6)”.

contacts.
If OK, then check the diff-lock relay insulation and
continuity.
Refer to “2WD/4WD/Diff-lock System Inspection in
Section 3B (Page 3B-17)”.
Is the diff-lock relay OK?
• Inspect the 4WD/diff-
lock switch.
• Y/B wire open or
shorted to ground, or
poor “21” connection.
• If wire and
connection are OK,
intermittent trouble or
faulty ECM.
• Recheck each
terminal and wire
harness for open
circuit and poor
connection.
• Replace the ECM
with a known good
one, and inspect it
again.
Replace the diff-lock
relay with a new one.
