Circuit/System Verification

1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and

15.0 V.

瀚慖f not within the specified range, refer to Charging System Test (See: Starting and Charging/Testing and Inspection/Component Tests

and General Diagnostics/Charging System Test).

2. If all circuits test normal, replace the FPCM.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Control Module References (See: Testing and Inspection/Programming and Relearning) for FPCM replacement, setup, and programming.

DTC Descriptor

DTC P0562

- System Voltage Low

DTC P0563

- System Voltage High

Circuit/System Description

The transmission control module continuously monitors the system voltage on the Ignition voltage circuits. The transmission control module is

located within the control solenoid valve assembly and is not serviced separately. Lower than normal voltage may be inadequate to operate the

transmission control solenoids properly. Improper solenoid operation may cause erratic transmission operation, which may result in internal

transmission damage.
