DTC detecting Condition and Trouble Area
DTC confirmation procedure
1) Connect scan tool to DLC with ignition switch turned OFF.
2) Turn ON ignition switch and clear DTC by using scan tool.
3) Start engine and run it for 1 min. or more.
4) Check DTC. 6
CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors fo rm ECM, BCM and ABS/ESP®
control modules.
3) Check CAN communication circuit for open, short or high resistance.
• Between ECM and ABS/ESP ® control module
• Between ECM and BCM
Is each CAN communication circuit in good condition? Go to Step 7. Repair circuit.
7 DTC check in ECM

control module with ignition switch turned.
2) Check ECM for DTC.
Does ECM communicate with control module other than
BCM (i.e. DTC P1676 and/or DTC P1685 are not detected)? Substitute a known-
good BCM and recheck.
Substitute a known-
good ECM and recheck.

(Bus Off Error)”.
Go to Step 3.
3 ECM and ABS/ESP ® control module connector check
1) Check for proper connection at each ECM and ABS/ ESP® control module connector terminals with ignition
switch turned OFF.
2) If connections are OK, recheck ECM for DTC with engine running.
Is there DTC P1685? Go to Step 4.
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
4 DTC check of ABS/ESP ® control module
1) Check DTC U1073 in ABS/ESP ® control module.
Is it indicated? Go to “DTC U1073:
Control Module
Communication Bus Off
in Section 4E” (Non-
ESP®
model) or “DTC
U1073: Control Module
Communication Bus Off
in Section 4F” (ESP ®
module). Go to Step 5.
5 CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connector s form ECM and ABS/ESP ®
control module.
3) Check CAN communication circuit between ECM and ABS/ESP ® control module for open, short or high
resistance.
Is each CAN communication circuit in good condition? Go to Step 6.
Repair circuit.
6 DTC check in ECM
1) Connect connectors to ECM and ABS/ESP ® control
module with ignition switch turned.
2) Check ECM for DTC.
Does ECM communicate with control module other than
ABS/ESP
® control module (i.e. DTC P1676 and/or DTC
P1678 are not detected)? Substitute a known-
good ABS/ESP
®
control module and
recheck. Substitute a known-
good ECM and recheck.

ABS Warning Light Does Not Come ON at Ignition Switch ONS7RS0B4504008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS contro l module through lamp driver module in
combination meter.
If the antilock brake system is in good condition, ABS control module turns ABS warning light ON at the ignition switch
ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS warning light is
turned ON continuously by ABS control module. Also, it is turned ON continuously by la mp driver module when the
connector of ABS control module is disconnected.
