NOTE
Make sure ignition switch is always OFF when measuring resistance.
1) Turn ignition switch OFF.
2) Disconnect battery cables from battery.
3) Disconnect wire harness connector from ECM.
4) Connect the tester probes to terminal (wire harness side) and measure resistance according to the “Resistance
Table” (Page 1C-7).
