Pinout Values and Diagnostic Parameters

K41B CVT: CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: TERMINALS OF ECM

1. ECM





HINT
Each ECM terminal's standard voltage and resistance is shown in the table below.

In the table, first follow the information under "Condition". Look under "Terminal No. (Symbol) " for the terminals to be inspected. The standard voltage and resistance between the terminals is shown under "Specific Condition".

Use the illustration above as a reference for the ECM terminals.









(a) Waveform 1 (Reference)









(b) Waveform 2 (Reference)









(c) Waveform 3









HINT
Duty ratio increases with downshifts.

(d) Waveform 4









HINT
Duty ratio increases with upshifts.

(e) Waveform 5









HINT
Duty ratio increases to 100% with the lock up ON.

(f) Waveform 6









HINT
The wavelength shortens and the voltage increases as the primary pulley speed increases.

(g) Waveform 7









HINT
The wavelength shortens as the turbine speed increases.

(h) Waveform 8









HINT
The wavelength shortens as the secondary pulley speed increases.
