Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - A750F AUTOMATIC TRANSMISSION / TRANSAXLE
INSPECT TRANSMISSION CONTROL SWITCH
CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BATTERY, BODY GROUND)
CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)
AUTOMATIC TRANSMISSION SYSTEM (for 1GR-FE) - Transmission Control Switch Circuit
DESCRIPTION
When moving the shift lever to S using the transmission control switch, it is possible to switch the shift range between "1" (1st range) and "5" (5th range).
Shifting to "+" once raises the shift range by one, and shifting to "-" lowers the shift range by one.

INSPECTION PROCEDURE
1.INSPECT TRANSMISSION CONTROL SWITCH |

Disconnect the transmission control switch connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition 3 (IG) - 7 (S) Shift lever in S, "+" or "-" Below 1 Ω 2 (SFTU) - 5 (E) Shift lever held in "+"
(Up-shift)Below 1 Ω 1 (SFTD) - 5 (E) Shift lever held in "-"
(Down-shift)Below 1 Ω 3 (IG) - 7 (S) Shift lever not in S, "+" or "-" 10 kΩ or higher 2 (SFTU) - 5 (E) Shift lever in S 10 kΩ or higher 1 (SFTD) - 5 (E) Shift lever in S 10 kΩ or higher

OK | |
2.CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BATTERY, BODY GROUND) |

Disconnect the transmission control switch connector.
Turn the engine switch on (IG).
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Condition Specified Condition E52-3 (IG) - Body ground Engine switch on (IG) 11 to 14 V E52-3 (IG) - Body ground Engine switch off Below 1 V
Turn the engine switch off.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition E52-5 (E) - Body ground Always Below 1 Ω

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

Disconnect the ECM connector.
Turn the engine switch on (IG).
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Condition Specified Condition A38-25 (S) - Body ground Engine switch on (IG)Shift lever in S, "+" or "-"11 to 14 V A38-25 (S) - Body ground Engine switch on (IG)Shift lever not in S, "+" or "-"Below 1 V
Turn the engine switch off.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition A38-38 (SFTU) - Body ground Shift lever held in "+"
(Up-shift)Below 1 Ω A38-27 (SFTD) - Body ground Shift lever held in "-"
(Down-shift)Below 1 Ω A38-38 (SFTU) - Body ground Shift lever in S 10 kΩ or higher A38-27 (SFTD) - Body ground Shift lever in S 10 kΩ or higher
