1A-175 Engine General Information and Diagnosis:
15
CAN communication line circuit continuity check
1) Measure resistance at following connector terminals.
• Between “E23-4” terminal of ECM connector and
“E03-10” terminal of ABS hydraulic unit / control
module connector
• Between “E23-19” terminal of ECM connector and
“E03-8” terminal of ABS hydraulic unit / control
module connector
• Between “E03-12” terminal of ABS hydraulic unit /
control module connector and each “G31-1” terminal
of BCM connector, “E91-22” terminal of 4WD control
module connector (for J20 engine), “E92-17” terminal
of TCM connector (for A/T model), “G44-19” terminal
of keyless start control module connector (if
equipped), “G28-10” terminal of combination meter
connector
• Between “E03-6” terminal of ABS hydraulic unit /
control module connector and each “G31-3” terminal
of BCM connector, “E91-23” terminal of 4WD control
module connector (for J20 engine), “E92-7” terminal
of TCM connector (for A/T model), “G44-18” terminal
of keyless start control module connector (if
equipped), “G28-8” terminal of combination meter
connector
• Between “G31-2” terminal of BCM connector and
“RED” wire terminal of DLC
• Between “G31-4” terminal of BCM connector and
“WHT” wire terminal of DLC
Is each resistance below 1
Ω
?
Go to Step 16.
Repair open or high
resistance of CAN
communication line
circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
16
CAN communication line circuit ground short check
1) Measure resistance at following connector terminals.
• Between “E23-4” terminal of ECM connector and
vehicle body ground
• Between “E23-19” terminal of ECM connector and
vehicle body ground
• Between “E03-12” terminal of ABS hydraulic unit /
control module connector and vehicle body ground
• Between “E03-6” terminal of ABS hydraulic unit /
control module connector and vehicle body ground
• Between “G31-2” terminal of BCM connector and
vehicle body ground
• Between “G31-4” terminal of BCM connector and
vehicle body ground
Is each resistance infinity?
Go to Step 17.
Repair short to ground
of CAN communication
line circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
