DTC P1212 TCS COMMUNICATION LINE
Revision: 2006 July 2007 FX35/FX45
DTC P1212 TCS COMMUNICATION LINEPFP:47850
DescriptionNBS004CO
NOTE:

If DTC P1212 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-820, "
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-823, "
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 “ABS actuator and electric unit (control unit)”.
Be sure to erase the malfunction information such as DTC not only for “ABS actuator and electric unit
(control unit)” but also for ECM after TCS related repair.
On Board Diagnosis LogicNBS004CP
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 ProcedureNBS004CQ
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 10 seconds.
4. If 1st trip DTC is detected, go to EC-1172, "
Diagnostic Proce-
dure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.
Diagnostic ProcedureNBS004CR

DTC P1574 ICC VEHICLE SPEED SENSORPFP:31036
Component DescriptionNBS004EO
The ECM receives two vehicle speed signals via CAN communication line. One is sent from “unified meter and
A/C amp.”, and the other is from TCM (Transmission control module). The ECM uses these signals for ICC
control. Refer to ACS-6, "
DESCRIPTION" for ICC functions.
On Board Diagnosis LogicNBS004EP
This self-diagnosis has the one trip detection logic.
The MIL will not light up for this diagnosis.
NOTE:

If DTC P1574 is displayed with DTC U1000, U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-820, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .

If DTC P1574 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to EC-823, "
DTC U1010 CAN COMMUNICATION" .

If DTC P1574 is displayed with DTC P0500, first perform the trouble diagnosis for DTC P0500.
Refer to EC-1133, "
DTC P0500 VSS" .

If DTC P1574 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605.
Refer to EC-1148, "
DTC P0605 ECM".
DTC Confirmation ProcedureNBS004EQ
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
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:

is expected to be easier, it is unnecessary to lift the vehicle.
WITH CONSULT-II
1. Start engine (VDC switch OFF).
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Drive the vehicle at more than 40 km/h (25MPH).
4. If DTC is detected, go to EC-1224, "

4. Remove fuel feed hose (with damper) from fuel sub-tube.
NOTE:
There is no fuel return route.
CAUTION:

While hoses are disconnected, plug them to prevent fuel
from draining.

Do not separate damper and hose.
5. When separating fuel feed hose (with damper) and centralized under-floor piping connection, disconnect quick connector as the following:
a. Remove quick connector cap from quick connector connection on right member side.
b. Disconnect fuel feed hose (with damper) from bracket hose clamp.
c. Disconnect quick connector from centralized under-floor piping as follows: CAUTION:
Disconnect quick connector by using quick connector release [SST: — (J-45488)], not by picking
out retainer tabs.
i. With the sleeve side of quick connector release facing quick connector, install quick connector release onto centralized under-floor piping.
ii. Insert quick connector release into quick connector until sleeve contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector release hard will not disconnect
quick connector. Hold quick connector release where it
contacts and goes no further.
iii. Draw and pull out quick connector straight from centralized under-floor piping.
CAUTION:

Pull quick connector holding “A” position as shown in
the figure.

Do not pull with lateral force applied. O-ring inside quick connector may be damaged.

Prepare container and cloth beforehand as fuel will leak out.

Avoid fire and sparks.

Keep parts away from heat source. Especially, be careful when welding is performed around
them.

Do not expose parts to battery electrolyte or other acids.

Do not bend or twist connection between quick connector and fuel feed hose (with damper) dur-
ing installation/removal.
