Default Active stability control warning light

Posting for a friend

Here are the facts:



-warning lite flashes in both modes touring and sport.

-reset will temporarily eliminate lite, lite then reappears.

-I will get his code later I have a cheapy reader.

What codes should I expect?

-Any suggestions on what i might bring along in advance.

-Any guesses to what the cause will be?

thanx

Where is the message appearing? On the instrument panel or the DIC? What is the exact wording of the message (makes a difference)? Forget the code reader it will not be able to read the codes if there are any. Here is how to read codes on a C5:

Entering On-Board Diagnostics
To enter the Diagnostic Display function perform the following steps:

Turn ON the ignition switch, with the engine OFF.
Press the RESET button to acknowledge any warning messages present.
Press the OPTIONS button on the Driver Information Center (DIC) and hold.
While holding the OPTIONS button press the FUEL button 4 times within a 5 second period.
System will first enter automatic display mode followed by the manual display mode.
Automatic Display DTC Mode
The automatic display feature allows you to read each module DTC display function in an automatic display sequence. Each system module DTC will be displayed for 3 seconds followed by a 1 second pause before the next DTC is displayed in an automatic sequence. If no DTC information is available from the system currently displayed on the IPC, the IPC will display NO CODES for that system. If there is a communications problem between any system, the IPC will display NO COMM when the IPC is trying to communicate with that system. When all DTCs have been displayed for all systems, the IPC will display NO MORE CODES for 2 seconds before entering the manual mode. At any time during the automatic display function, the manual display feature can be activated by pressing any button on the DIC except the E/M button. The E/M button is used to completely exit the DIAGNOSTICS mode at any time.

Manual Display DTC Mode
The manual display feature allows you to manually select each module DTC display function. The manual mode will automatically be entered after the automatic DTC display sequence is complete, or can be entered at any time during the automatic mode by pressing any button on the DIC except the E/M (E/M button is used to exit the DIAGNOSTIC mode at any time). When the manual mode is selected, the IPC will display the MANUAL DIAGNOSTICS mode message for 2 seconds, or until any button on the DIC except the E/M is pressed. After the MANUAL DIAGNOSTICS mode message is displayed, the IPC will display the first system abbreviation and quantity of codes stored for that system, then the IPC will wait for further instructions. The buttons on the DIC provide the following functions when operating the on-board diagnostic feature in the manual mode:

DIC Button Functions

DIC Button Function

1. FUEL Previous DTC
2. GAGES Next DTC
3. TRIP Previous System
4. OPTIONS Next System
5. E/M Exit Diagnostics
RESET Clear DTCs

Active handling is a function of the ABS system and not of the Real Time Damping System so the Sport and Touring settings shouldn't usually set an Active Handling message unless the RTD system is causing a problem with the PCM.

The message must be on the DIC as that is the only place that Service messages can be displayed. The instrument panel has a warning light. There is no message like the one you describe. Here is a list of potential messages related to the stability system or ride control system that can be displayed on the DIC:

ABS ACTIVE
ACT HNDLG-WARMING UP
ACTIVE HANDLING
COMPETITIVE DRIVING
MAXIMUM SPEED 129 KM/H (80 MPH)
REDUCED ENGINE POWER
SERVICE ABS
SERVICE ACTIVE HNDLG
SERVICE RIDE CONTROL
SERVICE TRACTION SYSTEM
SERVICE VEHICLE SOON
SHOCKS INOPERATIVE
TRAC/ACT HNDLG-ON/OFF
TRACTION SYS ACTIVE
WARM UP COMPLETE

As you can see there is no Active Stability message. Do you mean Active Handling? Which message or combination of messages is showing on the DIC? As I said before it makes a difference.
