SYSTEM DESCRIPTION
System ComponentINFOID:0000000005612142
ABS FunctionINFOID:0000000005612143
• The Anti-Lock Brake System detects wheel revolution while braking and improves handling stability during sudden braking by electrically preventing wheel lockup. Maneuverability is also improved for avoiding obsta-
cles.
• If the electrical system malfunctions, the Fail-Safe function is activated, t he ABS becomes inoperative and
the ABS warning lamp turns on.
• The electrical system can be diagnosed using CONSULT-III.
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is normal.
• Just after starting the vehicle, the brake pedal may vibrate or a motor operating noise may be heard from engine compartment. This is a normal status of operation check.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads.
EBD FunctionINFOID:0000000005612144
• Electronic Brake Distribution is a function that detects subtle slippages between the front and rear wheelsduring braking, and it improves handling stability by elec tronically controlling the brake fluid pressure which
results in reduced rear wheel slippage.
• If the electrical system malfunctions, the Fail-Safe function is activated, the EBD and ABS become inopera- tive, and the ABS warning lamp and BRAKE warning lamp are turned on.
• The electrical system can be diagnosed using CONSULT-III.
• During EBD operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting the vehicle, the brake pedal may vibrate or a motor operating noise may be heard from engine compartment. This is a normal status of operation check.
• Stopping distance may be longer than that of vehicles without EBD when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.

If contaminated, flush the engine cooling system.
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. Install the reservoir
tank and cylinder block drain plug, if removed for a total
system drain or for engine removal or repair.
• The radiator must be completely empty of coolant and water.
• Apply sealant to the threads of the cylinder blo ck drain plugs. Use Genuine High Performance
Thread Sealant or equivalent. Refer to GI-42, "
Recommended Chemical Product and Sealant".
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.
4. Install the Tool by installing the radiator cap adapter onto the radiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the coolant mixture container that is placed at floor level. Make sure the ball valve is in the closed
position.
•Use Genuine NISSAN Long Life Anti-freeze coolant or
equivalent, mixed with distil led water or demineralized
water.
Refer to MA-15, "
Anti-freeze Coolant Mixture Ratio".
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Coolant will be visible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. Th is will purge any air trapped in the refill hose.
8. Continue to draw the vacuum until the gauge reaches 28 inches of vacuum. The gauge may not reach 28 inches in high altitude
locations, use the vacuum specifications based on the altitude
above sea level.
9. When the vacuum gauge has reached the specified amount, disconnect the air hose and wait 20 seconds
to see if the system loses any vacuum. If the vacuum level drops, perform any necessary repairs to the
system and repeat steps 6 - 8 to br ing the vacuum to the specified amount. Recheck for any leaks.

PRECAUTIONS
6. Perform a self-diagnosis check of a
ll control units using CONSULT-III.
Precaution for On Board Diagnosis (OBD) System of CVT and EngineINFOID:0000000005397760
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
• Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/sho rt circuit of related switches, sensors, solenoid
valves, etc. will cause the MIL to light up.
• Be sure to connect and lock the connectors secure ly after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
• Be sure to route and secure th e harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
• Be sure to connect rubber tubes properly afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system, etc.
• Be sure to erase the unnecessary malfunction informa tion (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Service After Replacing TCM and Transaxle AssemblyINFOID:0000000005525365
SERVICE AFTER REPLACING TCM AND TRANSAXLE ASSEMBLY
Perform the applicable service according to the following table when replacing TCM or transaxle assembly.
CAUTION:
• Never start the engine unti l the service is completed.
• “DTC P1701” may be indicated soon after replaci ng TCM or transaxle assembly (after erasing the
memory in the pattern B). Restart the self-diagnos is after erasing the self-diagnosis result using
CONSULT-III. Check that no error is detected.
NOTE:
Old unit means that the unit has been already used for another vehicle.

1. Shift the selector lever to “P” position after replacing TCM.
2. Turn ignition switch ON.

necessary.
- The harness between TCM and ROM ASSY in tr ansaxle assembly is open or shorted.
- Terminals disconnected, loose, or bent from connector housing.
PATTERN B
1. Turn ignition switch ON after replacing each part.
2. Connect the vehicle with CONSULT-III.
3. Start engine.

Diagnosis DescriptionINFOID:0000000005398277
INTRODUCTION
The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
*: Service $0A is not applied for regions where it is not mandated.
The above information can be checked using procedures listed in the table below.
×: Applicable —: Not applicable
*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to EC-465,
"FailSafe".)
TWO TRIP DETECTION LOGIC
When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic item s will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.
