4E-18 ABS:
Inspection
Step
1 1) Turn ignition switch to ON position.
Does ABS warning light come ON?
2 1) Turn ignition switch to OFF position.
Are main fuses for ABS pump motor and ABS solenoid in
good condition?
3 1) Disconnect ABS hydraulic unit / control module
connector.
2) Check for proper connection to ABS hydraulic unit /
control module connector at terminal "E03-7".
3) If OK then turn ignition switch to ON position and
measure voltage between terminal "E03-7" and vehicle
body ground.
Is it 10 – 14 V?
4 1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS hydraulic unit /
control module connector at terminals "E03-1" and "E03-
14".
3) If OK then turn ignition switch to ON position and
measure voltage between each terminal of "E03-1",
"E03-14" and vehicle body ground.
Are they 10 – 14 V?
5 1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS hydraulic unit /
control module connector at terminals "E03-13" and
"E03-26".
3) If OK, measure resistance between each terminal of
"E03-13", "E03-26" and vehicle body ground.
Are resistance less than 2
6 1) Check if communication is possible by trying
communication with other controller (ECM, TCM, BCM,
4WD control module or SDM).
Is it possible to communicate with other controller?
7 1) Turn ignition switch to ON position.
2) Measure voltage between terminal B of data link
connector and vehicle body ground.
Is voltage 10 – 12 V?
8 1) Turn ignition switch to OFF position.
2) Measure resistance between the following terminals;
• Terminal G of data link connector and vehicle body
ground.
• Terminal G1 of data link connector and vehicle body
ground.
Is each resistance 1
Action

No
Go to Step 6.
Replace fuse and check
for short.
"GRN/ORN" wire circuit
open.
"WHT/RED" and/or
"WHT/BLU" wire circuit
open.
Ground circuit for ABS
hydraulic unit / control
module open or high
resistance.
Repair open in common
section of serial data
circuit ("PPL/WHT" wire
circuit) used by all
controllers or short to
ground or power circuit
which has occurred
somewhere in serial
data circuit ("PPL/WHT"
wire circuit).
Terminal B circuit open
or shorted to ground.
Terminal G and/or G1
circuit open or high
resistance.
