Data Link Diagnostic Test
WARNING: This page is about a different car, the 2001 Mazda B4000, 2001 Mazda B3000, 2001 Mazda B2500, and 2001 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
- Connect New Generation Star (NGS) tester to Data Link Connector (DLC), if not already connected. Turn ignition switch to RUN position. Select DATA LINK DIAGNOSTIC TEST. A test will be performed on SCP BUS (circuits 914 and 915) and ISO 9141 (circuit 70) network.
- If NGS tester displays SYSTEM PASSED, system is okay at this time.
- If NGS tester does not display SYSTEM PASSED, perform the following as applicable:
- If no response from NGS tester, see TEST 9: NO MODULE/NETWORK COMMUNICATION under SYSTEM TESTS.
- If NGS tester displays CKT 70, CKT 914 and/or CKT 915 = SOME ECUS NO RESP/NOT EQUIP, see TEST 7: NO MODULE/NETWORK COMMUNICATIONS - ISO 9141 LINK table under SYSTEM TESTS.
- If NGS tester displays CKT 914 = ALL ECUS NO RESP/NOT EQUIP, see TEST 8: NO MODULE/NETWORK COMMUNICATION - SCP LINK under SYSTEM TESTS.
- If NGS tester displays CKT 915 = ALL ECUS NO RESP/NOT EQUIP, see TEST 8: NO MODULE/NETWORK COMMUNICATION - SCP LINK under SYSTEM TESTS.
- If module in question is NO RESPONSE ON CKT 914 (BUS +) or NO RESPONSE ON CKT 915 (BUS -), repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
