Okay...i cleared all the codes then cleaned all the sensors then restarted it....same message, Service Traction System.
New codes
10-PCM P0803C
28-TCS C1295C
38 RTD C1725 H C
AO-LDCM U1064 H
A1-RDCM U1064
Thanks

I agree most don't realize how important the brake light circuit is on any car with traction control
Not only can if\t affect the TCS system but on a manual trans car it will prevent the cruise control from working and on an automatic car the cruise wil not work AND the TQ converter will not LOCK-UP

I have a 1999 frc. 6 speed manual. 54,000 miles. basically still stock
I am also getting a service abs and traction control on my dash. Traction control will not turn on at all.
Got these codes and hope it will narrow it down a little.
10-PCM NO CODES
28-TCS C1255 H C
40-BCM NO CODES
58-SDM NO CODES
60-IPC U1016 H
60-IPC U1064 H
60-IPC U1040 H
60-IPC U1088 H
80-RADIO U1064 H
BO-RFA U1096 H
BO-RFA U1064 H
BO-RFA U1016 H
NO MORE CODES
Any ideas where I should start? . Grounds, sensor jumper, sensor ect

Most likely the kiss of death for the EBCM (anti lock brake controller)
You can try a few things to see if the error is being cause by low voltage to the EBCM but it may well be the EBCM is dead.
Start by making certain the battery is fully charged. A good battery at full charge will measure 12.7 to 12.9 volts or more when measured across the battery posts with the neg battery cable disconnected. The car will start with 12.0 volts or less but the C5 electronics are not happy with 12.5 volts or less. The EBCM like other electronic sensors in the C5 go through self diagnostics and calibration at KEY ON time before the engine starts. If they fail due to low voltage the failure remains through the current ignition cycle.
Check the grounds. Here are a couple of links relative to C5 grounds:

Perform the following disgnostic to see if the ignition switch is bad:

Replace the ignition switch if the voltages measured at the points noted in the above thread are more than about 0.2 or 0.3 volts less than the measured battery voltage.
Check the condition of the connector and pins inside the connector for the EBCM as well as the wires to the EBCM connector.
If all the above proves out OK then the EBCM has gone **** up. Unfortunately there are no new EBCM available for the 97 - 2000 C5 so your only choices are a used EBCM that matches the current one or live with the problem. There is a 3rd choice but it will be an expensive one especially if you cannot do the labor yourself:
