## DTC P0562 Non-Europe or N. American Emissions

### Circuit Description

The transmission control module (TCM) is an electronic device which monitors inputs to control various transaxle functions including shift quality and transaxle sensors, switches, and components to process for use within the control program. Based on this input information, the TCM controls various transaxle output functions and devices.

### DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0562 System Voltage Low

### Conditions for Setting the DTC

• | System voltage is less than 8.5 volts.

• | Transaxle input voltage is too low.

• | Engine speed is greater than 500 RPM.

• | Immediately after the above condition occurs

### Action Taken When the DTC Sets

• | The hold lamp will blink.

• | The TCM will record operating conditions at the time the diagnostic fails. This information will be stored in the Failure Records buffer.

• | Adopt Emergency/ Substitute mode and constant 4th gear by hydraulic control.

• | After ignition OFF/ON : 3rd gear by hydraulic control. P, R and N also possible.

• | Power supply cut off to the pressure control solenoid valve.

### Conditions for Clearing the DTC

• | The hold lamp will turn OFF when the malfunction has not occurred after 3 ignition cycles.

• | A history DTC will clear after 40 consecutive warm-up cycles without a fault.

• | Using a scan tool can clear history DTCs.

### Diagnostic Aids

• | Inspect the poor wiring harness connection for TCM connectors and transaxle wiring connectors.

• | Inspect the improperly formed or damaged terminals.
