When the TCM detects low voltage, DTC P0562 sets. DTC P0562 is a type C DTC.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
Conditions for Running the DTC
The engine speed is greater than 1,200 r.p.m.
Conditions for Setting the DTC
The TCM detects system voltage less than 11 V for 10 seconds.
Action Taken When the DTC Sets
• The TCM does not request the engine control module (ECM) to illuminate the MIL.
• The TCM records the operating conditions when the conditions for setting the DTC are met. The TCM records this
information as a Failure Record.
• The TCM stores DTC P0562 in TCM history.
Conditions for Clearing the DTC
• The TCM clears the DTC from TCM history if the vehicle completes 40 warm-up cycles without a non-emission
related diagnostic fault occurring.
• Tech 2 can clear the DTC.
Diagnostic Aids
• Observe the instrument cluster’s multi-function display messaging that would indicate the electrical system requires
service.
• Inspect for the following conditions:
• Loose or damaged terminals at the generator, and
• Loose or worn generator drive belt.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
3 The alternator warning indicator will illuminate if there is a problem with the charging system of the vehicle.
4 Checks the charging system voltage with a nominal load.
5 Checks if the ignition voltage measurement reported by the TCM is within acceptable parameters.
7 Checks if there is battery voltage supplied to the TCM.
8 Checks if there is battery voltage supplied through the ignition circuit to the TCM.
9 Checks the ground circuits of the TCM.

2 1 Connect Tech 2 to the DLC.
2 Turn on the ignition, with the engine off.
NOTE
Before clearing the DTC, use the Tech 2 Freeze
Frame/Failure Record to record the transmission
parameters at the time the DTC set. Using Tech 2 to clear
the DTC(s) erases the Freeze Frame/Failure Record
records from the TCM.
3 On Tech 2 select: Transmission / Automatic Transmission / Diagnostic
Trouble Codes / Freeze Frame.
4 Select the relevant DTC and note the parameters at the time of the DTC setting.
5 On Tech 2 select:
Diagnostic Trouble Codes / Clear Engine & Transmission
DTCs.
6 Follow the instructions on Tech 2 and clear the DTCs.
7 Using a multimeter set to measure voltage, probe across the battery terminals.
Does the multimeter display greater than 11 V? Go to Step 3 Check the
serviceability of the battery, refer to
8A Electrical-Body and Chassis
3 1 Start the engine.
2 Allow the engine to warm up to normal operating temperature.
Is the alternator fail warning indicator illuminated? Refer to
6D1-1 Charging system – V6 Go to Step 4
4 1 Turn on the high beam headlamps.
2 Turn the HVAC fan control to the highest speed setting.
3 Turn on the rear window demister.
4 Increase the engine speed to 1,500 r.p.m.
5 Using a multimeter set to measure voltage, probe across the battery terminals.
Does the multimeter display 12.5 – 14.5 V? Go to Step 5 Refer to
6D1-1 Charging system – V6
5 1 Increase the engine speed to 1,500 r.p.m.
2 On Tech 2 select: Data Display / Transmission Data
Does Tech 2 display the Ignition Voltage parameter within 12.5 –
14.5 V? Check for an
intermittent fault in the circuit, refer to
8A Electrical-Body
and Chassis Go to Step 6
6
Check the fuses EB-4 and C-8 for serviceability.
Are the fuses serviceable?
Go to Step 7 Replace the
affected fuse(s). If the fuse(s) blow
again, check for a short to ground in the fuses circuit
Go to Step 13
7 1 Turn off the ignition.
2 Disconnect the TCM connector C-96.
3 Using a multimeter set to measure voltage, probe between connector C-96 pin 32 and a known ground.
Does the multimeter display battery voltage? Go to Step 8 Check measured
circuits for an open,
high resistance or short to ground
Repair or replace
the affected circuit

Conditions for Setting the DTC
The TCM detects system voltage greater than 18 V for 10 seconds.
Action Taken When the DTC Sets
•
The TCM does not request the engine control module (ECM) to illuminate the MIL.
• The TCM records the operating conditions when the conditions for setting the DTC are met. The TCM records this
information as a Failure Record.
• The TCM stores DTC P0563 in TCM history.
Conditions for Clearing the DTC
•
The TCM clears the DTC from TCM history if the vehicle completes 40 warm-up cycles without a non-emission
related diagnostic fault occurring.
• Tech 2 can clear the DTC.
Diagnostic Aids
• Observe the instrument cluster’s multi-function display for messaging that would indicate the electrical system
requires service.
• Use Tech 2 to inspect all other modules for voltage related DTCs.
• Running the engine with a battery charger attached may cause DTC P0563 to set.
• Inspect the charging circuit for high resistance.
• Inspect the vehicle battery for open or sulphated cells.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
3 The alternator warning indicator will illuminate if there is a problem with the charging system of the vehicle.
4 Checks the charging system voltage with a minimal load.
5 Checks if there is a difference between the Tech 2 reading and the voltage measure in an earlier step.
