DESCRIPTION

When a signal is input from the P position switch (transmission shift main switch) or shift lever, the hybrid vehicle control ECU assembly transmits a P control (PCON) signal to the transmission control ECU assembly. Based on this signal, the transmission control ECU assembly actuates the shift control actuator assembly in order to mechanically lock or unlock the counter drive gear in the hybrid vehicle transaxle assembly.

The P position state (engaged or released) of the actuator assembly is sent to the hybrid vehicle control ECU assembly and certification ECU as a P position (PPOS) signal.

      A132-23 (PPOS) - Body ground Power switch on (IG) Below 1 V

      Note

      Turning the power switch on (IG) with the hybrid vehicle control ECU assembly connectors disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    6. Turn the power switch off.

    7. Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      E135-8 (PCON) - A132-22 (PCON) Power switch off Below 1 Ω
      E135-15 (PPOS) - A132-23 (PPOS) Power switch off Below 1 Ω
      A132-23 (PPOS) - E35-25(PPOS) Power switch off Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      E135-8 (PCON) or A132-22 (PCON) - Body ground and other terminals Power switch off 10 kΩ or higher
      E135-15 (PPOS), A132-23 (PPOS) or E35-25(PPOS) - Body ground and other terminals Power switch off 10 kΩ or higher

    8. Reconnect the E35 certification ECU connector.

    9. Reconnect the A132 transmission control ECU assembly connector.

    10. Reconnect the E135 hybrid vehicle control ECU assembly connector.
