You need to have a scan tool hooked up to read DTC'S diagnostic trouble codes ! These would be hard faults .
DTC 6 Theft Deterrent Relay Control Circuit Shorted
DTC B2734 Coded Key Controller Memory Failure
DTC B2960 Invalid Coded Key Present
DTC B3031 Key Decoder Device in Assem Learn Mode
DTC B3055 Key Not Present.
Do you have another key you can try .
When learning the pre-release password, as well as the challenge and response sequence, the engine control module (ECM) is placed in learn mode. DTC P0633 will set automatically as an indicator that the system is in learn mode and not as a fault indicator. Once the password and challenge/response are learned, learn mode will be exited when the engine is successfully started. At this point, the DTC will be cleared. If the ECM does not exit learn mode, P0633 will remain current and indicate a fault.
The "key" referenced in the DTC descriptor does not refer to the vehicle key. In this case, "key" is referring to the challenge response.
DTC P0633 requires a successful engine start to exit the learn procedure and clear the DTC. If an unrelated malfunction exists that causes engine starting to be disabled or otherwise unavailable, learn mode will not exit and DTC P0633 will remain current. In this situation, the cause of the inoperative engine starting must be corrected before diagnosing DTC P0633. DTC P1629: Theft Deterrent Fuel Enable Signal Not Received
The theft deterrent module (TDM) sends the pre-release password to the engine control module (ECM) via the serial data circuit. The ECM then sends a challenge to the TDM. Both the ECM and TDM perform a calculation on this challenge. If the calculated response from the TDM equals the calculation performed by the ECM, the ECM will allow vehicle starting.
DTC P1629 is an indicator that the challenge response was not received within the required 2 second window. This does not necessarily indicate a fault is present with the TDM or ECM. Factors such as a long engine crank, a delay in the serial data communication, or B-codes set in the TDM will cause DTC P1629 to set. This DTC should not be used as a fault indicator, but rather as a symptom to assist in the diagnosis of these other systems.
Who checked the codes , you -dealer ? You need to have BCM checked for codes B - codes ! you need a up scale diagnostic scan tool for that , dealer Tech -2 ! DTC B3935 57 : Transponder Authentication Error DTC B3976 46 : Unconfigured Transponder/Vehicle Configuration Not Programmed DTC B3060 : Unprogrammed Transponder Identification Code Received DTC B3055: No Transponder Modulation or No Transponder DTC B3031: Security System Controller In Learn Mode
Whenever the ABS module turns on the ABS light in the dash it is to alert you to the fact that a fault has occurred in the ABS system and the control module has turned off the ABS brake control, you now have regular non ABS brakes. The waring light will stay on until the fault is corrected. Since a large number of problems would cause this you must get the control module scanned to retrieve the fault code that was set in the control modules memory when it turned on the light. Once the fault code is known the process of diagnosis and repair can begin.
The fault is generally due to a problem in the Vehicle Speed & Idle Control area
Fault Description: Battery power supply voltage malfunction Note: This DTC can be flagged due to fuel injection pressure sensor fault. If P0193 is also flagged, correct first.
Action of ECM:- none
After clearing the DTC, complete the Engine temperature cool (cooling fans not running) Remove ignition key for 20 seconds (cooling fans not running) Ignition key in, position II for 5 seconds (do not start) Repeat cycle two additional times Check for a reoccurrence of fault DTC.
Possible Fault:- ECM battery power supply open circuit, high resistance
P0146 pd means pending code
Pending codes and DTCs?
Posted on November 12, 2010 by fcrmaster
When reading codes from your vehicle the fault code reader may show them as pending codes or normal Diagnostic Trouble Codes (DTC).
Pending codes (also known as continuous monitor codes) will be registered when an intermittent fault occurs. If that fault does not happen again after x number of start/stop cycles, the ECU will erase the code from memory. If the fault is persistent it becomes a DTC.
If you have read pending codes it is advisable to check the codes again after a week or so. If there is no apparent problem with the vehicle it is safe to erase the codes too and check back. But always make a note of any fault codes with the date and mileage of a vehicle.
If the codes read include a DTC then you need to investigate further. This you can either do yourself or advise your garage. If, again, you don't see an apparent problem (depending n the severity of the code) with the vehicle you can note the codes down and erase them. Then check again after a week or a few days depending on how often the vehicle gets used. If a repair has been made (previous owner) the DTC may just not have been reset after the repair.
The other numbers behind the code 01/06 ,

These don't mean anything . cheap code reader .

Sorry but this is something you should take to a qualified repair shop that has a diagnostic tool that can view sensor scan data. Causes of lean condition trouble codes P0171 P0174 GM 5 3L
The code U1262 point out a communication fault between the vehicle modules and a scanner. It may be best to visit your local dealer to find if one of the vehicles control modules has failed. In some cases this can be as simple as a blown fuse, but there is always a reason for a fuse to blow
and a oil sending circuit fail. would need to be tested.
P1000 DTC code is a manufacturer specific trouble code. your code reader is not reading or communicating correctly you will need to check the fuses for all the modules and check the connections on the plugs and the units to check the modules to see if they have good contact. also check the main earth from the battery to the shell and make sure the contact is good.

Displaying & Reading Trouble Codes (DTC Memory) Air Conditioning (A/C)
Models 208 as of MY 1998
Diagnostic trouble Code Memory 
The A/C pushbutton control module (N22) has DTC memory and data output. The diagnostic trouble codes and data are displayed via the temperature display window. The stored DTC's will remain in memory even with the vehicle battery disconnected.
The DTC memory differentiates between current and intermittent faults.
Numerous DTC's can also be read with the Hand-Held Tester (HHT).
Preparations for DTC Readout
Review 11, 12, 13, 14, 15, 21, 22, 31, 31, 41
Temperature selector: left: "HI"; right: "LO"
Within 20 seconds press REST and EC simultaneously for more than 5 seconds.
The LED in Recirculated Air flashes and the display shows "d1A".
Press AUTO repeatedly until all DTC's are displayed. Record each DTC as it is displayed.
Each fault (short circuit, open circuit) is assigned a DTC. Thus in the left display: "E1" appears, and the right display indicates the DTC. The current faults (refer to table) are displayed first, next, the intermittant failures (e.g. 45 °5) are displayed in the display window next to the FAN symbol. By pressing the right AUTO the next DTC is displayed.
To erase: Can only be performed after all faults have been readout. Press left AUTO and right AUTO buttons simultaneously for more than 2 seconds and the display shows: left: "d" and right: "FF". To cancel erase: By pressing the left AUTO button, the current faults will appear again.
Select a base temperature setting.
Turn ignition OFF, to end test.
Due to instrument cluster (IC) series interface, DTC's may be stored in IC memory, therefore readout and erase DTC's from IC memory.
