DESCRIPTION
Shifting from 1st to 5th is performed in combination with "ON" and "OFF"
operation of the shift solenoid
valves SL1, SL2, SL3, S4 and SR which are controlled by the ECM. If an open or
short circuit occurs in
either of the shift solenoid valves, the ECM controls the remaining normal shift
solenoid valves to allow
the vehicle to be operated smoothly (Fail safe function).
MONITOR DESCRIPTION
The ECM 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 ECM detects the problem and illuminates the MIL and stores the DTC. And the ECM performs the fail-safe function and turns the other normal shift solenoid valves "ON/OFF" (In case of an open or short circuit, the ECM stops sending current to the circuit.) (See page AX-30).

INSPECTION PROCEDURE
1 INSPECT TRANSMISSION WIRE (SR)
(a) Disconnect the transmission wire connector from the transaxle.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
2 CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)
(a) Connect the transmission wire connector to the transaxle.
(b) Disconnect the connector from the ECM.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
REPLACE ECM
3 INSPECT SHIFT SOLENOID VALVE SR
(a) Remove the shift solenoid valve SR.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) Connect the positive (+) lead to the terminal of the solenoid connector, and the negative (-) lead to the solenoid body.
OK: The solenoid makes an operating sound.
REPAIR OR REPLACE TRANSMISSION WIRE
Installation
1. INSTALL CRANKSHAFT POSITION SENSOR
Apply a light coat of engine oil to the O-ring on the
crankshaft position sensor.
Install the crankshaft position sensor with the bolt.
