Inspection Procedure
- CHECK HARNESS AND CONNECTOR (ECM - BATTERY)
- Disconnect the E9 or E7 ECM connector.
- Turn the ignition switch to the ON position.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
VOLTAGE SPECIFICATIONTester Connection Condition Specified Condition E9-27 (D) - Body ground(1) Clutch Pedal Depressed Below 1 V E7-21 (D) - Body ground(2) Clutch Pedal Depressed Below 1 V E9-27 (D) - Body ground(1) Clutch Pedal Released 11 to 14 V E7-21 (D) - Body ground(2) Clutch Pedal Released 11 to 14 V (1) for 1GR-FE (2) for 2TR-FE - Reconnect the ECM connector.
OK: PROCEED TO PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE
