Fail SafeINFOID:0000000004171221
FAIL-SAFE CONTROL
Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and
direction of door glass. Switches to fail-safe cont rol when error beyond regulation value is detected between
the fully closed position and the actual position of the glass.

PWC-96
< ECU DIAGNOSIS >
FRONT POWER WINDOW SWITCH
It changes to condition before initialization and the following functions do not operate when switched to fail-
safe control.
 Auto-up operation
 Anti-pinch function
 Retained power function
Perform initial operation to recover when switched to fa il-safe mode. However, it switches back to fail-safe
control when malfunction is found in power window switch or in motor.
Error Error condition
Pulse sensor malfunction When only one side of pulse signal is being detected for more than the specified value.
Both pulse sensors mal-
function When both pulse signals have not been detected for more than the specified value during glass open/
close operation.
Pulse direction malfunction When the pulse signal that is detected during glass open/close operation detects the opposite condition
of power window motor operating direction.
Glass recognition position
malfunction 1 When it detects the error between glass fully closed position in power window switch memory and actual
fully closed position during glass open/close operation is more than the specified value.
Glass recognition position
malfunction 2 When it detects pulse count more than the value of glass full stroke during glass open/close operation.
Malfunction of not yet up-
dated closed position of
glass When glass open/close operation is continuously performed without fully closing more than the specified
value (approximately 10 strokes).

5. Remove the snap ring using a suitable tool, then remove the ballcage, steel ball, inner race assembly from the drive shaft.
6. Remove the boot from the drive shaft.
7. Remove any old grease on the housing using paper towels.
Wheel Side
1. Secure the drive shaft in a vise. CAUTION:
When securing the drive shaft in a vise, use copp er or aluminum plates between the vise and the
drive shaft.
2. Remove the boot bands, then remove the boot from the joint sub-assembly.
3. Screw a suitable drive shaft puller 30 mm (1.18 in) or more into the threaded part of the joint sub-assembly. Pull the joint sub-
assembly out of the drive shaft as shown.
CAUTION:
 If the joint sub-assembly cannot be removed after five ormore attempts, replace the drive shaft and joint sub-
assembly as a set.
 Align the sliding hammer and drive shaft and remove the
joint sub-assembly by pulling directly.
4. Remove the boot from the drive shaft.
5. Remove the circlip from the drive shaft.
6. While rotating the ball cage, remove any old grease on the joint sub-assembly using paper towels.
INSPECTION AFTER DISASSEMBLY
Drive Shaft
 Replace the drive shaft if there is any runout, cracking, or other damage.
Joint Sub-assembly
 Check for any rough rotation or unusual axial looseness.
 Clean any foreign material from inside the joint sub-assembly.
 Check for any compression scars, cracks, or fractures.
CAUTION:
If any defective conditions are found in the joint sub-assembly comp onents, replace the entire joint
sub-assembly.
Sliding Joint Side (Housing)
 Check for any compression scars, cracks, fracture s, or unusual wear on the ball rolling surface.
 Check for any damage to the drive shaft screws.
 Check for any deformation of the boot installation components.
Ball Cage
 Check the sliding surface for any compression scars, cracks, or fractures.
Steel Ball
 Check for any compression scars, cr acks, fractures, or unusual wear.

ASSEMBLY
Final Drive Side
1. If the plug has been removed, use Tool to press in a new one.
NOTE:
Discard the old plug and use a new one for assembly.
2. Wrap the serrated part of the shaft with tape. Install the boot band and boot to shaft.
NOTE:
Discard the old boot band and boot and use a new one for
assembly.
3. Remove the tape wound around the serrated part of the shaft.
4. Install the ball cage, steel ball, and inner race assembly on the shaft, and secure them tightly using the snap ring.
NOTE:
Discard the old snap ring and use a new one for assembly.
5. Insert the specified quantit y of Genuine NISSAN Grease or
equivalent, onto the housing (indicated by * marks), and install it
onto shaft. Refer to MA-12, "Fluids and Lubricants"
.
6. Install the stopper ring onto the housing. Tool number : KV38100500 ( — )

7. After installation, pull on the shaft to check engagement between the joint sub-assembly and the stopper
ring.
8. Install the boot securely into the grooves (indicated by * marks) as shown.
CAUTION:
If there is grease on boot mating surfaces (indicated by*
marks) of shaft and housing, boot may come off. Remove
all grease from surfaces.
9. Check that the boot installation length (L) is the length indicated below. Insert a suitable tool into large side of the boot. Bleed the
air from the boot to pr event any boot deformation.
CAUTION:
 The boot may break if the boot installation length is less than the specified value.
 Do not to touch the tip of the t ool to the inside of the boot.
10. Secure the large and small ends of the boot with the new boot bands as shown.
NOTE:
Discard the old boot bands and use new ones for assembly.
11. After installing the housing and shaft, rotate the boot to check that the boot is positioned correctly. If the
boot is not positioned correctly, reposition the boot and secure the boot using a new boot band.
Wheel Side
1. Insert the Genuine NISSAN Grease or equivalent, into the joint
sub-assembly serration hole until the grease begins to ooze
from the ball groove and serration hole. Refer to MA-12, "Fluids
and Lubricants". After inserting the grease, use a shop cloth to
wipe off the grease that has oozed out.
2. Wind the serrated part of the shaft with tape. Install the boot
band and boot onto the shaft. Do not damage the boot.
