Check voltage between terminals THA and E2 of engine control module connector. ON SST ECM V B 45, 65 THA E2 P (1) Connect SST (check harness "A"). (See page EG-404) SST 09990-D1000 (2) Turn ignition switch ON. C Measure voltage between terminals THA and E2 of engine control module connector.

BE4076 Wire Harness Check from the connector back side. (with harness) BE4077 Check from the connector front side (without harness) In this case, care must be taken not to bend the terminals. • Indicates the condition of the connector of ECU during the check. BR5459 Connector being checked is connected. BE5450 Connector being checked is disconnected.
