Is there continuity?
YES -
Go to Step 38 .
NO -
Repair open in the wire between the under-hood fuse/relay box and ECM connector No. 2 terminal No. 43, then go to Step 33 .
  1. Turn the ignition switch OFF, and wait 2 minutes.
  1. Check for continuity between body ground and intake shutter valve 10P connector terminals No. 4 and No. 9 individually.
Is there continuity?
YES -
Go to Step 23 .
NO -
Repair open in the wire between the intake shutter valve and G101, then go to Step 33 .
  1. Disconnect ECM connector No. 1 (96P).
  1. Connect between intake shutter valve 10P connector terminals No. 1 * , No. 6 to body ground with a jumper wire individually.
  1. Check for continuity between ECM connector No. 1 terminals No. 71 * , No. 95 and body ground individually.
Is there continuity?
YES -
Go to Step 26 .
NO -
Repair open in the wire between the intake shutter valve and ECM connector No. 1 terminal No. 71 * (No. 95), then go to Step 33 .
  1. Reconnect ECM connector No. 1 (96P).
  1. Turn the ignition switch ON (II).
  1. Clear the DTC with the HDS.
  1. Start the engine.
  1. Check for Temporary DTCs or DTCs with the HDS.
