TEST DTCCHECKING FOR DIAGNOSTIC TROUBLE CODES
NOTE: The battery must be fully charged for any test in this manual.
1. Attempt to start the engine. Crank for up to 10 seconds if necessary.
2. Connect the DRB to the data link connector. Write down the trouble codes that are displayed.
3. If the DRB displays ``No Response'', go toTEST NS-2A.
4. If the DRB screen is blank or has a DRB error message, go toGeneral Information Section
3.5in this manual.
5. Iftrouble code messagesare displayed, refer to the trouble code list below and on the
following page for the appropriate test.
6. If there are no ECM trouble codes displayed, refer to one of the following:
For Immobilizer problems..................................................SK-1A
For Driveability problems.................................................NTC-1A
For No Start problems....................................................NS-1A
For Speed Control problems...............................................SC-1A
NOTE:For all component locations see General Information Section 4.0 in this manual.

** These trouble codes indicate an internal ECM fault. Using the DRB, clear ECM trouble code(s).
Perform several engine run cycles turning the ignition off for at least 10 seconds between cycles.
Using the DRB, read ECM trouble codes. If the code is present, replace the Engine Control Module.
NOTE: If trouble code TERMINAL 15 PLAUSIBILITY AFTER START-UP is present with other trouble
codes, perform TC-84 diagnosis first.
