terminals pushed back in the connector. Repair the wiring STEP 4. Check ETACS-ECU connectors C-307 and C-309 for Q:Is ETACS-ECU connectors C-307 and C-309 in good condition? YES: Go to Step 5. NO: Repair or replace the damaged component(s). Refer to GROUP 00E, Harness Connector Inspection P.00E-2. STEP 5. Check the battery power supply circuit to the (1) Disconnect ETACS-ECU connectors C-307 and C-309 ZC6022230002 Connector C-307 (2) Measure the voltage between ETACS-ECU connector C-307 ⦆ The voltage should measure approximately 12 volts ZC6022230003 Connector C-309 (3) Measure the voltage between ETACS-ECU connector C-309 ⦆ The voltage should measure approximately 12 volts Q:Is the measured voltage approximately 12 volts (battery positive voltage)? YES: Go to Step 7. NO: Go to Step 6. STEP 6. Check the wiring harness between ETACS-ECU Q:Is the wiring harness between ETACS-ECU connector C-306 (terminal 1 or 2) and the fusible link (34) or (36) in good condition? YES: No action is necessary and testing is complete. NO: The wiring harness may be damaged or the connector (s) may have loose, corroded or damaged terminals, or ETACS 54Ad-59 DIAGNOSIS |
