PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the DTC check but the trouble still occurs, check the circuits for each
symptom in the order given in the charts on the following pages and proceed to the page given for trouble-
shooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On±vehicle Repair Matrix Chart
Chapter 3: Off±vehicle repair Matrix Chart
If the instruction ºProceed to next circuit inspection shown on matrix chartº is given in the flow
chart for each circuit, proceed to the circuit with the next highest number in the table to continue
the check.
If the trouble still occurs even though there are no abnormalities in any of the other circuits, then
check and replace the ECM.

INSPECTION PROCEDURE
1 Check operation of speedometer.
CHECK:
Drive the vehicle and check if the operation of the speedmeter in the combination meter is normal.
HINT:
The vehicle speed sensor is operating normally if the speedometer display is normal.
NG Check speedometer circuit. See combination
meter troubleshooting (See page BE±47).
OK
2 Check voltage between terminal SPD of ECM connector and body ground.
PREPARATION:
(a) Remove glove compartment (See page BO±75).
(b) Shift the shift lever to neutral.
(c) Jack up one of the front wheels.
(d) Turn ignition switch ON.
CHECK:
Measure voltage between terminal SPD of ECM connector and
body ground when the wheel is turned slowly.
OK:
Voltage is generated intermittently.
NG Check and repair harness and connector
between combination meter and ECM
(See page IN±31).
OK

connector.
PREPARATION:
Disconnect the solenoid connector from the automatic trans-
axle.
CHECK:
Check the harness and connector between terminal S1 or S2
of ECM and terminal S1 or S2 of solenoid connector.
OK:
There is no open and no short circuit.
