  • SDM
  • SDM wiring harness
  1. Ignition OFF, remove the under hood SIR Display Fuse 25.
  2. Ignition ON, with a DMM, test for 9-16 V between the voltage supply side and ground.
    • If not the specified range, refer to DTC B1370  in wiring systems and power management.
  3. Ignition OFF, remove the SDM harness connector.
  4. Ignition OFF, test for less then 1 Ω of resistance between the ignition 1 voltage circuit terminal 32 and the under hood fuse block terminal 28.
    • If greater then the specified range, test the circuit for an open/high resistance.
  5. Ignition ON, with a DMM, test for less then 1 volt between the ignition 1 voltage circuit terminal 32 and the under hood fuse block terminal 28.
