8. Check for continuity between VSA modulator-
control unit 37P connector terminal No. 14 and
body ground.
Repair short to body ground in the wire
between the No. 3 (30 A) fuse in the under-hood
fuse/relay box and the VSA modulator-control
unit.
Install a new No. 3 (30 A) fuse in the under-
hood fuse/relay box, then go to step 9. 9. Reconnect the VSA modulator-control unit 37P
connector.
10. Turn the ignition switch to ON (II).
11. Clear the DTC with the HDS.
12. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
13. Check for DTCs with the HDS.
Replace the VSA modulator-control unit
(see page 19-171).
Troubleshooting is complete.

intermittent failures troubleshooting (see page
19-98).
5. Check and note BATTERY voltage in the VSA DATA LIST with the HDS.
6. Using a voltmeter, measure and note the voltage between the battery terminals.
NOTE: If the battery voltage is below 9.5 V, check
the battery (see page 22-67), and troubleshoot the
alternator regulator circuit (see page 4-28). 7. Compare the data list voltage noted in step 5 to the
battery voltage in step 6.
Intermittent failure, the system is OK at this
time. Check for loose terminals at the VSA
modulator-control unit 37P connector. Refer to
intermittent failures troubleshooting (see page
