Fault code help - TCS

TCS
C1287 - steering sensor rate malfunction
C1288 - dont have a description for this one.

The DIC display reads something like service active handling soon (I will have to look at it next time out ) I can reset this but it will come on again. The little traction off symbol on the dash never goes out anymore.

This first happened about a week ago while driving under acceleration in a straight line.

What to look for and where to start or is this just something that can be cleared.

2001 C5 automatic - 36,000 miles

Cheers





Two other faults I recorded are LDCM 2272 and RDCM 2265 - not really to concerned about these ones right now, they will be for another day.

Hi there,

Unfortuntely, you will most likely need a steering wheel position sensor and then have the ABS module reprogrammed.

NOT a fun job.

The steering column has to be removed from the vehicle to change that sensor.

Hello Paul

1.What would of caused this sensor to fail?
2.Is there a test to ensure that it is the sensor?
3.How is this sensor tied in with the TCS?
4.What would you do?

Cheers

Looking for further information. I also added some new details that may help pinpoint the problem.

1.What would of caused this sensor to fail?
2.Is there a test to ensure that it is the sensor?
3.How is this sensor tied in with the TCS?
4.What would you do?

Today I took it to the end of the street at regular speeds with no issue until I braked for the stop sign. At that time it seemed that the left front brake pulsated as through it was trying stop on a slippery surface. At that time the active handing showed up on the DIC.

This car has the orig. brakes.

I am still wondering why this has anything to do with the steering.

Where can I begin.

Also how do you completely clear the faults using the DIC.

Cheers

HI there,

The system uses the steering wheel position sensor to accurately determine the direction you WANT to go when an active handling event occurs.

In order for the active handling system to work, you need to have a correct input (SWPS) vs the actual direction of the vehicle(yaw rate).

So, it compares the 2 signals and then checks to see if it needs to make corrections.

So, that being said, the steering sensor is a soft spot for all GM, as Cadillac uses the same sensor.

When you do the scan of the 28-TCS, simply push and HOLD the reset button until the codes clear.

This seems to be exactly what is happening with my 01 - what do they do to fix it. Is there a history with the 01's as well.

Active handling system” may misapply the brakes.
by Ken Zino on May.03, 2010
The computer can cause the car to veer suddenly.

General Motors Company is recalling more that 40,000 Corvette models that were made between March 2004 and January 2006 and equipped with a tilt and telescoping steering column.
Movement of the steering column can damage a Delphi supplied wiring connector for the steering wheel position sensor and cause an open or intermittent circuit. If this happens, the message, “Service Active Handling System” will appear in the driver information center, and a computer could apply one or more of the brakes causing the sports car to veer left or right.
The National Highway Traffic Safety Administration had received more than 2,000 complaints about the problem, but GM maintains that very few of the complaints involved brake application.
GM says that there are no reports of injuries.
GM is now in the process of notifying owners of the safety recall. Dealers are required by law to repair the vehicles free of charge. Owners may contact Chevrolet at 1-800-630-2438 or at the Owner Center at www.gmownercenter.com.
GM’s recall campaign number is N100118. Owners may also contact the National Highway Traffic Safety Administration’s Vehicle Safety Hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to http://www.safercar.gov. NHTSA Campaign ID Number: 10V172000. NHTSA Action Number: EA09002.

H ithere,

This is a completely different system and cause of the problem.

You need a sensor, its that simple.

Ok, I will look into getting the sensor changed. Does not really seem to be that bad of a job. Looks like about 2 to 3 hours from what I have read and the cost of the part. I will have to see if my dealer sees it the same way as me.

Paul - Thank you again.

Cheers

Paul, just a question along these lines: I get "service active handling" and an ABS fault simultaeously on occassion. I usually get it to go away by shutting it down and restarting, but is this the same problem? I usually drive with active handling turned off. Are there other problems I'm going to experience besides the active handling not working?

FYI - I called the dealer yesterday about having this sensor replaced as suggested by Paul. I experience the same issue that you just mentioned. The Corvette tech recommended that I first remove the connector to the sensor and check for corrosion at the terminals. From what he said there needs to be 5 volts present at the sensor and because our cars sit so much this may be causing the problem.
