DTC Troubleshooting
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check”.
2 Check transmission fluid temperature circuit for open
1) Turn ignition switch OFF.
2) Disconnect TCM connectors from TCM.
3) Check for proper connection to transmission fluid
temperature sensor at terminals “G08-5” and “G08-14”.
4) If OK, check continuity between terminals “G08-5” and
“G08-14” of disconnected harness side TCM connector.
Is continuity indicated?
Go to Step 3. “BLU/ORN” or “LT GRN”
circuit open.
3 Check transmission fluid temperature circuit for ground
short
1) Check continuity between terminal “G08-5” of
disconnected harness side TCM connector and ground.
Is continuity indicated?
“BLU/ORN” circuit
shorted to ground. Go to Step 4.
4 Check transmission fluid temperature circuit for IG
short
1) Cool down A/T fluid temperature under ambient
temperature.
2) Connect TCM connectors to TCM with ignition switch
OFF.
3) Turn ignition switch ON.
4) Measure voltage between terminal “G08-5” of TCM
connector and ground.
Is it 4.6 V or more?
“BLU/ORN” circuit
shorted to power circuit.
If circuit is OK, go to
Step 5. Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.
5 Inspect transmission fluid temperature sensor
1) Inspect transmission temperature sensor referring to
“Transmission Fluid Temperature Sensor Inspection”.
Is result satisfactory?
Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck. Replace transmission
fluid temperature
sensor.
