Using the DRBIII (R)

OVERVIEW
The TCM and other components have the ability to interface over the communication bus. The DRB Scan Tool connects to a Data Link Connector located in the passenger compartment. This allows communication with the TCM.
Refer to the DRB user's guide for instructions and assistance with reading trouble codes, erasing trouble codes, and other DRB functions.

DRBIII(R) ERROR MESSAGES
Under normal operation, the DRB will display one of only two error messages:
- User-Requested WARM Boot
- User-Requested COLD Boot
If the DRB should display any other error message, record the entire display and call the MDS Hotline. This is a sample of such an error message display:

Press F4 when done noting information.

DRBIII(R) DOES NOT POWER UP (BLANK SCREEN)
If the LED's 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. A minimum of 11 volts is required to adequately power the DRB.
If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of a faulty cable or vehicle wiring. For a blank DRB screen, refer to Powertrain Management.

DISPLAY IS NOT VISIBLE





Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition.
