AUTOMATIC TRANSMISSION (DIAGNOSTICS)
W: DTC P1707 AT AWD SOLENOID VALVE CIRCUIT MALFUNCTION
DTC DETECTING CONDITION:
Output signal circuit of transfer duty solenoid is open or shorted.
TROUBLE SYMPTOM:
• Tight corner braking phenomenon is occurred.
• Front wheel slips on the slippery road.
WIRING DIAGRAM:
Step
1 CHECK HARNESS CONNECTOR BETWEEN
TCM AND TRANSMISSION.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from TCM and
transmission.
3) Measure the resistance of the harness
between TCM connector and transmission
connector.

2 CHECK HARNESS CONNECTOR BETWEEN
TCM AND TRANSMISSION.
Measure the resistance of harness connector
between TCM and chassis ground.
Connector & terminal
(B55) No. 4 — Chassis ground:
3 CHECK TRANSFER DUTY SOLENOID.
