   1. Remove the ETCS fuse from the engine room R/B.
   2. Disconnect the A10 ECM connector.
   3. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for open)

      Tester Connection	Specified Condition
      Engine room R/B ETCS fuse terminal 2 - +BM (A10-3)	Below 1 Ω

      Standard resistance (Check for short)

      Tester Connection	Specified Condition
      Engine room R/B ETCS fuse terminal 2 or +BM (A10-3) - Body ground	10 kΩ or higher

   4. Reinstall the ETCS fuse.
   5. Reconnect the ECM connector.
2. Check the harness and connector between the ETCS fuse and positive battery cable.
   1. Remove the ETCS fuse from the engine room R/B.
   2. Disconnect the negative battery terminal.
   3. Disconnect the positive battery terminal.
   4. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for open)

      Tester Connection	Specified Condition
      Positive battery terminal - Engine room R/B ETCS fuse terminal 1	Below 1 Ω

      Standard resistance (Check for short)

      Tester Connection	Specified Condition
      Positive battery terminal or Engine room R/B ETCS fuse terminal 1 - Body ground	10 kΩ or higher

   5. Reinstall the ETCS fuse.
   6. Reconnect the positive battery terminal.
   7. Reconnect the negative battery terminal.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
