Eps warning light circuit
Description If the power steering ecu detects a malfunction, the p/s warning light comes on. At this time, the power steering ecu stores a dtc in its memory. Wiring diagram Inspection procedure Check for dtc Using the intelligent tester (with can vim), check for dtcs and confir ...

Check for intermittent problems
Hint: Inspect the vehicle's ecm using check mode. Intermittent problems are easier to detect with the intelligent tester when the ecm is in check mode. In check mode, the ecm uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detec ...

Low battery positive voltage
Description When there is an abnormality in the power supply circuit of the brake actuator (skid control ecu), the skid control ecu sets a dtc and the operation is prohibited by the fail-safe function. This dtc is set when the voltage supplied to terminal ig1 is outside the dtc detection ...
