Description
NHEC0540
The malfunction information related to ABS/TCS control unit is
transferred through the line (LAN) from ABS/TCS control unit to
ECM.
Be sure to erase the malfunction information such as DTC not
only for ABS/TCS control unit but also for ECM after the ABS/
TCS related repair.
DTC ERASING PROCEDURE FOR ABS/TCS RELATED
REPAIR
NHEC0540S01
1) Turn ignition switch “OFF” and then turn it “ON”.
2) Connect CONSULT-II and select “ABS”.
3) Select “ABS” and touch “SELF-DIAG RESULTS”.
4) Touch “ERASE”.
5) Touch “BACK” then erase malfunction code which has been
stored in the TCM or ECM.
On Board Diagnosis Logic
NHEC0542
Freeze frame data is not stored in the ECM for the ABS/TCS
control unit. The MIL will not light up for ABS/TCS control unit.
Malfunction is detected when
(Malfunction A) ECM receives incorrect voltage from ABS/TCS
control unit continuously,
(Malfunction B) TCS operation (Fuel cut) continues for an abnor-
mally long time.
Possible Cause
NHEC0543
I ABS/TCS control unit
I TCS related parts (Refer to BR section.)
SEF058Y

cannot be confirmed, perform “Overall Function Check”, “Pro-
cedure for malfunction B”.
PROCEDURE FOR MALFUNCTION A

TESTING CONDITION:
Before performing the following procedure, confirm that bat-
tery voltage is more than 10.5V at idle.
