Господа, а вышеперечисленные шаманские истории про сброс системы на блейзере распространяются на Таху квадрат 1997 г.в. Спасибо, что такая тема есть и есть мудрые шаманы, а то пришлось бы к тупеньким официалам обращаться, денежку тратить неизвестно за что.
цитируем оллдату

Transfer Case: Reading and Clearing Diagnostic Trouble Codes
Clearing Diagnostic Trouble Codes - NV 243 (Electric Shift)
- Perform the following to clear the diagnostic trouble codes (DTC) and stored memory from the transfer case control module (TCCM).
1. Turn the ignition switch to the "OFF" position.
2. Remove the 20-amp T-case fuse (Number 2).
3. Wait at least 40 seconds then replace the fuse.
4. Cycle the ignition switch from "RUN" to "OFF" five times to clear diagnostic trouble code 1 from the TCCM.
Important:
- The codes will not clear if the 20-amp T-case fuse is not removed for at least 30 seconds.
- Code 1 will continue to occur until the ignition switch is cycled from "RUN" to "OFF" five times.

Transfer Case: Reading and Clearing Diagnostic Trouble Codes
Reading Diagnostic Trouble Codes - NV 243 (Electric Shift)
The diagnostic trouble codes are displayed on the three transfer case shift select buttons. The Shift select buttons are located on the instrument
panel. When connector pin 13 on the data link cable is grounded, and the ignition switch has been off for at least five seconds prior to positioning
the ignition switch to run, the shift select buttons will blink various times together to indicate diagnostic trouble codes from 1 to 4.
1. Position the ignition switch to "OFF".
- Ensure the ignition switch is positioned to "OFF" for at least 6 seconds.
2. Connect pin 13 on the data link cable to a vehicle ground source.
- The data link connector is located in the cab under the instrument panel on the drivers side.
- Look for an unplugged cable lead with a connector that is housed by the bottom of the instrument panel trim.
3. Position the ignition switch to "RUN".
4. Note the shift select buttons for blinking codes. Refer to DIAGNOSTIC TROUBLE CODES.
If the shift select buttons all blink one time and stop, and do not continue blinking, no fault codes are stored in the TCCM.
The transfer case shift select buttons will blink to identify any stored DTC. If only one code is stored in the TCCM memory, that code will blind
repeatedly with a three second delay between blinking sequences. If more than one code is stored, the first code will blink once, then after a three
second delay, the next code will blink. This sequence will continue until pin 13 is no longer grounded.
When reading the diagnostic trouble codes, the number of shift select buttons blinking will indicate the code number.
