Cruise Control System

DTC P0607 Control Module Performance

CIRCUIT DESCRIPTION

Dtc Detection Condition:




When the brake pedal is depressed, the stop light switch sends a signal to the ECM. When the ECM receives this signal, it cancels the cruise control.

A fail-safe function is provided so that the cancel functions normally, even if there is a malfunction in the stop light signal circuit.

The cancel conditions are: Battery positive voltage at terminal STP-

When the brake is depressed, battery positive voltage normally applies through the STOP fuse and stop light switch to terminal STP- of the ECM, and the ECM turns the cruise control off.

If the harness connected to terminal STP- has an open circuit, terminal STP- will have battery voltage and the cruise control will be turned off.
