Transmission Control Switch Circuit
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 the 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:
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:
NG -- REPLACE TRANSMISSION CONTROL SWITCH
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 A10 ECM connector.
(c) Turn the engine 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 engine 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
