DIAGNOSTIC PROCEDURE FOR NO-DIAGNOSTIC TROUBLE CODE (DTC)
Step
26 CHECK "P" RANGE INDICATOR LIGHT
BULB.
1) Turn ignition switch to OFF.
2) Remove combination meter.
3) Remove "P" range indicator light bulb from
combination meter.
Is "P" range indicator light bulb OK?
27 CHECK HARNESS CONNECTOR BETWEEN
TCM AND COMBINATION METER.
1) Disconnect connectors from TCM and com-
bination meter.
2) Measure resistance of harness between
TCM and combination meter.
Connector & terminal
Except 3.0 L model and TURBO model:
(B55) No. 1 — (i11) No. 1:
3.0 L model and TURBO model:
(B55) No. 1 — (i10) No. 14:
Does the measured value exceed the spec-
ified value?
28 CHECK HARNESS CONNECTOR BETWEEN
TCM AND INHIBITOR SWITCH.
1) Turn ignition switch to OFF.
2) Disconnect connectors from TCM, inhibitor
switch and combination meter.
3) Measure resistance of harness between
TCM and chassis ground.
Connector & terminal
(B55) No. 1 — Chassis ground:
Does the measured value exceed the spec-
ified value?
29 CHECK HARNESS CONNECTOR BETWEEN
TCM AND INHIBITOR SWITCH.
1) Turn ignition switch to OFF.
2) Disconnect connectors from TCM and
inhibitor switch.
3) Measure resistance of harness between
TCM and inhibitor switch connector.
Connector & terminal
(B55) No. 3 — (T7) No. 8:
Is the measured value less than the speci-
fied value?
30 CHECK INPUT SIGNAL FOR TCM.
1) Turn ignition switch to OFF.
2) Connect connector to TCM and inhibitor
switch.
3) Turn ignition switch to ON.
4) Move select lever to R range.
5) Measure voltage between TCM and chas-
sis ground.
Connector & terminal
(B55) No. 3 (+) — Chassis ground (–):
Is the measured value less than the speci-
fied value?

Go to step 27. Replace "P" range
indicator light bulb.
<Ref. to IDI-14,
Combination
Meter Assembly.>
Go to step 65. Repair open circuit
in harness
between inhibitor
switch connector
and combination
meter, and poor
contact in cou-
pling connector.
Go to step 29. Repair ground
short circuit in "P"
range circuit.
Go to step 30. Repair open circuit
in harness
between TCM and
inhibitor switch
connector, and
poor contact in
coupling connec-
tor.
Go to step 31. Go to step 65.
