  2. Using an external ohmmeter, check resistance of No. 1 driver circuit (Gray/Red wire) between IAC motor connector and PCM connector terminal No. 39 on XJ and YJ bodies or terminal No. 59 on ZJ body. If resistance is less than 5 ohms, replace PCM. If resistance is more than 5 ohms, repair open in No. 1 driver circuit.
