Satellite Switch Circuit: Procedure
WARNING: This page is about a different car, the 2009 Lexus IS 350 and 2009 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT SATELLITE SWITCH
- Disconnect the connector from the satellite switch.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
Tester Connection Condition Specified Condition J16-2 (LSFT) - J16-5 (E) Satellite switch LH is pressed Below 1 Ω J16-2 (LSFT) - J16-5 (E) Satellite switch LH is not pressed 10 kΩ or higher J16-3 (SET) - J16-5 (E) Satellite switch ON/OFF is pressed Below 1 Ω J16-3 (SET) - J16-5 (E) Satellite switch ON/OFF is not pressed 10 kΩ or higher J16-4 (RSEL) - J16-5 (E) Satellite switch RH is pressed Below 1 Ω J16-4 (RSEL) - J16-5 (E) Satellite switch RH is not pressed Below 1 Ω
NG → REPLACE SATELLITE SWITCH
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (COMBINATION METER - SATELLITE SWITCH)
- Disconnect the J35 and J16 connectors.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
Tester Connection Condition Specified Condition J35-5 (RSEL) - J16-4 (RSEL) Always Below 1 Ω J35-6 (LSEL) - J16-2 (LSFT) Always Below 1 Ω J35-7 (SET) - J16-3 (SET) Always Below 1 Ω J16-2 (LSFT) - Body ground Always 10 kΩ or higher J16-3 (SET) - Body ground Always 10 kΩ or higher J16-4 (RSEL) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → REPLACE COMBINATION METER ASSEMBLY
