DTC B1324: Lost Communication with Meter [12/2019 - 10/2022]: Procedure

  1. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY POWER SOURCE) 
    1. Disconnect the H21 combination meter assembly connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      H21-21 (ES) - Body ground Always Below 1 Ω
    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage

      Tester Connection Condition Specified Condition
      H21-40 (B) - Body ground*1 Ignition switch off 11 to 14 V
      H21-40 (B) - Body ground*2 Always 11 to 14 V
      H21-39 (IG+) - Body ground Ignition switch ON 11 to 14 V*3
      10.5 to 16 V*4
      1. *1: for HV Model
      2. *2: for Gasoline Model
      3. *3: w/o Stop and Start System
      4. *4: w/ Stop and Start System
