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 using the HDS.
2. Turn the ignition switch to LOCK (0), and then back to ON (II).
3. Start and run the engine for at least 5 seconds then turn the engine off.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the F-CAN
communication line 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.
5. Check for DTCs in the ECM/PCM or ABS/VSA.
Troubleshoot the ECM/PCM or ABS/VSA.
Go to step 6. 6. Do the Gauge Control Module (Tach) Input Test
(see page 22-271).
Go to step 7.
Repair the faulty input then recheck for
DTCs.
7. Substitute a known-good gauge control module (tach).
8. Clear the DTCs with the HDS.
9. Turn the ignition switch to LOCK (0), and then back to ON (II).
10. Start and run the engine for at least 5 seconds then turn the engine off.
11. Check for DTCs with the HDS.
Substitute a known-good ECM/PCM and
retest. If the system/indication goes away, replace
the original ECM/PCM.
The original gauge control module (tach) is
faulty; replace the gauge control module (tach)
(see page 22-277).
