Malfunction
NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-93).
1. Clear the DTCs with the HDS.
2. Turn the ignition switch to LOCK (0) and then back to ON (II).
3. Operate the turn signal switch in left and right positions, and wait for 6 seconds or more.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the system is OK at this
time. Check for loose or poor connections.
5. Select LIGHTING from the BODY ELECTRICAL system select menu, then enter DATA LIST.
6. Check each turn signal switch position value with the DATA LIST menu.

Turn Signal Switch (LEFT) OFF
Turn Signal Switch (RIGHT) ON
Faulty MICU; replace the under-dash fuse/
relay box (see page 22-66).
Go to step 7. 7. Disconnect the combination light switch 12P
connector.
8. Check each turn signal switch position value with the DATA LIST menu.
Data List Value
Turn Signal Switch (LEFT) ON
Turn Signal Switch (RIGHT) OFF
Data List Value

Turn Signal Switch (RIGHT) ON
Replace the combination light switch
(see page 22-166).
Go to step 9.
9. Turn the ignition switch to LOCK (0).
10. Disconnect under-dash fuse/relay box connector S (20P).
Is DTC B1280 indicated?
Are all data list values correct? Do bot h v al ues now show i ng OF F ?

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.
