522399.03 — Transmission Clutch K1 Solenoid Short to Power
Transmission Clutch K1 Solenoid Short to Power Diagnostic Procedure
Alarm Level:
No Warning Lamp
1 Intermittent Check
Action: Does diagnostic trouble code (DTC) periodically “go away”?
Result:
YES: DTC is intermittent. See Intermittent Diagnostic Trouble Code (DTC) Diagnostics . (Group 9015-15.)
NO: Go to Short Circuit Check—Solenoid Circuits.
2 Short Circuit Check—Solenoid Circuits
Action:
Ignition OFF.
Disconnect transmission harness-to-transmission control valve harness connector (X36). See Transmission Harness (W10) Component Location . (Group 9015-10.)
Check for resistance between pin 3 (circuit T05 BLU) on transmission control valve harness side of connector (X36) and all other pins on connector (X36).
Is resistance with any wire less than 5 ohms?
Result:
YES: Circuit T05 BLU is short to wire with resistance less than 5 ohms. Replace transmission control valve harness. See Transmission Hydraulic Control Valve Disassemble and Assemble .
(Group 0360.)
NO: Go to Short Circuit Check—Short to Power.
3 Short Circuit Check—Short to Power
Action:
Ignition OFF.
