DTC P0562

DTC P0562 System voltage low (KAM)
DETECTION CONDITION 
  • The PCM monitors the battery voltage when the engine is running. If the voltage is less than 2.5 V, the PCM determines that the system voltage is low.

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
  • FREEZE FRAME DATA (Mode 2/Mode 12) is available.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • Fuse malfunction
  • Short to ground in wiring harness between battery positive terminal and PCM terminal 1 BA
  • Looseness of battery positive terminal
  • Battery malfunction
  • PCM connector or terminals malfunction
  • Open circuit in wiring harness between battery positive terminal and PCM terminal 1 BA
  • PCM malfunction
G07878126
DIAGNOSTIC PROCEDURE

STEP INSPECTION ACTION
1 VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED 
  • Has the FREEZE FRAME DATA (Mode 12) been recorded?
Yes Go to the next step.
No Record the FREEZE FRAME DATA (Mode 12) on the repair order, then go to the next step.
2 VERIFY RELATED REPAIR INFORMATION AVAILABILITY 
  • Verify related Service Bulletins and/or on-line repair information availability.
  • Is any related repair information available?
Yes Perform repair or diagnosis according to the available repair information.
  • If the vehicle is not repaired, go to the next step.
No Go to the next step.
3 INSPECT FUSE 
  • Inspect the fuse.
  • Is there any malfunction?
Yes If the fuse is melting:
  • Go to the next step.

    If the fuse is deterioration:

  • Replace the suspected fuse, then go to Step 9.
No Go to Step 5.
4 INSPECT BATTERY CIRCUIT FOR SHORT TO GROUND 
  • Turn the ignition switch off.
  • Disconnect the battery positive and negative posts.
  • Inspect for continuity between battery positive terminal (wiring harness-side) and body ground.
  • Is there continuity?
Yes Repair or replace the wiring harness for a possible short to ground or replace the suspected fuse, then go to Step 9.
No Inspect for continuity between battery positive terminal and other wiring harness.
Repair or replace the suspected wiring harness or replace the suspected fuse, then go to Step 9.
5 INSPECT BATTERY POSITIVE TERMINAL FOR POOR INSTALLATION 
  • Turn the ignition switch off.
  • Inspect for looseness of the battery positive terminal.
  • Is there any malfunction?
Yes Connect the battery positive terminal correctly, then go to Step 9.
No Go to the next step.
6 INSPECT BATTERY 
Yes Recharge or replace the battery, then go to Step 9.
(See BATTERY RECHARGING [13B-MSP] ).
(See BATTERY REMOVAL/INSTALLATION [13B-MSP] ).
No Go to the next step.
7 INSPECT PCM CONNECTOR FOR POOR CONNECTION 
  • Turn the ignition switch off.
  • Disconnect the PCM connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Is there any malfunction?
Yes Repair or replace the connector and/or terminals, then go to Step 9.
No Go to the next step.
8 INSPECT BATTERY CIRCUIT FOR OPEN CIRCUIT 
  • Battery positive terminal and PCM connector are disconnected.
  • Turn the ignition switch off.
  • Inspect for continuity between battery positive terminal (wiring harness-side) and PCM terminal 1BA (wiring harness-side).
  • Is there continuity?
Yes Go to the next step.
No Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9 VERIFY TROUBLESHOOTING OF DTC P0562 COMPLETED 
  • Make sure to reconnect all disconnected connectors.
  • Clear the DTC from the PCM memory using the M-MDS.

    (See AFTER REPAIR PROCEDURE ).

  • Perform the KOEO or KOER self test.

    (See KOEO/KOER SELF TEST ).

  • Is the same DTC present?
Yes Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION ).
No Go to the next step.
10 VERIFY AFTER REPAIR PROCEDURE 
Yes Go to the applicable DTC inspection.
(See DTC TABLE ).
No DTC troubleshooting completed.
