A. Inspect the PCM Module DTC's

1. Open the hood. Install a battery charger and verify that the charging rate provides 13.2 to 13.5 volts. Do not allow the charger to time out during the flash process. Set the battery charger timer (if so equipped) to continuous charge.

NOTE:
Use an accurate stand-alone voltmeter. The battery charger voltmeter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.

2. Connect the wiTECH VCI pod to the vehicle data link connector.

3. Place the ignition in the "RUN" position.

4. Open the wiTECH diagnostic application.

5. Starting at the "Select Tool" screen, select the row/tool for the wiPOD device you are using.

6. Enter your "User id" and "Password", then select "OK".

7. Select the "Next" tab at the bottom of the screen.

8. From the "Vehicle View" screen, click on the "All DTC's" tab.

9. Check for Diagnostic Trouble Codes (DTC's):

> If there are no DTC's, reprogram the PCM module. Continue with Section B. Reprogram the PCM Module.

> If it has been determined that 2 or more of the Circuit High DTC's are active or stored, or 2 or more of the Circuit Low DTC's are active or stored, replace the PCM module. Continue with one of the following sections:

> Section C. (RT) Grand Caravan/Town and Country PCM Replacement

> Section D. (DS) Ram 1500 Series Pick Up Truck PCM Replacement

> If there are DTC's other than the Circuit High DTC's or the Circuit Low DTC's, reprogram the PCM module. Continue with Section B. Reprogram the PCM Module.

NOTE:
DTC P0032 = O2 Sensor 1/1 Heater Circuit High.
DTC P0038 = O2 Sensor 1/2 Heater Circuit High.
DTC P0052 = O2 Sensor 2/1 Heater Circuit High.
DTC P0058 = O2 Sensor 2/2 Heater Circuit High.
DTC P0031 = O2 Sensor 1/1 Heater Circuit Low.
DTC P0037 = O2 Sensor 1/2 Heater Circuit Low.
DTC P0051 = O2 Sensor 2/1 Heater Circuit Low.
DTC P0057 = O2 Sensor 2/2 Heater Circuit Low.
