DESCRIPTION

Based upon a signal from the TCM, the combination of shift solenoid valve (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 SL1+ and SL1- of the TCM connector





Standard:

Refer to the illustration.





MONITOR DESCRIPTION

This DTC indicates an open or short in the shift solenoid valve SL1 circuit. The TCM commands gearshift 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 SL1 is turned on/off normally when the shift lever is in the D position:






PROCEDURE

1. INSPECT TRANSMISSION WIRE (SL1)

(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 VALVE SL1 (TRANSMISSION VALVE BODY ASSEMBLY)
OK -- Continue to next step.

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

(a) Disconnect the A18 TCM connector.

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

Standard resistance:





(c) Connect the A18 TCM connector.

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

3. REPLACE TCM

(a) Replace the TCM Removal.

NEXT -- PERFORM THE RESET MEMORY Programming and Relearning

4. INSPECT SHIFT SOLENOID VALVE SL1 (TRANSMISSION VALVE BODY ASSEMBLY)

(a) Remove the transmission valve body assembly Removal.

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









Standard Resistance:





(c) Connect the positive (+) lead with a 21 W bulb to terminal 1 and the negative (-) lead to terminal 2 of the shift solenoid valve connector, then check the movement of the valve.

OK:

The solenoid makes an operating sound.

NG -- REPLACE TRANSMISSION VALVE BODY ASSEMBLY Removal

OK -- REPAIR OR REPLACE TRANSMISSION WIRE Removal
