Pinpoint Test G : DTC P0702, P0882, P0883, P1397

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

Transmission Controls - 6R100 for schematic and connector information.

Normal Operation and Fault Conditions

The PCM monitors system voltage and sets a DTC if the voltage available to control the transmission rises above or falls below threshold.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
PCM P0702:00	Transmission Control System Electrical: No Sub Type Information	This DTC illuminates the wrench light in conjunction with P0882 and/or P0883. Resolve the more specific DTC first.
PCM P0882:00	TCM Power Input Signal Low: No Sub Type Information	This DTC indicates the PCM detected a supply voltage of less than 9 volts. At low voltage, the solenoid drivers may not be able to function properly, so the failsafe logic opens the high side switch which disables all gears except park, reverse, neutral, and 5M.
PCM P0883:00	TCM Power Input Signal High: No Sub Type Information	This DTC indicates the PCM detected a supply voltage of greater than 21 volts. The failsafe logic opens the high side switch which disables all gears except park, reverse, neutral, and 5M.
PCM P1397:00	System Voltage Out Of Self Test Range: No Sub Type Information	This DTC indicates the PCM detected a voltage supply outside the allowed self-test range of 11 to 18 volts during a KOEO or a KOER self-test.

Possible Sources

Charging system concern
Jump starting the vehicle with a battery pack
High resistance ground condition
Low voltage to the PCM

G1 RECHECK FOR THE VOLTAGE FAULT DTC (DIAGNOSTIC TROUBLE CODE) IN THE PCM (POWERTRAIN CONTROL MODULE)

Ignition OFF.

Disconnect and inspect all PCM connectors.

Repair:
- 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

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

Reconnect all PCM connectors.

Ignition ON.

Using a diagnostic scan tool, clear the DTC from the PCM.

Wait 10 seconds.

Using a diagnostic scan tool, carry out the KOEO and KOER PCM self-tests.

Is DTC P0702, P0882, P0883 and/or P1397 still present?

Yes	DIAGNOSE the vehicle charging concern. REFER to: Charging System - 6.2L V8/6.8L Triton-30V - V10 .

No	If the PCM does not communicate with the scan tool, REFER to: COMMUNICATIONS NETWORK Otherwise, the system is operating properly at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.
