PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
PRECAUTIONSPFP:00001
CautionsNES000G0

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

Unladen conditions means that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

DIAGNOSTIC PROCEDURE 2
Check “S” Connector Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR “S” TERMINAL
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn ignition switch OFF.
4. Disconnect starter motor connector.
5. Check voltage between starter motor harness connector E312 (VK45DE) or F33 (VQ35DE) terminal 1 and ground.
OK or NG
OK >> “S” connector circuit is OK. Further inspection neces- sary. Refer to SC-15, "
WORK FLOW" .
NG >> Check the following.

40A fusible link (letter F , located in fuse and fusible
link box)

Ignition switch

Starter relay (within the IPDM E/R)

Harness for open or short
