Engine General Information and Diagnosis: 1A-174
9
DTC check in ECM
1) Disconnect connector from keyless start control module
(if equipped) with ignition switch turned OFF.
2) Check ECM for DTC.
Is there DTC P1674?
Go to Step 10.
“G44-19” or “G44-18”
circuit wire between
keyless start control
module and CAN circuit
junction connector is
open or high resistance.
If wires are OK,
substitute a known-
good keyless start
control module and
recheck.
10
DTC check in ECM
1) Disconnect connector from combination meter with
ignition switch turned OFF.
2) Check ECM for DTC.
Is there DTC P1674?
Go to Step 11.
“G28-10” or “G28-8”
circuit wire between
combination meter and
CAN circuit junction
connector is open or
high resistance. If wires
are OK, substitute a
known-good
combination meter or
keyless start control
module (if equipped)
and recheck.
11
DTC check in ECM
1) Disconnect connector from 4WD control module (for J20
engine) with ignition switch turned OFF.
2) Check ECM for DTC.
Is there DTC P1674?
Go to Step 12.
“E91-22” or “E91-23”
circuit wire between
4WD control module
and CAN circuit junction
connector is open or
high resistance. If wires
are OK, substitute a
known-good 4WD
control module and
recheck.
12
ABS hydraulic unit / control module check
1) Measure resistance at following connector terminals.
• Between “E03-8” terminal and “E03-6” terminal of
ABS hydraulic unit / control module connector.
• Between “E03-10” terminal and “E03-12” terminal of
ABS hydraulic unit / control module connector.
Is measured resistance below 1
Ω
?
Go to Step 13.
Substitute a known-
good ABS hydraulic unit
/ control module and
recheck.
13
CAN communication line circuit insulation check
1) Disconnect connector from ABS hydraulic unit / control
module assembly with ignition switch turned OFF.
2) Measure resistance between “E03-6” and “E03-12”
terminals of ABS hydraulic unit / control module
connector.
Is resistance infinity?
Go to Step 14.
Repair insulation of
CAN communication
line circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
14
CAN communication line circuit insulation check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between “E23-4” and “E23-19”
terminals of ECM connector.
Is resistance infinity?
Go to Step 15.
Repair insulation of
CAN communication
line circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
