ASSEMBLY
NOTE:
Fix oil pump in vise as vise occasion demands.
CAUTION:
When retaining drive shaft assembly in a vise, always use copper or aluminum plates between vise
and shaft.
1. Apply recommended grease to oil seal lips (1). Apply recom- mended fluid to around oil seal, and then install oil seal to body
assembly.
2. Apply recommended fluid to drive shaft assembly and press drive shaft assembly into body assembly with suitable tool, then
install snap ring.
3. Apply recommended fluid to O-ring and Install O-ring into body assembly.
4. Install side plate to body assembly.
5. Install lock pin into lock pin hole, and install cam-ring as shown in the figure.

When installing cam-ring, turn carved face with a letter (E) of
it to rear cover.
CAUTION:
Do not confuse the assembling direction of cam ring. If
cam ring is installed facing the incorrect direction, it may
cause pump operation malfunction.
6. Install rotor to body assembly.

System Description NKS002UQ
Power is supplied at all times

through 40A fusible link (letter F, located in the fuse and fusible link block)

to ignition switch terminal 1,

through 15A fuse (No. 78, located in the IPDM E/R)

to CPU of IPDM E/R,

through 10A fuse (No. 71, located in the IPDM E/R)

to CPU of IPDM E/R.
When the selector lever in the P or N position, power is supplied

from TCM, and through A/T assembly terminal 9

to IPDM E/R terminal 53.
Ground is supplied

to IPDM E/R terminals 38, 50 and 60

from grounds E21, E50 and E51.
With the ignition switch in the START position, and provided that the IPDM E/R receives a starter relay ON sig-
nal from the CAN lines, the IPDM E/R is energized and power is supplied

from ignition switch terminal 5

to IPDM E/R terminal 4 and

through IPDM E/R terminal 3

to starter motor terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.

3. Turn ignition switch OFF.
4. Make sure that the starter motor “B” terminal E313 terminal 2 connection is clean and tight.
5. Check voltage between starter motor “B” terminal E313 terminal 2 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check harness between battery and starter motor for open circuit.
2. CHECK BATTERY CABLE CONNECTION (VOLTAGE DROP TEST)
Check voltage between starter motor “B” terminal E313 terminal 2
and battery positive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between battery and starter motor for poor continuity.
3. CHECK STARTER MOTOR GROUND CIRCUIT (VOLTAGE DROP TEST)
1. Turn ignition switch OFF.
2. Check voltage between starter motor case and battery negative terminal.
OK or NG
OK >> “B” terminal circuit is OK. Further inspection necessary. Refer to SC-15, "
WORK FLOW" .
NG >> Check starter motor case and ground for poor continuity. 2 – Ground : Battery voltage
