DIAGNOSIS CONNECTOR AND VOLTAGE SUPPLY TEST
TECH 1 REFERS TO CHART 1 WHEN THE EQUIPMENT IS CORRECTLY CONNECTED, BUT NO DATA (WITH IGNITION ON) IS RECEIVED
FROM TECH 1.
• PERFORM TECH 1 SELF-TEST . IS TECH 1 OK?
~ ~
• IGNITION SWITCH OFF . I SEE TECH 1 OPERATOR'S MANUAL. I • DISCONNECT TCM CONNECTOR C-90 AND C-91 .
• IGNITION SWITCH ON .
• CONNECT VOLTMETER BETWEEN TERMINAL A4 AND GROUND TERMINAL C1 OR D1 OF TCM CONNECTOR.
•
THEN CONNECT VOLTMETER BETWEEN TERMINAL A7 OR AS AND GROUND TERMINAL C1 OR D1 OF TCM
CONNECTOR.
DO BOTH DISPLAYS INDICATE
BATTERY VOLTAGE?
+ ~ • IGNITON SWITCH OFF. I CHECK FUSE OR WIRE FOR OPEN. I • CONNECT OHMMETER BETWEEN TERMINAL 2 OF 3-PIN DATA LINK CONNECTOR C-9 AND TERMINAL CS OF
TCM CONNECTOR C-91.
•
THEN CONNECT OHMMETER BETWEEN TERMINAL 1 OF
2-PIN DIAGNOSTIC CONNECTOR C-92 AND TERMINAL D16 OF TCM CONNECTOR C-91
• THEN CONNECT OHMMETER BETWEEN TERMINAL 2 OF 2-PIN DIAGNOSTIC CONNECTOR C-92 AND TERMINAL C1 OR D1 OF TCM CONNECTOR C-91.
DO BOTH DISPLAYS INDICATE APPROXIMATELY 0 OHMS?
~ ~ • CHECK FOR SHORT BETWEEN TERMINAL CS AND I CHECK WIRE FOR OPEN. I GROUND AND BETWEEN TERMINAL CS AND B+. IF OK, GOTO TCM MEM-CAL REPLACEMENT.
