1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn it to
ON (II) again.
4. Check for DTCs with the HDS.
If DTC 61-01, 61-21, 61-22, 61-23, and/or
62-21 is indicated at the same time, check the
battery performance (see page 22-67), and do the
alternator and regulator circuit troubleshooting first
(see page 4-28). If DTC 61-01, 61-21, 61-22, 61-23,
and/or 62-21 is not indicated at the same time,
replace the yaw rate-lateral acceleration sensor
(see page 19-169).
Intermittent failure, the system is OK at this
time. 1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn it to
ON (II) again.
4. Wait 60 seconds or more.
5. Check for DTCs with the HDS.
Replace the yaw rate-lateral acceleration
sensor (see page 19-169).
Intermittent failure, the system is OK at this
time.

VSA MODULATOR-CONTROL UNIT 37P CONNECTOR
14. Disconnect the VSA modulator-control unit 37P
connector (see step 2 on page 19- 171).
15. Measure the voltage between VSA modulator- control unit 37P connector terminal No. 14 and
body ground.
Check for loose terminals in the VSA
modulator-control unit 37P connector. If necessary,
substitute a known-good VSA modulator-control
unit (see page 19-171), and retest.
Repair open in the wire between the No. 3
(30 A) fuse in the under-hood fuse/relay box and
the VSA modulator-control unit. 1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn it to
ON (II) again.
4. Operate any one of the four solenoids, as listed, in the VSA FUNCTION TEST five times with the HDS.

1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then start the
engine.
4. Check for DTCs with the HDS.
Go to step 5.
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
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
19-98). If the code resets after clearing, replace the
VSA modulator-control unit (see page 19-171).
Check for loose terminals in the VSA
modulator-control unit 37P connector. If necessary,
substitute a known-good VSA modulator-control
unit (see page 19-171), and retest.
