FUEL SYSTEM
DTC P1587 CAN COMMUNICATION ERROR (MT/AT RECOGNITION ERROR)
GENERAL DESCRIPTION
EA2971F0
Because both A/T and M/T fuel control map is inputted in one type of ECM and selecting option is possible, one type
is applied to both A/T and M/T option.When ECM is installed to vehicle, A/T and M/T recognition is performed by ECM
automatically as checking whether ground line(ECM connector C230-K terminal 81) is grounded or opened.(A/T and M/T
recognition is performed every IG KEY ON process.) If A/T, M/T recognition is not fulfilled well or any error occurs during
the process, engine power generation is not sufficient and glow lamp on cluster blinks.
A/T : ECM connector C230-K terminal 81 is grounded
M/T : ECM connector C230-K terminal 81 is opened(no wiring exists)
DTC DESCRIPTION
EA904FAB
P1587 is set when ECM is recognized as 1)A/T but CAN communication signal is not transmitted from TCM 2)M/T but
CAN communication signal is transmitted from TCM. After checking if A/T, M/T auto recognition terminal is correct for each
vehicle option, if no problem is detected, check poor connection in CAN communication circuit or CAN communication
problem of TCM.

TERMINAL AND CONNECTOR INSPECTION
EE2299F2
1.
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various prob-
lems and damge of component.
2.
Perform checking procedure as follows.
1)
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
DTC TROUBLESHOOTING PROCEDURES
FL -429
2)
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking
device and connecting condition between terminal and wiring.
NOTE
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for
checking connecting condition. ( after checking, reconnect the pin at correct position. )
3.
Is the problem found?
YES
▶
Repair the trouble causing part and go to "Verification of Vehicle Repair".
NO
▶
Go to "Ground Circuit Inspection".
GROUND CIRCUIT INSPECTION
E47C0B26
1.
IG KEY "OFF", ENGINE "OFF".
2.
Disconnect ECM connector.
3.
Check continuity between ECM connector(C230-K) terminal 81 and chassis ground.
Specification : Continuity (below 1.0
Ω
)
4.
Is A/T, M/T auto recognition terminal grounded well?
YES
▶
Go to "CAN communication line inspection".
NO
▶
Repair poor connection or open in G15 ground point related circuit and go to "Verification of Vehicle Repair".
CAN COMMUNICATION LINE INSPECTION
1.
Check CAN BUS vertical resistance
1)
IG KEY "OFF", ENGINE "OFF"
2)
Measure the resistance between DLC terminal 3 and 11.
3)
Disconnect ECM connector.
4)
Measure the resistance between DLC terminal 3 and 11.
Specification : Both ECM and TCM are connected : 60 ± 3
Ω
Both ECM and TCM are disconnected : 120 ± 3
Ω
5)
Is measured CAN BUS vertical resistance value within the specification?
YES
