Test 21, Check Crankshaft Sensor Ignition Ground

With key off, disconnect ECA. Disconnect diagnostic cable connector from crankshaft sensor. Connect an ohmmeter between breakout box pins No. J55 (IGND S) and J60 (BAT -).

If resistance is less than 5 ohms, go to next test. If resistance is not less than 5 ohms, check connectors, repair or replace harness and check for fault codes. If vehicle still does not start, go to next test.
