Need Help ...Have Codes
Have a 2001 vert M6 with 46,000 miles and I'm getting the "Service Active Handling" warning about every other ignition cycle. I've pulled the codes and read as much as I could but I'm not sure where to start.
Codes;
c1288h
B2860H
U1064H
U1000H
Any direction would be appreciated. Thanks in advance
Jake

C1288 is the relevant code but its history (H)
Clear it down and see if it comes back. If so we can follow up. The U codes are battery related. make sure your battery is fully charged as this can affect things. You could clean the grounds at the wheel hubs for a starter. It may be a problem with the steering wheel position sensor but dont worry at this stage.

Clear your codes since those are all old also. H=history C=current search "trussme" write up on the abs/active handling issue. Everything you need and want to know is in their to fix it.

clear all the codes if you dont know how just ask and i will tell you as you can see the H means history codes try to claer the to see if any come back

Probably more than you wanted to read......
DTC C1287 or C1288
Circuit Description
The vehicle stability enhancement system (VSES) is activated by the electronic brake control mdoule (EBCM) calculating the desired yaw rate and comparing it to the actual yaw rate input. The desired yaw rate is calculated from measured steering wheel position, vehicle speed, and lateral acceleration. The difference between the desired yaw rate and actual yaw rate is the yaw rate error, which is a measurement of oversteer or understeer. If the yaw rate error becomes too large, the EBCM will attempt to correct the vehicle's yaw motion by applying differential braking to the left or right front wheel.
The amount of differential braking applied to the left or right front wheel is based on both the yaw rate error and side slip rate error. The side slip rate error is a function of the lateral acceleration minus the product of the yaw rate and vehicle speed. The yaw rate error and side slip rate error are combined to produce the total delta velocity error. When the delta velocity error becomes too large and the VSES system activates, the drivers steering inputs combined with the differential braking will attempt to bring the delta velocity error toward zero.
The VSES activations generally occur during aggressive driving, in the turns or bumpy roads without much use of the accelerator pedal. When braking during VSES activation, the brake pedal will feel different than the ABS pedal pulsation. The brake pedal pulsates at a higher frequency during VSES activation.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
C1287
One of the following conditions exists:
• The steering wheel position sensor is synchronized and the steer rate (speed that the steering wheel appears to be turning) is greater than 1100 degrees/second.
• The steer rate is less than 80 degrees/second and the difference in the phase angle between Phase A and Phase B is greater than 20 degrees.
• The 2 steering sensor signals (Phase A and Phase B) do not agree for 1 second. Under this condition, this DTC will set along with DTC C1281.
C1288
One of the following conditions exists:
• Both Phase A and Phase B are greater than 4.9 volts for 1.6 seconds.
• Both Phase A and Phase B are less than 0.2 volts for 1.6 seconds.
• The difference in the changes in Phase A and Phase B is greater than 35.2 degrees for 9.76 milliseconds.
Action Taken When the DTC Sets
• The EBCM disables the VSES for the duration of the ignition cycle.
• The Traction Control and Active Handling indicator turns ON.
• The DIC displays the Service Active Handling message.
• The ABS remains functional.
Conditions for Clearing the DTC
• The condition for the DTC is no longer present and the DTC is cleared with a scan tool.
• The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
Diagnostic Aids
• The scan tool may display 2 additional characters after the DTC. Take note of the 2 character code and any other DTCs that are set. The 2 character code is an engineering aid used in order to determine the specific criteria which caused the DTC to set.
• During diagnosis, park the vehicle on a level surface.
• Check the vehicle for proper alignment. The car should not pull in either direction while driving straight on a level surface.
• Find out from the driver under what conditions the DTC was set (when the DIC displayed the Service Active Handling message). This information will help to duplicate the failure.
• The Snapshot function on the scan tool can help find an intermittent DTC.
Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. Perform the Steering Position Sensor Test in order to verify if the steering wheel position sensor (SWPS) is operating properly.
3. Tests for the proper operation of the steering wheel position signal A circuit in the low voltage range.

5. Tests for the proper operation of the steering wheel position signal A circuit in the high voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to ground.
6. Tests for the proper operation of the steering wheel position signal B circuit in the high voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to ground.
7. Tests for a short to voltage in the 5 volt reference circuit.

B2860 Telescoping Column Position Sensor Failure
Ck all of the connectors coming out of the steering column. Also try running the Steering Wheel full range in and out several times...Might clean off the sensor.
This list shows all your codes... Good luck

Has your steering rack been disconnected resently????

Ck Battery Voltage, Ground and Data Buss to the BCM..
If you do not have the schematics shoot me a PM and I'll send them to you....
I'd work on the C1288 first......

I wouldn't worry about the U codes if everything else is working OK. Focus on the steering sensor and the Telescopic steering wheel sensor issues. Many people are driving around in C5s with U Codes and there is nothing wrong with the car.
The modules on the serial data bus constantly send State of Health messages to each other. If a module doesn't respond to one of those messages a U Code is set. These messages can be intermittently blocked by electrical noise on the serial buss or other issues. When the module fails to respond to just one SOH message the U code is set. Most modules respond to the next message but the U Code isn't reset so it shows up on the DIC or a scanner. If you get multiple U codes in several different modules then you should look at battery connections and grounds as a bunch of U codes probably indicates a voltage level problem. From the Service Manual:
"Communication DTCs do not necessarily indicate a malfunction. These DTCs are only intended to aid in diagnosing an intermittent communication malfunction that is accompanied by a symptom. If the vehicle does not experience a symptom related to a communication malfunction, these DTCs can be disregarded."

I have the B2860 HC code as well. The telescopic steering hasn't worked since I bought the car a month ago, but it never threw a code until yesterday. I don't know where to start on troubleshooting the telescopic steering. I already tried the Push-pull on the wheel while operating the switch and got nothing. The check engine light is scaring my wife, so even if I don't get the telescopic working, I need the code cleared permanently!
