DTC Code DTC Name
P06A4-209 Sensor Reference Voltage "D" Circuit Low
P06A5-210 Sensor Reference Voltage "D" Circuit High

DESCRIPTION

The power management control ECU monitors voltage of 5 V power supply (VC) used for the sensors. If the power management control ECU detects a malfunction, it will set a DTC.

DTC No. INF Code DTC Detection Condition Trouble Area
P06A4 209

VC power-supply voltage is lower than 4.2 V

(1 trip detection logic)

 Power management control ECU
P06A5 210

VC power-supply voltage is higher than 5.8 V

(1 trip detection logic)

INSPECTION PROCEDURE

Tech Tips

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


  1. Turn the power switch on (IG) and wait for 15 seconds or more.

PROCEDURE


  1. CHECK DTC OUTPUT (HYBRID CONTROL)


    1. Connect the Techstream to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Check if DTCs are output.

      Tech Tips

      P06A4-209 or P06A5-210 may be set due to a malfunction which also causes DTCs in the preceding table to be set. In this case, first troubleshoot the output DTCs in the preceding table. Then, perform a test to attempt to reproduce the problems, and check that no DTCs are output.

    5. Turn the power switch off.
