored in the computer and, when retrieved, will indicate problem area or component.

I hope this helps

1997 GMC Jimmy braking problem


the abs control unit controls the speedo (tach) also tells the cruise signal. abs should be fixed or replaced for any of these to work properly with the abs system not working you have no signal to the ecu to say what fuel air mix is for the speed you are doing and will think you are idling.

They are not the sensors you want. The car uses the abs wheel sensors for vehicle speed. Your problem lies in the abs system , possibly the left front sensor, abs ecu or speedo cluster, Clear the code and see if it stay out otherwise you'll need to go to a trusted technician. .

Speed-o-meter and RPM gauge do not work


if the engine is running fine and no limp mode no engine lights. abs is working then the only other thing could be the dash may need replacing as putting the battery on wrong can blow the electronics in the dash as they are both linked. i ask is there any other problems as the rev counter work to ecu in line with speedo and the abs unit to determine timing etc. speedo works of the abs system the connection between them both is the board in the dash board. you can replace the boards in the dash but you will need replacement dash parts to do this but remember if you change the dash you need to log the miles as new dash will have different miles and uk mot log your miles to dvla. USA i dont know you would need to look into this.
