Tech 2 reporting of history DTCs for 92-95 SIR systems (DERM & SDM) is incorrect. Use the PDT or SSS for 92-95 SIR system diagnosis. Version 45.00 will correct 92-95 SIR diagnostics with the Tech 2.
96 Saturn ABS system diagnostics for the Tech 2 are not available. Selecting 96 Saturn chassis (ABS) results in a possible wrong vehicle selected message. Use the PDT & SSS for 96 ABS system diagnosis. Version 45.00 will provide 96 chassis (ABS) diagnostics with the Tech 2.
When performing a fuel gauge test with the PDT or the Tech 2, please be aware that commanding the fuel gauge to empty (E) will not cause the Low Fuel Lamp to turn on. The fuel gauge test is designed only to test PCM control of the fuel gauge needle position.

- Oil Life Remaining
- 1st through 4th Clutch and TCC Slip Monitor
