DTC Troubleshooting
Gauge Control Module
(EEPROM) Error
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. Wait for at least 6 seconds.
4. Check for DTCs with the HDS.
Replace the gauge control module (tach)
(see page 22-277).
Intermittent failure, the system 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.
