Help! Active Handling fault

[captharley]

I'm getting the Active Handling Inop and Service Vehicle soon read-out on the DIC. It's giving me codes 1287 and 1288. I can reset them and they go away sometimes for the rest of the trip and sometimes for only 15 or 20 minutes. From doing some research it looks like the module is bad. That costs $69 but the labor to replace it is $470. I can tell no difference in the driving or handling of the car whether it's on or off!! Can I pull a breaker and make the warnings go away??

You are not alone

I have the same issues and more for a while. I own a 97 Vette that I have had for 15 years. The 97 had modules and computer boards found only in that year. Since yours in newer you should be able to find what you need. Check out my discusion at : "Help, Abs and tcm lights stay on"

It is unlikely a 97 can have the same issues as the 01 discussed in the OP because active handing was not available in 1997.

On an 01 with JL4 "active handling" (stability enhancement system) DTC C1287 and C1288 are faults with the EBCM relating to SES. Specifically, they are faults relating to the steering wheel position sensor and its associated wiring and connections.

When these faults exist, stability enhancement is disabled. You will not detect a difference in vehicle handing with SES disabled unless you drive the car beyond its handling limits or you lose control of the vehicle on a slick surface.

As for the Service Engine light also being on–that might be related to the SES faults or it could be because a powertrain fault, also, exists.

HI there,

While yes, the steering wheel position sensor is most likely the culprit here, the labor time is due to the fact that the steering column has to be removed from the vehicle in order to change this sensor.

NOT an easy job and requires that you be very specific on your steps to remove and install the column.

Remember that this system is a SAFETY SYSTEM. You may not notice a difference now, but in an active handling event when the system is working to keep your car under control, YOU WILL NEED THIS SENSOR TO WORK CORRECTLY!

Allthebest, Paul

Here is a quote from Bill Curlee on these 2 codes:

The steering wheel position sensor at the base of your steering column isnt functioning correctly. Is your steering wheel centered/straigt when your going straight down the road??

Seeing both 1287 &1288, I would have to say, its a wiring/connector or voltage issue.

The only two components involved in this error is te EBTCM and the Steering Wheel position sensor.. Check the plug at the EBTCM and sensor.

With that said:

If you are a good DIY person you can replace it yourself. This is more on the high end of the DIY scale but it's just a car, not surgery. Here is what it requires so you can make your decision. This is something you need to fix if you ever plan to sell the car. Frankly I turn off traction control when I go out which defeats the AH feature. I like to be in control and not to have the electronics decide what needs to be done. Also eliminates the potential of unwarranted braking and lane change. While rare it does happen. Don't like the longer braking distance of ABS either but can't defeat that with a push of a button.
