1. Attempt to start the engine. Crank for up to 10 seconds if necessary.
2. Connect the DRB to the engine diagnostic connector. Write down the trouble codes that are displayed.
3. If the DRB screen displays "No Response", go to TEST NS-6A.
4. If the DRB screen is blank or has a DRB message refer to Testing and Inspection.
5. If trouble code messages are displayed, refer to the trouble code list for the appropriate test.
6. If there are no trouble codes displayed, refer to one of the following:

- For Driveability problems NTC-1A
- For No Start problems NS-1A

NOTE: The decimal test numbers for these trouble codes were derived from the hexadecimal codes as set in the PCM. Therefore, some test numbers will be missing because all codes are not applicable to all vehicles.

* These DTC's can be set by Low Fuel Level, add fuel to 1/4 tank and test for DTC to set again.
** For an ENGINE IS COLD TOO LONG trouble code, the engine does not warm to 176°F while driving for 20 minutes after start up (check thermostat).

For an INTERNAL CONTROLLER FAILURE trouble code, replace the powertrain control module and go to Verification TEST VER-2A.
For a PCM FAILURE SPI COMMUNICATIONS trouble code, replace the powertrain control module and go to Verification TEST VER-2A. Verification Test VER-2A - Road Test Verification
