Ω (Resistance)
NOTE:
Make sure that the ignition switch is always OFF when measur-
ing resistance.
1. Disconnect the battery cables from the battery.
2. Disconnect the wire harness from the ECM.
3. Connect the tester probes to the terminal of the wire harness
side, and measure resistance according to the “RESISTANCE
TABLE”.
