communicating by means of CAN.
2) Check DTC for ESP
®.
Is DTC U1101 detected?
Go to Step 5.
Check for intermittent
trouble referring to
“Intermittent and Poor
Connection Inspection
in Section 00 in related
manual”.
5
CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of ESP
® control module and
TCM communicating by means of CAN.
Is each CAN communication circuit between ESP
®
control
module and TCM opened, shorted or high resistance?
Repair or replace the
CAN communication
line.
Go to Step 6.
6
CAN communication circuit check
1) Disconnect connectors of all control modules
communicating by means of CAN.
Is each CAN communication circuit between disconnected
control modules (other than ESP
®
control module and TCM)
opened, shorted or high resistance?
Go to Step 7.
Repair or replace the
CAN communication
line.
7
DTC check for ESP
®
1) Connect connectors of disconnected control modules
communicating by means of CAN.
2) Disconnect each connector.
• ECM
• TCM
• BCM
• 4WD control module (if equipped)
• Keyless start control module (if equipped)
• Steering angle sensor
3) Check DTC for ESP
®.
Is DTC U1101 detected?
Check ESP
® control
module power and
ground circuit. If circuits
are OK, substitute a
known-good ESP
®
hydraulic unit / control
module assembly and
recheck.
Check applicable
control module power
and ground circuit. If
circuit is OK, substitute
a known-good
applicable control
module and recheck.
