This code (U2108) is a communications error with the ABS module. This goes hand-in-hand with the TC and ABS lights and code P0500. The VSS is wired to the ABS first, then carries over to the ECU and speedometer. I found this out the hard way with a buddy's Catera. When the ABS module has communications errors, the speedometer loses signal from the Vehicle Speed Sensor (VSS).
 
There is hope. We called www.bba-reman.com, and they were able to fix the ABS controller. This is the black plastic box on the ABS module mounted down on the car's frame rail on the driver's side. They have DIY instructions on their website to remove the controller without removing the valve assembly and motor. This means you don't need to remove any brake lines or crack any of the lines open. Mail off the controller, and they rebuild it, test it, and warranty the work for a year, and send it back. According to them, you can still drive the car without the module. They charged us $169, which included return postage. This fixed the ABS, TC and CEL lights.
 
For the coolant light, check the coolant level in the reservoir. If it is fine, then the sensor may be bad. It is mounted to the bottom of the reservoir.

The 400 series codes means that your O2 sensor is sending a message of a bad converter or maybe the O2 sensor is bad. This could be a number of things and could be ruining your converter if not addressed.
 
The most common cause is contamination of the catalyst because the engine is burning oil or leaking coolant internally (leaky head gasket or a crack in a combustion chamber or cylinder). Converters can also be damaged if they overheat due to ignition misfiring that allows unburned fuel to pass through into the exhaust (check for a fouled spark plug or bad plug wire). The same thing can happen if the engine has a bad exhaust valve that leaks compression into the exhaust (check compression).

Code U2108 is a communications error between the ECM and ABS module.
 
How old is the Catera? How many miles? Do you ever have the brake fluid changed?

im not sure what the codes mean. but as for the coolant light you will have to replace the whole jug it runs about 40.00 at the dealer the sensor on the bottom of it is bad thats why your light is staying on.

timing tensioner kit by ironwoman

I took my 2000 Catera in to replace the timing belt, since I had heard that if it breaks it can ruin the engine. Of course, they did not have the part, so it had to be ordered. 4 days later they were suppoesed to work on the car. 5 days later they started to work on the car but discovered that they do not have the correct tool. Now today, a week later, they tell me that I need also the tensioner kit, part number 9201887, for $844.85 and tensioner pulley, part number 9196294 for $169.69. ...also a brake sensor.
 
I've read that the tensioner kit includes water pump, timing belt, and tensioner.
The dealer repair person is telling me that it is so expensive becuase they have to get the part from the dealer. They looked for aftermarket parts, but could find none.
I've looked on the internet and have seen the same part number for half that price.
 
Questions: does anyone know: is that tensioner unit really all one part...and I have to replace the whole thing like they are telling me?
   What is included in that part number 9291887?
Could damage have been done by them trying to replace the timing belt without the proper tool? (They now have the tool)
I've already paid $100 for the timing belt.
Thanks in advance for your wisdom.
