Power On Self Test (POST)
Power On Self Tests run automatically each time the power [PWR] button on the Tech2
keypad is pressed on. The screen displays pass or fail results for each area tested. POST
automatically checks the following:
• MC68332 processor
• External RAM (Random Access Memory)
• Flash memory
• Display controller and display
• Sound transducer
• MC68332 RAM
• Real-time clock
• Keypad controller and keypad
• Main UART (Universal Asynchronous Receiver/Transmitter)
Results of POST may include fatal errors that do not allow you to continue, or non-fatal
errors that allow you to continue without full Tech2 operation. If normal Tech2 functions are
stopped or limited, contact Customer Support to determine if service is required.
At completion of POST, the following audible signals indicate a pass or fail condition:
• One beep - No problem. Your Tech2 is operating normally.
• No beep - Sound transducer has failed. Contact Customer Support.
• Three short beeps - Tech2 has failed POST. Contact Customer Support.
In the United States and Canada to contact the ACDelco Aftermarket Support Center, dial
1.888.212.8959.
Tech2 Self Tests
Tech2 self tests verify that the Tech2 is functioning normally. The self tests evaluate all
critical areas of the Tech2 and display pass or fail messages for each subsystem tested.
Self tests isolate user error from system hardware failures. The self tests should be
performed periodically to insure that the Tech2 is operating properly.
The Tech2 must meet the following requirements in order to do a self test:
• Screen display must be fully readable
• Keypad must be operational
Begin the Tech2 self-testing program by following these steps:
1. Press [ENTER] while viewing the Tech2 start-up screen.
2. Select F3: Tool Options from the Tech2 Main Menu.
3. Select F3: Self Test from the Tool Options menu.
