Pinout Values and Diagnostic Parameters

CRUISE CONTROL: CRUISE CONTROL SYSTEM: TERMINALS OF ECM

1. CHECK ECM (for 1GR-FE)





(a) Disconnect the B38, F50 and F51 ECM connectors.

(b) Measure the voltage and resistance according to the value(s) in the table below.





If the result is not as specified, there may be a malfunction on the wire harness side.

(c) Reconnect the B38, F50 and F51 ECM connectors.

(d) Measure the voltage according to the value(s) in the table below.





If the result is not as specified, the ECM may be malfunctioning.

2. CHECK ECM (for 2TR-FE)





(a) Disconnect the B39, F50 and F51 ECM connectors.

(b) Measure the voltage and resistance according to the value(s) in the table below.





If the result is not as specified, there may be a malfunction on the wire harness side.

(c) Reconnect the B39, F50 and F51 ECM connectors.

(d) Measure the voltage according to the value(s) in the table below.
