2007 NISSAN 350Z dead battery

EC-90
TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z

When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when
there is malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected
as NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by
means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MIL circuit are detected and demands
the driver to repair the malfunction.
Symptom Matrix ChartNBS0003G
SYSTEM — BASIC ENGINE CONTROL SYSTEM
Engine operating condition in fail-safe mode Engine speed will not rise more than 2,500 rpm due to the fuel cut

DTC P1212 TCS COMMUNICATION LINE
Revision: 2006 November2007 350Z
DTC P1212 TCS COMMUNICATION LINEPFP:47850
DescriptionNBS000DA
NOTE:

If DTC P1212 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-151, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .

If DTC P1212 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to EC-154, "
DTC U1010 CAN COMMUNICATION" .
This CAN communication line is used to control the smooth engine operation during the TCS operation. Pulse
signals are exchanged between ECM and VDC/TCS/ABS control unit (with VDC models) or “ABS actuator
and electric unit (control unit)” (without VDC models).
Be sure to erase the malfunction information such as DTC not only for VDC/TCS/ABS control unit
(with VDC models) or “ABS actuator and electric unit (control unit)” (without VDC models) but also for
ECM after TCS related repair.
On Board Diagnosis LogicNBS000DB

Freeze frame data is not stored in the ECM for this self-diagnosis.

The MIL will not light up for this self-diagnosis.
DTC Confirmation ProcedureNBS000DC
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.
WITH CONSULT-III
1. Start engine and let it idle for at least 10 seconds.
2. Check 1st trip DTC.
3. If 1st trip DTC is detected, go to EC-542, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III” above.
Diagnostic ProcedureNBS000DD
Go to BRC-82, "TROUBLE DIAGNOSIS" (With VDC models) or BRC-42, "TROUBLE DIAGNOSIS" (Without
VDC models).
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P1212
1212TCS communication
lineECM can not receive the information
from VDC/TCS/ABS control unit (with
VDC models) or “ABS actuator and elec-
tric unit (control unit)” (without VDC mod-
els) continuously.
