Reset the abs and traction contols system on my '05 hyandia elant
After having a flat tire my abs and tcs light indiacators are on indicating that I have no abs and tcs. the owners manuel says nothing about resetting these features

Is your trac light lit ? If so it has a problem an till it is fixed , you can't reset it. Need to have it checked for DTC'S - diagnostic trouble codes .
If the ABS control module detects a malfunction, it will disable TCS and will command the BCM to turn the TRAC LED Off. The driver can also disable TCS, if desired, by depressing the TRAC switch. When the driver depresses the TRAC switch, the ABS control module will disable TCS and will command the BCM to turn the TRAC LED Off.
DTC C0276 TCM Traction Control Not Allowed
DTC C0275 or C0276
The TCM sends a serial data message to the electronic brake control module (EBCM) indicating that torque reduction is temporarily not allowed.
DTC C0550
DTC C0896
The electronic brake control module (EBCM) is required to operate within a specified range of voltage to function properly. During antilock brake system (ABS) and traction control system (TCS) operation, there are current requirements that will cause the voltage to drop. Because of this, voltage is monitored out of ABS/TCS control to indicate a good charging system condition, and also during ABS/TCS control when voltage may drop significantly. The EBCM also monitors for high voltage conditions which could damage the EBCM.
PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through
the operators guide shows what these mean and what to do.

it resets each drive. the opr guide says that, and does.
its a very complex system, you should RTM.
ill quote your missing pages.
ABS: If the light remains on after start-up or comes on and
stays on at road speeds, it may indicate that the ABS has
detected a malfunction or has become inoperative. The
system reverts to standard non-anti-lock brakes. ESP:/TCS The ESP/TCS Indicator Light (located in the instrument
cluster), starts to flash as soon as the tires lose traction
and the ESP system becomes active. The ESP/TCS Indicator
Light also flashes when TCS is active. If the
ESP/TCS Indicator Light begins to flash during acceleration,
ease up on the accelerator and apply as little throttle
as possible. Be sure to adapt your speed and driving to
the prevailing road conditions
is this clear? if not ask more, questions , more specific and we can peel the onion deep as you want.

Whenever this warning light or any
other stays on in the dash it is indicating that the systems control
module (or the system sensor in the case of lights like low oil
pressure, door open indicators etc.) has detected a fault, it then
disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL,
CEL and BCM faults and others) as long as the light is on. You must
now have the dealer hook up a special electronic diagnostic tool and
"scan" the system for the fault code that is stored for the
problem(s)
