Inspection Procedure

  1. INSPECT TRANSMISSION CONTROL SWITCH 
    1. Disconnect the L42 transmission control switch connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION

      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
