CHECK POWER SOURCE LINE VOLTAGE\n(a) Disconnect the connector 6-P.\n(b) Turn the ignition switch ON.\n(c) Using a voltmeter, connect the positive (+) probe to terminal 3 of the harness side and negative (—) probe to body ground.\nVoltage: Approx. 12 V\n(d) Connect the connector 6-P.\n\n2. CHECK POWER TRANSISTOR IN IGNITER\n(a) Disconnect the connector 4-P.\n(b) Disconnect each ignition coil from its connector.\n(c) Turn the ignition switch ON.\n(d) Using an ohmmeter, connect terminal 2 of ignition coil C and body ground.\n(e) Using a 3V dry cell battery, apply voltage to terminal 2 of connector 4-P.\nAs voltage is applied, check that there is momentary continuity.\n\n(f) Using an ohmmeter, connect terminal 2 of ignition coil A and body ground.\n(g) Using a 3V dry cell battery, apply voltage to terminal 4 of the 4-P connector.\n(h) With terminal 4 connected apply voltage to terminal 2 of connector 4-P. As you apply voltage, check that there is momentary continuity.\n\n(i) Using an ohmmeter, connect terminal 2 of ignition coil B and body ground.\n(j) Using a 3V dry cell battery, apply voltage to terminal 3 of the 4-P connector.\n(k) With terminal 3 connected apply voltage to terminal 2 of connector 4-P. As you apply voltage, check that there is momentary continuity.","image":"https://tsrm.sasquatchvc.com/images/mk3/IG/IG_015.png","url":"https://tsrm.sasquatchvc.com/mk3/tsrm/IG/15","prev":{"page":14,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/IG/14","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/14"},"next":{"page":16,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/IG/16","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/16"},"section_url":"https://tsrm.sasquatchvc.com/mk3/tsrm/IG","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/1","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/2","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/3","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/4","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/5","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/6","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/7","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/8","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/9","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/10","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/11","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/12","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/13","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/14","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/15","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/16","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/17","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/18","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/19","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/20","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/21","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/22","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/23","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/24","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/25","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/IG/26"],"note":"OCR transcript of a scanned Toyota factory manual page; verify critical values (torque specs, part numbers) against the image."}
