Transmission Control Switch Circuit (to 12/2010)

U660E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: Transmission Control Switch Circuit
- Transmission Control Switch Circuit

DESCRIPTION

When moving the shift lever into the S position using the transmission control switch, it is possible to switch the shift range position between "1" (first range) and "6" (sixth range).

Shifting up "+" once raises one shift range position, and shifting down "-" lowers one shift range position.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (BATTERY - TRANSMISSION CONTROL SWITCH)

(a) Disconnect the transmission control switch connector of shift lever assembly.





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

Standard voltage:





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

2. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BODY GROUND)

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





Standard resistance:





*1: w/ Smart Key System

*2: w/o Smart Key System

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

3. INSPECT TRANSMISSION CONTROL SWITCH

(a) Measure the resistance between each terminal of the shift lever assembly when the shift lever is moved to each position.





Standard resistance:





*1: w/ Smart Key System

*2: w/o Smart Key System

NG -- REPLACE TRANSMISSION CONTROL SWITCH Removal (to 12/2010)
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)

(a) Connect the transmission control switch connector of the shift lever assembly.





(b) Disconnect the ECM connector.

(c) Turn the ignition switch on (IG), and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

Standard voltage:





(d) Turn the ignition switch off.

(e) Disconnect the ECM connector.

(f) Measure the resistance according to the value(s) in the table below when the shift lever 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
