Pinpoint Test J: P0702, P0882, P0883

Normal Operation and Fault Conditions 

The transmission control system is an integrated part of the PCM. If the PCM supply voltage drops below or rises above operating voltage, the transmission control system may not operate properly.

DTC Fault Trigger Conditions 

Possible Causes 

• Low voltage to the PCM
• Low battery condition
• Charging system concern
• Connectors damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals

• Using a diagnostic scan tool, carry out the KOEO and KOERPCM self-tests.

Are any system voltage diagnostic trouble codes (DTCs) present? 

• Carry out the Battery Condition Test. REFER to: Battery - 3.5L Duratec (202kW/275PS)/3.5L EcoBoost (235kW/320PS) .

Did the battery pass the condition test? 

• Using a diagnostic scan tool, clear all PCM diagnostic trouble codes (DTCs).

• Turn off all interior lights, exterior lights and accessories.

• NOTE: Do not allow the engine speed to increase above 2, 000 RPM while performing this step or the generator may self-excite and result in default charging system output voltage. If engine speed goes above 2, 000 RPM, turn the engine off and restart the engine before performing this step.

  Start and run the engine at approximately 1, 500 RPM for 3 minutes while monitoring the battery voltage.

Does the battery voltage stay between 13 and 15.2 volts? 

• Ignition OFF.

• Disconnect all PCM connectors.

• Using a good light source, inspect all  disconnected electrical connectors for the following:
  • corrosion (install new connector or terminals - clean module pins)
  • damaged or bent pins - install new terminals/pins
  • pushed-out pins - install new pins as necessary
  • spread terminals - install new terminals as necessary

• Check the PCM power and ground circuits for opens or short to ground. Refer OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the cause of any circuit faults.

• Reconnect all PCM connectors. Make sure they seat and latch properly

• Ignition ON.

• Using a diagnostic scan tool, clear all diagnostic trouble codes (DTCs) from the PCM.

• Ignition OFF.

• Ignition ON.

• Using a diagnostic scan tool, carry out the KOEO and KOERPCM self-tests.

Is DTC P0702, P0882, and/or P0883 still present? 

Yes
