DTC U1010 CAN COMMUNICATION
Revision: 2006 November2007 350Z
DTC U1010 CAN COMMUNICATIONPFP:23710
DescriptionNBS002VL
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicNBS006T4

This self-diagnosis has one trip detection logic (A/T models).

The MIL will not light up for this self-diagnosis (M/T models).
DTC Confirmation ProcedureNBS002VN
WITH CONSULT-III
1. Turn ignition switch ON.
2. Check DTC.
3. If DTC is detected, go to EC-155, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III” above.
DTC No. Trouble diagnosis name DTC detecting condition Possible cause

6. CHECK TIMING CHAIN INSTALLATION
Check service records for any recent repairs that may cause timing chain misaligned.
Are there any service records that may cause timing chain misaligned?
Ye s o r N o
Yes >> Check timing chain installation. Refer to EM-53, "TIMING CHAIN" .
No >> GO TO 7.
7. CHECK LUBRICATION CIRCUIT
Refer to EM-74, "
INSPECTION AFTER REMOVAL" .
OK or NG
OK >> GO TO 8.
NG >> Clean lubrication line.
8. CHECK INTERMITTENT INCIDENT
Refer to EC-141, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
For Wiring Diagram, refer to EC-388
for crankshaft position sensor (POS) and EC-397 for camshaft position
sensor (PHASE).

Component InspectionNBS0004A
INTAKE VALVE TIMING CONTROL SOLENOID VALVE
1. Disconnect intake valve timing control solenoid valve harness connector.
2. Check resistance between intake valve timing control solenoid
valve as follows.
If NG, replace intake valve timing control solenoid valve.
If OK, go to next step.
3. Remove intake valve timing control solenoid valve.
4. Provide 12V DC between intake valve timing control solenoid
valve terminals and then interrupt it. Make sure that the plunger
moves as shown in the figure.
CAUTION:
Do not apply 12V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
If NG, replace intake valve timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed.

2. CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
1. Disconnect air fuel ratio (A/F) sensor 1 harness connector.
2. Turn ignition switch ON.
3. Check voltage between air fuel ratio sensor (A/F) sensor 1 ter-
minal 4 and ground with CONSULT-III or tester.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING PART
Check the following.

Harness connectors E12, F3
