With Powertrain Control Module

Wiring Diagram:

CIRCUIT DESCRIPTION

Circuit 339 is the ignition voltage feed for the Powertrain Control Module (PCM). Circuit 440 is the battery feed for the PCM.

If the PCM detects either a low system voltage or a high system voltage for a short time, then DTC P0560 sets. DTC P0560 is a type D DTC.

CONDITIONS FOR SETTING THE DTC

System Voltage Low

^ The engine speed is greater than 1500 RPM.

^ One of the following conditions exists for greater than 15 seconds:

- The system voltage is less than 10.5 volts at a maximum transmission temperature of 152°C (305°F).

- The system voltage is less than 6.7 volts at a minimum transmission temperature of -40°C (-40°F).

System Voltage High

System voltage is greater than 19 volts for 10 seconds.

ACTION TAKEN WHEN THE DTC SETS

^ The PCM does not illuminate the Malfunction Indicator Lamp (MIL).

^ The PCM commands an immediate landing to second gear.

^ The PCM turns off the PC Sol. Valve.

^ The PCM inhibits the TCC engagement.

^ The PCM freezes the shift adapts.

^ DTC P0560 is stored in PCM history.

CONDTIONS FOR CLEARING THE DTC

^ A scan tool can clear the DTC from the PCM history. The PCM clears the DTC from the PCM history if the vehicle completes 40 warm-up cycles without a failure reported.

^ The PCM cancels the DTC default actions when the fault no longer exists and the ignition is OFF long enough in order to power down the PCM.

DIAGNOSTIC AIDS

^ Charging the battery with a battery charger and jumpstarting an engine may set DTCs.

^ If this DTC is set when an accessory is operated, inspect for faulty connections or an excessive current draw.

^ Inspect for faulty electrical connections at the starter solenoid.

^ Inspect for faulty electrical connections at the fusible link.

^ Inspect for loose or damaged terminals at the generator.

^ Inspect the generator belt wear condition and tension.

^ First diagnose and clear any engine DTCs that are present. Then inspect for any transmission DTCs that may have reset.

TEST DESCRIPTION

4. This step tests the charging system voltage.

5. This step tests the battery voltage input at the PCM.

7. This step tests the ignition voltage inputs at the PCM.
