HYBRID CONTROL SYSTEM Pattern Select Switch Sport Mode Circuit

DESCRIPTION

When selecting SPORT mode, the switch operation signal is sent to the ECM. Following this, the drive torque is optimally controlled to obtain a sporty feel in response to the driver's accelerator pedal operation.

4. INSPECT MODE SWITCH (COMBINATION SWITCH ASSEMBLY)

   
   

   1. Remove the mode switch (combination switch assembly).

      Click here

   2. 

      *a	Component without harness connected (Mode Switch (Combination Switch Assembly))

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

      Standard Resistance
      Tester Connection Condition Specified Condition 10 (PWR) - 16 (E) Mode switch (combination switch assembly) being turned and held at SPORT position Below 50 Ω Mode switch (combination switch assembly) not turned 10 kΩ or higher 9 (NORM) - 16 (E) Mode switch (combination switch assembly) being pushed and held Below 50 Ω Mode switch (combination switch assembly) not pushed 10 kΩ or higher

   3. Install the mode switch (combination switch assembly).

      Result
      Proceed to OK NG

   OK

5. CHECK HARNESS AND CONNECTOR (MODE SWITCH (COMBINATION SWITCH ASSEMBLY) - BODY GROUND)

   
   

   1. Disconnect the O78 mode switch (combination switch assembly) connector.

   2. 

      *a	Front view of wire harness connector (to Mode Switch (Combination Switch Assembly))

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

      Standard Resistance
      Tester Connection Condition Specified Condition O78-16 (E) - Body ground Always Below 1 Ω

   3. Reconnect the O78 mode switch (combination switch assembly) connector.

      Result
      Proceed to OK NG

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

6. CHECK HARNESS AND CONNECTOR (ECM - MODE SWITCH (COMBINATION SWITCH ASSEMBLY))

   
   

   1. Disconnect the A72 and F6 ECM connectors

   2. Disconnect the O78 mode switch (combination switch assembly) connector.

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

      

      *a

      Front view of wire harness connector (to ECM)

      *b

      Front view of wire harness connector (to Mode Switch (Combination Switch Assembly))

      Standard Resistance (w/o Adaptive Variable Suspension)
