control relay.
3CHECK HARNESS BETWEEN ECM AND
ELECTRONIC THROTTLE CONTROL RE-
LAY.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from ECM.
3) Measure the resistance between ECM con-
nector and chassis ground.
Connector & terminal
(B136) No. 21 — Chassis ground:

MΩ?
Repair poor con-
tact in ECM con-
nector. Replace
the ECM if defec-
tive. FU(H6DO)-32,

3CHECK FUSE (No. 32).
1) Turn the ignition switch to OFF.
2) Remove the fuse.
Is the fuse (No. 32) blown out? Replace the fuse
(No. 32). If the
replaced fuse (No.
32) has blown out
easily, repair the
short circuit of har-
ness between fuse
(No. 32) and TCM.
Go to step 4.
4CHECK HARNESS CONNECTOR BETWEEN
TCM AND ECM.

Is the resistance less than 1
Ω?
Go to step 5.Repair the open
circuit of harness
between TCM and
transmission con-
nector, or poor
contact of connec-
tor.
5CHECK HARNESS CONNECTOR BETWEEN
TCM AND ECM.
Measure the resistance of harness between
TCM connector and chassis ground.
Connector & terminal
(B55) No. 19 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 6.Repair the short
circuit of harness
between transmis-
sion connector
and chassis
ground.
6CHECK TCM OUTPUT SIGNAL.
1) Connect the TCM and ECM connector.
2) Turn the ignition switch to ON. (Engine
OFF)
3) Shift the select lever to shift to the “P”
range.
4) Measure the voltage between TCM con-
nector and chassis ground.
Connector & terminal
(B55) No. 19 (+) — Chassis ground (–):
Is the voltage less than 1 V? Go to step 7.Replace the TCM.
Tr a n s m i s s i o n C o n -
trol Module
(TCM).>
7CHECK TCM OUTPUT SIGNAL.
1) Shift the select lever to “D” range.
2) Measure the voltage between TCM con-
nector and chassis ground.
Connector & terminal
(B55) No. 19 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 8.Replace the TCM.
Tr a n s m i s s i o n C o n -
trol Module
(TCM).>
8CHECK POOR CONTACT.Is there any open or poor con-
tact of connector (loosing ter-
minal, entering foreign matter,
damaging connector body)?
Repair the poor
contact.
Check the neutral
switch of ECM.
Step Check Yes No
