DESCRIPTION

Based upon a signal from the TCM, the combination of shift solenoid valves (S1, S2, S3, S4, SR, SL1, SL2) changes the gear position from 1st to 6th. As a fail-safe function, if the solenoid valve system is open or shorted, the TCM cuts power to all solenoids, leaving just the mechanical hydraulic circuit, requiring manual shifting.





Reference (Using an oscilloscope):

Check the waveform between the terminals SL2+ and SL2- of the TCM connector





Standard:

Refer to the illustration.





MONITOR DESCRIPTION

This DTC indicates an open or short in the shift solenoid valve SL2 circuit. The TCM commands gear shifts by turning the shift solenoid valves "ON/OFF". When there is an open or short circuit in any shift solenoid valve circuit, the TCM detects the problem and illuminates the MIL and stores the DTC.

INSPECTION PROCEDURE

NOTICE:
Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

HINT
* The shift solenoid valve SL2 is turned on/off normally when the shift lever is in the D position:






PROCEDURE

1. INSPECT TRANSMISSION WIRE (SL2)

(a) Disconnect the L4 transmission wire connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





(c) Connect the L4 transmission wire connector.

NG -- INSPECT SHIFT SOLENOID SL2 (TRANSMISSION VALVE BODY ASSEMBLY)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - TCM)

(a) Disconnect the TCM connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





(c) Connect the TCM connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. REPLACE TCM

(a) Replace the TCM Removal.

NEXT -- THE RESET MEMORY Programming and Relearning

4. INSPECT SHIFT SOLENOID SL2 (TRANSMISSION VALVE BODY ASSEMBLY) P0766

NG -- REPLACE TRANSMISSION VALVE BODY ASSEMBLY Removal

OK -- REPAIR OR REPLACE TRANSMISSION WIRE Removal
