DIAGNOSTIC PROCEDURE 1
Check “B” Terminal Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR “B” 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. Make sure that the starter motor B terminal E313 terminal 2 (B)
*1 or (B/R)*2 connection is clean and tight.
5. Check voltage between starter motor B terminal E313 terminal 2
(B)
*1 or (B/R)*2 and ground using a digital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> GO TO 2.
NG >> Check harness between the battery and the starter
motor for open circuit.
2. CHECK BATTERY HARNESS CONNECTION (VOLTAGE DROP TEST)
Check voltage between starter motor B terminal E313 terminal 2
(B)
*1 or (B/R)*2 and battery positive terminal using a digital circuit
tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the 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 using a digital circuit tester.
OK or NG
OK >> Starter motor “B” terminal circuit is OK. Further inspec-
tion necessary. Refer to SC-14, "
WORK FLOW" .
NG >> Check the starter motor case and ground for poor conti-
nuity. Battery voltage should exist.

DIAGNOSTIC PROCEDURE 2
Check “S” Connector Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR “S” CONNECTOR
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 S connector.
5. Check voltage between starter motor harness connector E312
*1
or F33*2 terminal 1 (B) and ground using a digital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> GO TO 2.
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 (intelligent power distribution module engine room)].
Harness for open or short
2. CHECK “S” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Turn ignition switch OFF.
2. Connect starter motor S connector.
3. Check voltage between starter motor harness connector E312
*1
or F33*2 terminal 1 (B) and battery positive terminal using a dig-
ital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> Starter motor “S” connector circuit is OK. Further inspec-
tion necessary. Refer to SC-14, "
WORK FLOW" .
NG >> Check harness between the battery and the starter motor “S” connector for poor continuity.

AWD SYSTEMPFP:41650
Power Transfer DiagramADS000RV
System DescriptionADS000RW
DESCRIPTION
Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close
to rear-wheel drive.
Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:
When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to rear-wheel drive conditions.) Also, optional distri-
bution of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.
If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AWD system will be restored.
When driving, AWD warning lamp may flash slowly if there is a significant difference in diameter of the
tires. At this time, vehicle performance is not fully available and cautious driving is required. (Continues
until engine is turned OFF.)
If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
When the difference of revolution speed between the front and rear wheel with AUTO mode the shift occa-
sionally changes to direct 4-wheel driving conditions automatically. This is not malfunction.
