    INSPECT ABS MOTOR RELAY


    1. B004X91C13
      *1 ABS Motor Relay (ABS MTR NO. 1 or ABS MTR NO. 2 relay)
      *a MR1 or MR2 Terminal
      *b R1- or R2- Terminal
      *c BM1 or BM2 Terminal
      *d +BM1 or +BM2 Terminal

      Remove the ABS motor relay (ABS MTR NO. 1 and ABS MTR NO. 2 relays).

    2. Check both the relay case and the terminal for deformation and corrosion.

      OK
      No deformation or corrosion.

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

      Standard Resistance
      Table 1. for ABS MTR NO. 1 relay
      Tester Connection Condition Specified Condition
      3 (BM1) - 5 (+BM1) Voltage is not applied between terminals 1 (MR1) and 2 (R1-) 10 kΩ or higher
      3 (BM1) - 5 (+BM1) Voltage is applied between terminals 1 (MR1) and 2 (R1-) Below 1 Ω
      Table 2. for ABS MTR NO. 2 relay
      Tester Connection Condition Specified Condition
      3 (BM2) - 5 (+BM2) Voltage is not applied between terminals 1 (MR2) and 2 (R2-) 10 kΩ or higher
      3 (BM2) - 5 (+BM2) Voltage is applied between terminals 1 (MR2) and 2 (R2-) Below 1 Ω

      If the result is not as specified, replace the ABS motor relay (ABS MTR NO. 1 and/or ABS MTR NO. 2 relay).
