Diag. Trouble Code 64 Shift Solenoid Valve SL Circuit
CIRCUIT DESCRIPTION
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic
pressure acting on the lock–up relay valve, which then controls operation of the lock–up clutch. If a
malfunction occurs in this circuit and diagnostic trouble code 64 is stored in memory, the O/D OFF
indicator light does not blink.
Fail Safe Function
If the ECM detects a malfunction, it turns the lock–up solenoid valve OFF.
Code No. Diag. Trouble Code Detection Condition
(a) Solenoid resistance is 8W or lower (short
circuit) when solenoid energized.
(b) Solenoid resistance is 100 kW or higher
(open circuit) when solenoid is not
energized.
ECM memorizes diag. trouble code 64 if above (a)
or (b) condition is detected once or more, but ECM
does not start O/D OFF indicator light blinking.
DIAGNOSTIC CHART DIAGNOSTIC CHART
Check shift solenoid valve SL.
Check harness and connector between
electronically controlled transaxle solenoid
connector and ECM.
Replace ECM.
