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.

16. If necessary, remove the side curtain airbag mounting bolt (A) and grab handle bracket
mounting bolts (B), then remove the grab handle
bracket (C) from each side by releasing the hooks
(D). 17. Install the headliner in the reverse order of removal,
and note these items:
 If the side curtain airbag has deployed, replace the headliner and related parts with new ones
(see page 24-185).
 To prevent the side curtain airbags from deploying improperly and possibly causing
injury, inspect the removed pieces and replace
them if they have any of the following damage:
– Any crease or tears in the headliner (A)
– Any cracks or breakage in the grab handle (B)
– Any damages around the grab handle holes (C) or sunvisor holes in the headliner
– Any cracks in the sunvisor stay base (D)
– Any bends or cracks in the sunvisor stay shaft (E)
– Any cracks in the sunvisor base (F)
– Any cracks or breakage in the vanity mirror base (G)
– Any Velcro fasteners (H) and the clip bases (I) which have come off the headliner
 When installing the grab handle, push on the grab handle against the bracket (J) until the clips
(K) snap into place securely.
 If the clips are damaged or stress-whitened, replace them with new ones.
 Replace the removed cushion tape with new ones.
 Check that both sides of the headliner are securely attached to the trim.
 Make sure the headliner overlaps the trim pieces correctly (see page 24-187).
 When reinstalling the headliner through the front passenger’s door opening, be careful not to fold
or bend it. Also, be careful not to scratch the
body.
 Check for any DTCs that may have been set during repairs, and clear them.
 Do the battery terminal reconnection procedure (see page 22-68).
