1. Before troubleshooting the turn signal/hazard warning lights system, troubleshoot the system using B-CAN
System Diagnosis Test Mode A (see page 22-93).
2. Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box. If the fuse is blown, replace it and go to step 3.
3. Disconnect under-dash fuse/relay box connectors E, F, G, M, P, Q, R, S, and T. NOTE: All connector views are shown from wire side of female terminals.

6. Reconnect connectors to the under-dash fuse/relay box, and do these input tests at the following connectors.
 If any test indicates a problem, find and correct the cause, then recheck the system.
 If all the input tests prove OK, the MICU must be faulty; replace the under-dash fuse/relay box.
