Retrieving DTCS
Diagnostic Trouble Code (DTC) is retrieved using Tech 2 scan tool. Follow scan tool manufacturer's instructions to perform tests.
Before diagnosing DTC(s), perform DIAGNOSTIC SYSTEM CHECK first. Scan tool is also used to perform test modes for diagnosis and service of the ABS/TCS system. See SCAN TOOL TEST MODES .
