USING THE DRBIII

Refer to the DRBIII user's guide for instructions and assistance with reading diagnostic trouble codes, erasing diagnostic trouble codes and other DRBIII functions.

DRBIII ERROR MESSAGES





Under normal operation, the DRBIII will display one of only two error messages:
- User-Requested WARM Boot or User-Requested COLD Boot.

If the DRBIII should display any other error message, record the entire display and call the STAR Center for information and assistance. This is a sample of such an error message display:

DRBIII DOES NOT POWER UP (BLANK SCREEN)

If the LEDs do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link 16-way connector cavity 16). A minimum of 11 volts is required to adequately power the DRBIII Also check for a good ground at DLC.

If all connections are proper between the DRBIII and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRBIII may be the result or a faulty cable or vehicle wiring.
