PROBLEM SYMPTOMS TABLE
HINT:
If a normal code is displayed during the diagnostic trouble code check although the trouble still occurs, check
the electrical circuits for each symptom in the order given in the charts on the following pages and proceed
to the page given for troubleshooting.
The Matrix Chart is divided into 2 chapters.
1. Chapter 1: Electronic Circuit Matrix Chart
S Refer to the table below when the trouble cause is considered to be electrical.
S If the instruction ”Proceed to next circuit inspection shown on matrix chart” is given in the flow chart
of each circuit, proceed to the circuit with the next highest number in the table to continue the check.
S If the trouble still occurs even though there are no abnormalities in any of the other circuits, check and
replace the ECM.
HINT:

MONITOR DRIVE PATTERN
1. MONITOR DRIVE PATTERN FOR ECT TEST
(a) Perform this drive pattern as one method to simulate the detection conditions of the ECT malfunctions.
(The DTCs may not be detected due the actual driving conditions. And some codes may not be de-
tected through this drive pattern).
HINT:
Preparation for driving
SWarm up the engine sufficiently. (Engine coolant temperature is 60˚C(140˚F) or higher)
SDrive the vehicle when the atmospheric temperature is−10˚C(14˚F) or higher. (Malfunction is not
detected when the atmospheric temperature is−10˚C(14˚F) or less)
Driving note
SDrive the vehicle through all gears.
Stop
1st
2nd
3rd
4th
5th
5th (lock−up ON).
SPerform engine brake test in the S position.
While driving in the 5(S) position and 5th gear lock−up, shift into the ”−” position and down−shift from
5th to 4th, 4th to 3rd, 3rd to 2nd, 2nd to1st.
Check that the engine brake performs properly whenever down−shift takes place.
SRepeat the above driving pattern three times or more.
NOTICE:
SWhen using the hand−held tester, monitor status can be found in the ”DIAGNOSIS / OBD/MOBD
/ DATA LIST”.
SIn the event that the drive pattern must be interrupted (possibly due to traffic conditions or other
factors) the drive pattern can be resumed and, in most cases, the monitor can be completed.
CAUTION:
Perform this drive pattern on a level road as much as possible and strictly observe the posted speed
limits and traffic laws while driving.
