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.
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 voltage is above 15.1 V, 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).
Replace the VSA modulator-control unit
(see page 19-171), and retest. 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.
Go to step 5.
Intermittent failure, the system is OK at this
time.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the steering angle sensor 5P connector.
7. Disconnect the VSA modulator-control unit 37P connector (see step 2 on page 19-171).
