CAUTION:

Do not perform ACTIVE TEST while driving vehicle.

Make sure to completely bleed air from brake system.

Active test cannot be performed when ABS warning lamp is turned on.

ABS and brake warning lamps turn on during active test.
OPERATION PROCEDURE
1. Perform “CONSULT-II Starting procedure”. Refer to GI-34, "CONSULT-II Start Procedure" .
2. Touch “ACTIVE TEST” in order on the CONSULT-II screen.
3. The “ SELECT TEST ITEM” screen is displayed.
4. Touch necessary test item.
5. Touch “START” with “MAIN SIGNALS” line inverted.
6. ACTIVE TEST screen will be displayed, so perform the following test.

Solenoid valve

ABS motor
NOTE:

When active test is performed while depressing brake pedal, the pedal height will change, but this is
normal.

Approximately 10 seconds after operation has begun, “TEST STOP” will be displayed.

To perform a retest after “TEST STOP” is displayed, touch “BACK” and perform test from step 3.

CAUTION:

Do not perform active test while driving vehicle.

Make sure to completely bleed air from brake system.

Active test cannot be performed while ABS warning lamp is turned on due to the ABS malfunction-
ing.

ABS and brake warning lamps are on during active test.
OPERATION PROCEDURE
1. Preform “CONSULT-II Starting Procedure”. Refer to GI-34, "CONSULT-II Start Procedure" .
2. Touch “ACTIVE TEST” in order on the CONSULT-II screen.
CAUTION:
When “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on
ignition switch, “ABS” might not be displayed in the system selection screen. In this case, repeat
the operation from step 1.
3. The “SELECT TEST ITEM” is displayed.
4. Touch necessary test item.
5. While “MAIN SIGNALS” indication is inverted, touch “START”.
6. “ACTIVE TEST” screen will be displayed, so perform the following test.

Checking of CVT PositionBCS001MO
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transaxle body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps do not illuminate
when the selector lever is pushed toward the “R” position side
with the gear position remained in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.
8. Make sure transaxle is locked completely in “P” position.
9. When selector lever is set to manual shift gate, make sure man-
ual mode is displayed on combination meter.
Shift selector lever to “+” and “-” sides, and make sure set shift position changes.

Always ECM returns to Diagnostic Test Mode I after ignition switch is turned OFF.
How to Set Diagnostic Test Mode II (Self-Diagnostic Results)
1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the MI starts
blinking.
4. Fully release the accelerator pedal.
ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).
How to Set Diagnostic Test Mode II (Heated Oxygen Sensor 1 Monitor)
1. Set the ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-38, "How to Set Diagnostic
Test Mode II (Self-Diagnostic Results)" .
2. Start Engine.
ECM has entered to Diagnostic Test Mode II (Heated oxygen sensor 1 monitor).
How to Erase Diagnostic Test Mode II (Self-Diagnostic Results)
1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-38, "How to Set Diagnostic Test
Mode II (Self-Diagnostic Results)" .
2. Fully depress the accelerator pedal and keep it for more than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.
DIAGNOSTIC TEST MODE I — BULB CHECK
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to DI-35,
"WARNING LAMPS" or see EC-344, "MI & DATA LINK CONNECTORS" .
DIAGNOSTIC TEST MODE I — MALFUNCTION WARNING

These DTC numbers are clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC RESULTS)
DIAGNOSTIC TEST MODE II — SELF-DIAGNOSTIC RESULTS
In this mode, the DTC and 1st trip DTC are indicated by the number of blinks of the MI as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MI does not illuminate in diagnostic test mode
I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MI illumi-
nates in diagnostic test mode II (SELF-DIAGNOSTIC RESULTS), it is a DTC; if two or more codes are dis-

INPUT
SIG-
NALSMAIN
SIG-
NALSDescription Remarks
ENG SPEED [rpm]××

Indicates the engine speed computed from
the signals of the crankshaft position sen-
sor (POS) and camshaft position sensor
(PHASE).
Accuracy becomes poor if engine
speed drops below the idle rpm.

If the signal is interrupted while the
engine is running, an abnormal value
may be indicated.
MAS A/F SE-B1 [V]××

The signal voltage of the mass air flow sen-
sor is displayed.
When the engine is stopped, a cer-
tain value is indicated.
B/FUEL SCHDL
[msec]×

“Base fuel schedule” indicates the fuel
injection pulse width programmed into
ECM, prior to any learned on board correc-
tion.
A/F ALPHA-B1 [%]×

The mean value of the air-fuel ratio feed-
back correction factor per cycle is indicated.

When the engine is stopped, a cer-
tain value is indicated.

This data also includes the data for
the air-fuel ratio learning control.
COOLAN TEMP/S
[°C] or [°F]××

The engine coolant temperature (deter-
mined by the signal voltage of the engine
coolant temperature sensor) is displayed.

When the engine coolant tempera-
ture sensor is open or short-circuited,
ECM enters fail-safe mode. The
engine coolant temperature deter-
mined by the ECM is displayed.
HO2S1 (B1) [V]××

The signal voltage of the heated oxygen
sensor 1 is displayed.
HO2S2 (B1) [V]×

The signal voltage of the heated oxygen
sensor 2 is displayed.
HO2S1 MNTR (B1)
[RICH/LEAN]××

Display of heated oxygen sensor 1 signal
during air-fuel ratio feedback control:
RICH: means the mixture became “rich”,
and control is being affected toward a
leaner mixture.
LEAN: means the mixture became “lean”,
and control is being affected toward a rich
mixture.
After turning ON the ignition switch,
“RICH” is displayed until air-fuel mix-
ture ratio feedback control begins.

When the air-fuel ratio feedback is
clamped, the value just before the
clamping is displayed continuously.
HO2S2 MNTR (B1)
[RICH/LEAN]×

Display of heated oxygen sensor 2 signal:
RICH: means the amount of oxygen after
three way catalyst is relatively small.
LEAN: means the amount of oxygen after
three way catalyst is relatively large.

When the engine is stopped, a cer-
tain value is indicated.
VHCL SPEED SE
[km/h] or [mph]××

The vehicle speed computed from the vehi-
cle speed signal sent from combination
meter is displayed.
BATTERY VOLT [V]××

The power supply voltage of ECM is dis-
played.
ACCEL SEN 1 [V]××

The accelerator pedal position sensor sig-
nal voltage is displayed.
ACCEL SEN 2 signal is converted by
ECM internally. Thus, it differs from
ECM terminal voltage signal. ACCEL SEN 2 [V]×
THRTL SEN 1 [V]××

The throttle position sensor signal voltage
is displayed.
