Code & Message To Test Conversion (Part 4 Of 4):

NOTE: The battery must be fully charged for all tests in this section.

1. Attempt to start the engine. Crank for up to 10 seconds if necessary.
2. Connect the DRB to the engine [1][2]diagnostic connector. Write down the trouble codes that are displayed.
3. If the DRB screen displays "No Response", go to TEST NS-SEL. NS-SEL No Start Selection Menu
4. If the DRB screen is blank or has a DRB error message check these:

DRB or scan tool Does Not Power Up
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 (data link connector cavity 16). 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 faulty cable or vehicle wiring. For a blank screen, refer to the appropriate body control module diagnostics.

Display is Not Visible
Low temperatures will affect the visibility of some displays. Adjust the contrast to compensate for this condition.

5. If trouble code messages are displayed, refer to the trouble code list in the images for the appropriate test.
6. If there are no trouble codes displayed, refer to one of the following:
- For Driveability problems NTC-1A NTC-1A No Trouble Code Menu - Start Here

- For No Start problems NS-SEL NS-SEL No Start Selection Menu

- For Speed Control problems SC-1A SC-1A Checking Speed Control Operation

- For Charging problems CH-1A Charging System (CH) Tests

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