3
Check engine coolant temperature signal circuit for IG
short
1) Turn ignition switch OFF.
2) Disconnect TCM and ECM connectors from TCM and
ECM.
3) Check proper connection to TCM at terminal “G07-7”
and to ECM at terminal “G04-8”.
4) If OK, turn ignition switch ON and measure voltage
between terminal “G07-7” of disconnected harness side
TCM connector and ground.
Is it 10 – 14 V?
“GRY/BLK” circuit
shorted to power circuit.
Go to Step 4.
4
Check engine coolant temperature signal circuit for
open
1) Turn ignition switch OFF.
2) Check continuity between terminal “G07-7” of
disconnected harness side TCM connector and terminal
“G04-8” of disconnected harness side ECM connector.
Is continuity indicated?
Go to Step 5.
“GRY/BLK” circuit open.
5
Check engine coolant temperature signal circuit for
ground short
1) Check continuity between terminal “G07-7” of
disconnected harness side TCM connector and ground.
Is continuity indicated?
“GRY/BLK” circuit
shorted to ground.
Go to Step 6.
6
Inspect engine coolant temperature sensor
1) Inspect engine coolant temperature sensor referring to
“Engine Coolant Temperature (ECT) Sensor Inspection
in Section 1C”.
Is inspection result OK?
Intermittent trouble or
faulty TCM or ECM.
