TROUBLE DIAGNOSIS
Revision: 2006 July 2007 FX35/FX45
Note 1: After completing repairs of shorted sensor circuit, when turning ignition switch ON, ABS warning lamp turned on. Make t hat ABS
warning lamp turned off while driving vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute according to self-
diagnosis procedure. In addition, if wheel sensor 2 is displayed for wheels, check wheel sensor circuit and also check ABS actu ator and
electric unit (control unit) power voltage.
Note 2: If multiple malfunctions are detected including CAN communication line [U1000], perform diagnosis for CAN communication line
first.
Note 3: “ACTUATOR RLY” on the CONSULT-II self-diagnostic results indicates the malfunction of actuator relay or circuit. Actuat or relay
is imbedded in ABS actuator and electric unit (control unit).
Note 4:Only AWD models. DECEL G SEN SET

TEST ITEM
Solenoid Valve
NOTE:
The example shown is for the front right wheel. The procedure for the other wheels is the same as given
below.

When performing an active test of the ABS function, select the
main item for each test item. In addition, when performing an
active test of the VDC/TCS function, select the item menu for
each test item.

For the ABS solenoid valve, touch “UP” “KEEP” “DOWN”, and
for the ABS solenoid valve (ACT), touch “UP” “ACTUATOR UP”
“ACTUATOR KEEP”, and check to make sure that all solenoid
valve (in, out) are operating as given in the table below.
*: ON for 1 to 2 seconds after the touch, and then OFF
NOTE:

If active test is performed with brake pedal depressed, pedal stroke may change. This is normal.

“TEST IS STOPPED” is displayed approximately 10 seconds after operation starts.

After “TEST IS STOPPED” is displayed, touch “BACK” and perform the test from the Step 8.
ABS Motor
Touch “ON” and “OFF” on the screen. Make sure ABS motor relay
operates as shown in table below.
NOTE:

If active test is performed with brake pedal depressed, pedal
stroke may change. This is normal.

“TEST IS STOPPED” is displayed approximately 10 seconds
after operation starts.

REAR VIEW MONITORPFP:28260
System DescriptionNKS0031T

The rear view monitor is equipped to check the rearward of the vehicle with display when A/T selector
lever is in reverse position.

The lines of vehicle sides and the distance from the rear end of the vehicle are provided on display as a
guide. It allows the driver to know the distance between the vehicle and a rearward object, and the width
of the vehicle much easier.
POWER SUPPLY AND GROUND
Power is supplied at all time

through 10A fuse [No. 19, located in fuse block (J/B)]

to rear view camera control unit terminal 1.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to rear view camera control unit terminal 2.
When ignition switch is in ON or START position, power is supplied

through 10A fuse (No. 83, located in IPDM E/R)

to back-up lamp relay terminals 1 and 3.
Ground is supplied

to rear view camera control unit terminal 3

through grounds M35, M45 and M85.
AV COMMUNICATION LINE
Rear view camera control unit is connected to the following units with AV communication line. Each unit trans-
mits/receives data with AV communication line.

NAVI control unit

Display

Display control unit

A/C and AV switch
REAR VIEW CAMERA OPERATION
When A/T selector lever is reverse position, power is supplied

through back-up lamp relay terminal 2

to TCM terminal 7.
Then back-up lamp relay is energized,

from back-up lamp relay terminal 5

to rear view camera control unit terminal 4.
Then, rear view camera control unit is sent camera ON signal

through rear view camera control unit terminal 8

to rear view camera terminal 1.
An image taken by rear view camera is sent

through rear view camera terminals 3 and 4

to rear view camera control unit terminals 10 and 9.
Then an image is sent

through rear view camera control unit terminals 12 and 14

to the display terminals 15 and 16.
An image of rear view will be projected on the display.

1. BACK-UP LAMP INSPECTION
1. Turn ignition switch ON.
2. Shift A/T selector lever to R position.
Does back-up lamp illuminate?
YES >> GO TO 2.
NO >> Check back-up lamp system. Refer to LT- 1 2 9 , "
BACK-UP LAMP" in LT section.
2. CHECK REVERSE POSITION INPUT SIGNAL
With CONSULT-II
1. Select “DATA MONITOR” of “REARVIEW CAMERA”.
2. Operate ignition switch with “R POSI SIG” of “DATA MONITOR” and check operate status.
Without CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect rear view camera control unit connector.
3. Turn ignition switch ON.
4. Shift A/T selector lever to R position.
5. Check voltage between rear view camera control unit harness connector M48 terminal 4 and ground.
