Circuit/System Verification

1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6-15.0

volts.

瀚慖f the voltage is not within the specified range, or the charge indicator light is ON, refer to Charging System Test (See: Starting and

Charging/Testing and Inspection/Component Tests and General Diagnostics/Charging System Test).

2. Observe the scan tool TCM Ignition Voltage parameter. The reading should be between 12.6-15.0 volts.

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Ignition OFF, disconnect the 20-way harness connector at the transmission.
