Shift Paddle Switch Circuit

AA80E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: Shift Paddle Switch Circuit
- Shift Paddle Switch Circuit

DESCRIPTION

When the shift lever is in D, operating the "-" side shift paddle switch will cause the transmission to enter fixed range mode which restricts the highest gear. By operating the shift paddle switches "+" (UP) or "-" (DOWN), the shift range can be changed.

When the vehicle is being operated in D position (fixed range mode), if the vehicle is stopped or the accelerator pedal is kept steady for a certain period of time with the transmission in the same gear, the vehicle will change back automatically to normal D position operation.

When the shift lever is in M, it is possible to make use of the highest engine speeds by holding the vehicle in a gear. Gear hold control means that gear shifts will not be performed as long as the paddle switches are not operated in either the "+" (UP), or "-" (DOWN) direction.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - BODY GROUND)

(a) Disconnect the steering pad switch connector and spiral cable connector.





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

Standard Resistance:





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

2. INSPECT SPIRAL CABLE SUB-ASSEMBLY

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





Standard Resistance:





NG -- REPLACE SPIRAL CABLE SUB-ASSEMBLY
OK -- Continue to next step.

3. INSPECT TRANSMISSION SHIFT SWITCH ASSEMBLY

(a) Disconnect the switch wire connector from the transmission shift switch.





(b) Measure the resistance between each terminal when the paddle shift is moved to each position.

Standard Resistance:





NG -- REPLACE TRANSMISSION SHIFT SWITCH ASSEMBLY
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - TRANSMISSION SHIFT SWITCH)

(a) Connect the switch wire connector to the transmission shift switch.





(b) Measure the resistance between each terminal when the paddle shift is moved to each position.

Standard Resistance:





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

5. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - ECM)

(a) Connect the spiral cable connector and steering pad switch connector.





(b) Disconnect the ECM connector.

(c) Disconnect the transmission control switch connector.

(d) Measure the resistance according to the value(s) in the table below when the paddle shift is moved to each position.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE Symptom Related Diagnostic Procedures
