trouble shootings corvette 97

[YORK_MUSTAINE]

hola pues necesito saber cuales son los errrores comunes que tuvieron los corvette 97, como sabemos fue su primer ls1,como en el trans am el 98 consume muco aceite y etc,
pero que onda con el corvette 97?
y donde puedo ver los boletines de la general motors emitio para errores porteriores a su salida?
cuales son sus cualidades y sus desventajas de este ls1?

Las mas comunes compa:

1- Falla en el sistema Electrónico de bloqueo de la dirección. Se arregla con un relevador bypass de 35 dolares.

2.- Los engranes de las compuertas de los faros se dañan muy facilmente (Falla Identica a la del trans-am.)

3.- Las terminales a tierra se sulfatan y presentan falsos contactos.

4.- Fallas comunes en el modulo de control automatico de temperatura (El display deja de operar)

Nada que no se puede reparar, que yo sepa no presentaron fallas especiales en motor y transmisión con respecto a los siguientes C5´s.

Si necesitas más información hacerca de dichos porblemas avisame York.

Valko tiene razón, desde el 2002, pero con unos dolaritos se puede instalar facilmente en cualquier 99 a 2002 y creo que hay que cambiar el tablero para hacerlo en un 97-98.

Pues ahora si le voy a poner atención a este post con mas ganas...

De hecho ya vi en el Corvette Forum ese tema y si quiero limpiarle en la 1 chance las tierras

[valko]

estaria interesante un paso a paso como se hace eso del la limpieza de las tierras¡¡¡

para los que no sabemos por donde empezar¡¡ :D

Este es un sticky post del foro de Corvettes que me pasó Alezz y que creo que vale la pena que lo lean



IMPORTANT ELECTRICAL INFORMATION (Long!)

--------------------------------------------------------------------------------

Many of you have asked me for help on solving electrical problems and I thought this would be VERY interesting!

My 98 coupe would get the infamous "REDUCED ENGINE POWER", "TRACTION CONTROL FAILURE" and a host of random failure codes. After many, many hours of troubleshooting, replacing the BCM and TAC module, I solved most of the driveability issues. Still getting the random DTC failure codes, I thought that I may be having ground issues. Back in June I cleaned ALL of the chassis grounds and the car virtually stopped throwing the "RANDOM" DTC failure codes. Just moving the wires in the chassis ground connector was enough to change the indications and make the issues stop happening.

I had a chance to speak with some GM C5 Trouble Desk Engineers when I went to Bowling Green KY in April and they pointed out that MANY of the C5 electrical issues can be directly linked to chassis ground problems. The engineer even went as far as to recommending that I chop off the factory under hood chassis ground connectors and combine all of the wires into a single ground lug. Not wanting to just LOP off the factory connector, I took a chance and disassembled one of the ground plug connectors and to my surprise it was indeed full of corroded connections.
I strongly recommend that any C5 owner that has had or who are having electrical issues, examine and clean the chassis ground connectors. This may save you from needlessly replacing expensive electronics modules. Each ground connector can be disassembled and cleaned in about 20 min.

Just cleaning the metal ground connection between the chassis and the plug is only a band aid solution. Now that I look back, when I cleaned my chassis grounds and initially solved my issues, I believe that when the connector is being removed to clean the connection between chassis and the connector, just the wires being moved inside the plug is what changed the indications and made everything work better.
Disassembly of the chassis ground plug and cleaning the contacts inside the connector is the correct method of solving the issue!

I took some pictures of the under hood chassis ground connector and the corrosion that was in it. I cleaned the two connections on the frame rails and the left one was significantly corroded! Taking it apart and cleaning it is a very straight forward procedure and I believe that if you follow this recommendation, you will be on the way to solving the many of the electrical issues.

Here are some detailed pictures of the ground connector and the corrosion that was found inside it!

Self tapping ground screw and star washer. This is what you will need if the ground stud breaks off during removal!
