Transmission Code

SYMPTOM
P0562 - LOW BATTERY VOLTAGE

WHEN MONITORED
With the engine running and the PCM has closed the Transmission Control Relay.

SET CONDITION
If the battery voltage of the Transmission Control Relay Output Sense circuit(s) to the PCM is less than 10.0 volts for the period of 15 seconds.

NOTE: P0562 generally indicates a gradually falling battery voltage or a resistive connection(s) to the PCM. The DTC will also set if the battery voltage sensed at the PCM is less than 6.5v for 200ms or where Transmission Control Relay Output circuits is less than 7.2v for 200ms.

POSSIBLE CAUSES
- Related charging system DTC's
- Intermittent wiring and connectors
- Ground circuit open or high resistance
- Fused B+ circuit to PCM high resistance
- Transmission control relay output to TCM open or high resistance
- Transmission control relay open or high resistance
- PCM - Low battery voltage
