ADJUSTMENT
HINT:
• On the RH side, use the same procedures as on the LH
side.
• Since a centering bolt is used as door hinge mounting
bolts on the body side and the door side, the door cannot
be adjusted with them on. Substitute a bolt with a washer
for the centering bolt.
1. INSPECT BACK DOOR PANEL SUB-ASSEMBLY
(a) Check that the clearance is within the standard
range.

CHECK FOR INTERMITTENT
PROBLEMS
1. CHECK FOR INTERMITTENT PROBLEMS
HINT:
For use of the intelligent tester only:
Inspect the vehicle's ECM using check mode.
Intermittent problems are easier to detect with an
intelligent tester when the ECM is in check mode. In
check mode, the ECM uses 1 trip detection logic, which
is more sensitive to malfunctions than normal mode
(default), which uses 2 trip detection logic.
(a) Clear the DTCs (See page ES-39).
(b) Switch the ECM from normal mode to check mode
using an intelligent tester (See page ES-43).
(c) Perform a simulation test (See page IN-35).
(d) Check and wiggle the harness(es), connector(s)
and terminal(s) (See page IN-30).

BASIC INSPECTION
When a malfunction is not confirmed by the DTC check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly and efficiently. Therefore, using this check is essential
when engine troubleshooting.
NOTICE:
Carry out this check with the engine stopped and ignition
switch off.
