Question about Toyota ECHO

1 Answer

Does the 1999 Echo have a body control module? Are the BCMs and ECUs the same unit or two separate units?

I have lost the key to my October 1999 Echo and so I need to replace the key, computer, ignition barrel and drivers door lock. The other option was for Toyota to replace the key at a cost of around $900.

- Connect the pins 4 (CG) and 13 (TC) with a paper clip or automotive wire, keep open the driver's door and leave the ignition switch ON for 30 minutes.
- After 30 minutes, switch OFF the ignition, remove the jumper wire and start the engine.

There's a TSB on that problem. It involves broken wires in the A and B pillar from the central convenience module to the rest of the car. Ask your VW dealership or what not for a more specific answer.

You can save a LOT of money by fixing it yourself.

All that is wrong with the knob are broken wires from the knob's PC board to the main PC board on the AC control.

All you have to do is remove the AC main control, take it apart, and resolder the broken wires from the PC board with the knob on it, to the main AC pc board. There are 3 wires, any number could be broken.

If you take it apart and solder the broken wires, this WILL fix your issue. Just make sure you put the wires back exactly where they go.

A FIXYA rating (4 blue diamonds) would be most appreciated for my assistance.

SOURCE: Drivers side door lock barrel fell out???

This is a common fault on A4 VAG cars (Mk 4 Golfs, Skoda Octavias, Seat Leon, Beetle, Audi TT , Audi A3) you will need to remove the door card from the inside. Repair kits are available so it may be possible to repair the lock barrel but for the effort htat is required to remove the door card I would replace the lock barrel rather than repair it.

1999 chrysler seabring coupe has fire to the coil not the cap or roter 2.5 v6

Check the ECM and BCM. (Engine Control Module / Body Control Module.) Sounds like the Chrysler Anti Theft and BCM are not talking to the ECM reliably. Check connections and the wiring harness first to these components. If no change, try Dealer testing of both units. This could be expensive as only the dealer and a few module 'rebuilders' have computer codes and program to isolate the problem(s).

What does the body control module control

A body control module is a computer component in an automobile that checks, regulates and operates electronic devices throughout the car. There was a module for the air-conditioning, a module for the interior lighting, a module for the door locks, and so forth. A body control module gathers all these separate modules under one system so that they function together instead of separately, to make diagnosis easier for the mechanic and dealership a mechanic often is pointed to the right area by the body control module system, which sends out a code that shows what module is not responding. At times, good-day !

Driverside window will not roll down

After testing for power and ground at the motor and switch I'd have a look at the BCM (body control module) or window module if it is separate. The BCMs of that generation are under the back seats and can easily get fluid spilled on them or just short out on their own.

I need to locate the fuse for my gas gauge in my 99 malibu

There is no fuse specific to the fuel gauge. The Instrument panel has two fuses that supply power to everything it has on it. The fuel gauge signal is received from the body control module which sends out a signal voltage to the fuel level sending unit. Depending on where the float in the tank in determines how much resistance the sending unit has. the body control module interprets the voltage value into a fuel level and sends a signal to the gauge.

If the gauge is not working the most common cause is the sending unit in the tank.

An engine control unit (ECU) is an electronic control unit which controls various aspects of an internal combustion engine's operation. The simplest ECUs control only the quantity of fuel injected into each cylinder each engine cycle. More advanced ECUs found on most modern cars also control the ignition timing, variable valve timing (VVT), the level of boost maintained by the turbocharger (in turbocharged cars), and other peripherals.
ECUs determine the quantity of fuel, ignition timing and other parameters by monitoring the engine through sensors. These can include, MAP sensor, throttle position sensor, air temperature sensor, oxygen sensor and many others. Often this monitoring and control is done using a control loop (such as a PID controller).
Before ECUs, most engine parameters were fixed. The quantity of fuel per cylinder per engine cycle was determined by a carburetor or injector pump.
