DTC P1587 CAN COMMUNICATION ERROR (MT/AT RECOGNITION ERROR)
COMPONENT LOCATION
EB68EEA9
Refer to DTC P1586.
GENERAL DESCRIPTION
E3BE21DD
Refer to DTC P1586.
DTC DESCRIPTION
EB5354F4
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 normal for each
vehicle option, if no problem is detected, check poor connection in CAN communication circuit or CAN communication
problem of TCM.

FUEL SYSTEM
YES
▶ Go to "Check CAN communication line".
Refer to "U0101" DTC guide for checking CAN communication line.
NO
▶ Repair poor connection or open in C142 joint connector 17 termianl 20 and G102 ground point related circuit and
go to "Verification of Vehicle Repair".
VERIFICATION OF VEHICLE REPAIR
E4554621
After a repair, it is essential to verify that the fault is corrected.
1.
After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.
2.
Clear recorded DTC using Scantool.
3.
Drive the vehicle within DTC "Enable conditions" in "General information".
4.
After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.
5.
Are any DTCs recorded ?
YES
▶ Go to the DTC guide of recorded NO. in Scantool.
NO
▶ System operates within specification.

DTC P1588 SIGNAL CHANGE THROUGH MT/AT LINE (DURING ENGINE
RUNNING)
COMPONENT LOCATION
EA850174
Refer to DTC P1586.
GENERAL DESCRIPTION
E50FAA4B
Refer to DTC P1586.
DTC DESCRIPTION
E4B03891
P1588 is set when the signal from A/T, M/T auto recognition terminal(ECM C101-2 terminal 81) changes during engine
run. This code is due to open in terminal for A/T option, grounded condition for M/T option. This code is normally arises
from A/T option vehicle. Check the grounding condition of A/T, M/T auto recognition terminal.
