DTC U1010 CAN COMMUNICATION
2007 Versa
DTC U1010 CAN COMMUNICATIONPFP:23710
DescriptionUBS00QC2
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 LogicUBS00QC3
This self-diagnosis has the one trip detection logic (A/T, CVT).
The MIL will not light up for this self-diagnosis (M/T).
DTC Confirmation ProcedureUBS00QC4
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. If 1st trip DTC is detected, go to EC-155, "
Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

DTC P0011 IVT CONTROL
2007 Versa
DTC P0011 IVT CONTROLPFP:23796
DescriptionUBS00QC6
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN communication line.
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve. The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine
coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control sole-
noid valve depending on driving status. This makes it possible to control the shut/open timing of the intake
valve to increase engine torque in low/mid speed range and output in high-speed range.

FAIL-SAFE MODE
ECM enters in fail-safe mode when the malfunction is detected.
DTC Confirmation ProcedureUBS00QC9
CAUTION:
Always drive at a safe speed.
NOTE:
If DTC P0011 is displayed with DTC P0075, first perform trouble diagnosis for DTC P0075.
See EC-173, "
DTC P0075 IVT CONTROL SOLENOID VALVE" .
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10V and 16V at
idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and warm it up to the normal operating tempera-
ture.
3. Maintain the following conditions for at least 6 consecutive sec-
onds.
Hold the accelerator pedal as steady as possible.
4. Let engine idle for 10 seconds.
5. If 1st trip DTC is detected, go to EC-158, "
Diagnostic Procedure" .
If 1st trip DTC is not detected, go to next step.
