      *a

      Component without harness connected:

      (Brake Actuator Assembly)

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

      Tech Tips

      Perform the check with the actuator at the lowest temperature possible.

      Standard resistance
      Tester Connection Condition Specified Condition
      37 (SMC1) - 36 (BS1) Always 15.3 to 25.0 Ω
      19 (SMC2) - 20 (BS2)
      44 (FRA+) - 43 (FRA-) 3.6 to 6.0 Ω
      28 (FRR+) - 27 (FRR-)
      35 (FLA+) - 38 (FLA-)
      21 (FLR+) - 22 (FLR-)
      39 (RRA+) - 40 (RRA-)
      41 (RLA+) - 42 (RLA-)
      23 (RRR+) - 24 (RRR-) 4.4 to 7.0 Ω
      25 (RLR+) - 26 (RLR-)

      If the result is not as specified, replace the brake actuator.

  2. CHECK BRAKE ACCUMULATOR PUMP

      *a

      Component without harness connected:

      (Brake Accumulator Pump)

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

      Standard resistance
      Tester Connection Condition Specified Condition
      A2 (BM1) - A4 (GND1) Always 10 Ω or less
      B2 (BM2) - A4 (GND1)
      A2 (BM1) - B2 (BM2) Below 1 Ω
      A4 (GND1) - B1 (GND2)
      A2 (BM1) - A1 (MTT) 950 to 1050 Ω
      B2 (BM2) - A1 (MTT)

      If the result is not as specified, replace the brake accumulator pump.
