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. Check for DTCs with the HDS.
Go to step 4.
Intermittent failure. The gauge control
module is OK at this time. Check for loose or poor
connections. If the connections are good, check the
battery condition (see page 22-67), and the
charging system. 4. Check for DTCs with the HDS.
Faulty MICU; replace the under-dash fuse/
relay box (see page 22-66).
Replace the gauge control module (tach)
(see page 22-277).
