VSA System Components
General Troubleshooting Information (cont’d)
 The memory holds all DTCs. However, when the
same DTC is detected more than once, the more
recent DTC is written over the earlier one. Therefore,
when the same problem is detected repeatedly, it is
memorized as a single DTC.
 The DTCs are indicated in the order they occur.
 The DTCs are memorized in the EEPROM. Therefore, the memorized DTCs cannot be erased by
disconnecting the battery. Do the specified
procedures to clear the DTCs.
 Self-diagnosis can be classified into two categories: – Initial diagnosis: Done right after the ignition switch is turned to ON (II) and until the ABS and VSA
indicators go off.
– Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned to
LOCK (0).
 When the system detects a problem, the VSA modulator-control unit shifts to fail-safe mode.
The pump motor operates when the VSA modulator-
control unit is functioning, and the fluid in the reservoir
is forced out to the master cylinder, causing kickback at
the brake pedal.  The pump motor operates when the VSA modulator- control unit is functioning.
 The VSA modulator-control unit checks the pump motor operation one time after completing initial
diagnosis during regular diagnosis when the vehicle
is driven over 15 km/h (10 mph).
Brake fluid replacement and air bleeding procedures
are identical to the procedures used on vehicles without
the VSA system (see page 19-9). The troubleshooting procedures assume that the cause
of the problem is still present, and the ABS and/or VSA
indicator is still on. Following a troubleshooting
procedure for a code that has been cleared but does not
reset can result in incorrect diagnosis.
1. Question the client about the conditions when the problem occurred, and try to reproduce the same
conditions for troubleshooting. Find out when the
ABS and/or VSA indicator came on, such as during
activation, after activation, when the vehicle was
traveling at a certain speed, etc. If necessary, have
the client demonstrate the concern.
2. When the ABS or VSA indicator does not come on during the test-drive, check for loose connectors,
poor contact of the terminals, etc. in the circuit
indicated by the DTC before you start
troubleshooting.
3. After troubleshooting, or the repairs are done, clear the DTCs, and test-drive the vehicle under the same
conditions that originally set the DTCs. Make sure
the ABS and VSA indicators do not come on.
4. Check for DTCs from other systems which are connected via F-CAN. If there are DTCs that are
related to F-CAN, one possible cause was that the
ignition switch was turned to ON (II) with the VSA
modulator-control unit connector disconnected.
Clear the DTCs. Check for fuel and emissions DTC’s
first.
NOTE: Always troubleshoot fuel and emissions
DTC’s first.
The term ‘‘intermittent failure’’ means a system may
have had a failure, but it checks OK now. If you cannot
reproduce the condition, check for loose connectors or
terminal pins related to the circuit that you are
troubleshooting.

following adjustment:
1. Remove the bracket cover.
2. Adjust the glass (A). –1 Slightly loosen the screws with a TORX T25 bit.
–2 Move the glass up or down and forward orrearward.
–3 Tighten all screws securely.
3. If necessary, repeat on the opposite side. 1. Close the glass fully.
2. Slide the sunshade all the way back.
3. Pry out the lid (A), remove the screws (B), and
release the hooks (C), then remove both bracket
covers (D). Remove the screws (E) with a TORX T25
bit from both glass brackets (F).
4. Remove the glass (A) by lifting it up. Do not damage the roof panel.
5. Install the glass in the reverse order of the removal, and adjust the glass position alignment (see page

6. Reset the moonroof control unit (see page 22-287).
7. Check for water leaks. Use free-flowing water from a hose without a nozzle. Do not use high-pressure
water.
NOTE: It is normal for some water to seep past the
moonroof into the moonroof frame, and exit
through the drains.
