Description
When the power supply to the TCM is cut off, for example because the battery is removed, and the self-diagnosis memory function stops, a malfunction is detected.
NOTE: Since "P1701" is indicated when replacing TCM, perform diagnosis after erasing "Self Diagnostic Results".

DTC CONFIRMATION PROCEDURE
NOTE: Immediately after performing any "DTC CONFIRMATION PROCEDURE", always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT
Turn ignition switch ON.
Wait for at least 2 consecutive seconds.
Perform "Self Diagnostic Results" in "TRANSMISSION".
Diagnosis Procedure
Regarding Wiring Diagram information, refer to TM-126, "Wiring Diagram".
1.CHECK TCM POWER SOURCE
Turn ignition switch OFF.
Disconnect TCM connector.
Check voltage between TCM vehicle side harness connector terminals.
2.CHECK TCM GROUND CIRCUIT
Turn ignition switch OFF.
Check continuity between TCM vehicle side harness connector terminals and ground.
3.CHECK TCM POWER CIRCUIT
Check voltage between TCM vehicle side harness connector terminals and ground.
4.CHECK HARNESS BETWEEN TCM AND IPDM E/R AND BETWEEN TCM AND BATTERY (PART 1)
Turn ignition switch OFF.
Disconnect IPDM E/R connector.
Check continuity between TCM vehicle side harness connector terminals and IPDM E/R vehicle side harness connector terminal.
4. Disconnect fuse block (J/B) connector.
5. Check continuity between TCM vehicle side harness connector terminals and fuse block (J/B) vehicle side harness connector terminal.
5.CHECK HARNESS BETWEEN TCM AND IPDM E/R AND BETWEEN TCM AND BATTERY (PART 2)
Check continuity between TCM vehicle side harness connector terminals and ground.
6.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
