DTC P1212 TCS COMMUNICATION LINE
PFP:47850
Description
EBS013QN
NOTE:
If DTC P1212 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
EC-83, "DTC U1000 CAN COMMUNICATION LINE"
.
This CAN communication line is used to control the smooth engine operation during the TCS operation. Pulse
signals are exchanged between ECM and ESP/TCS/ABS control unit.
Be sure to erase the malfunction information such as DTC not only for ESP/TCS/ABS control unit but
also for ECM after TCS related repair.
On Board Diagnosis Logic
EBS013QO
This self-diagnosis has the one trip detection logic.
The MI will not light up for this self-diagnosis.
DTC Confirmation Procedure
EBS013QP
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.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Wait at least 5 seconds.
4.
If DTC is detected, go to
EC-265, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
Diagnostic Procedure
EBS013QQ
1.
CHECK ESP/TCS/ABS CONTROL UNIT FUNCTION
Refer to
(models with ESP system) or
(models without ESP system).
>> INSPECTION END
DTC No.
Trouble diagnosis name
DTC detecting condition
Possible cause
P1212
TCS communication line
ECM can not receive the information from ESP/
TCS/ABS control unit continuously.
●
Harness or connectors
(The CAN communication line is
open or shorted.)
●
ESP/TCS/ABS control unit
●
Dead (Weak) battery

DTC P1260 - P1267 FUEL INJECTOR ADJUSTMENT RESISTOR
DTC P1260 - P1267 FUEL INJECTOR ADJUSTMENT RESISTOR
PFP:16600
Description
EBS013QR
The fuel injector adjustment resistor is built into the fuel injector. The resistance is constant and individual.
ECM uses the individual resistance to determine the fuel injection pulse.
ECM Terminals and Reference Value
EBS013QS
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
