NS14, Code 11 - Checking Distributor Pick-Up Harness
- Turn ignition off. Connect DRB II to engine harness connector. Disconnect Black distributor reference pick-up coil connector. Turn ignition switch to "RUN" position. Connect a jumper wire between distributor reference pick-up coil connector cavities No. 2 and No. 3. Make and break this connection several times. Put system in Diagnostic Test Mode. Record all codes.
- If 88-11-12-54-55 is displayed, disregard code 54 and go to step 4). If 88-12-54-55 is displayed, disregard code 54. With distributor pick-up coil connector disconnected, connect voltmeter to distributor pick-up coil connector cavity No. 1 and ground.
- If voltmeter reading is at least 7 volts, replace distributor reference pick-up. Before replacing pick-up, ensure distributor harness connector terminals are not spread apart causing a poor connection. Also ensure distributor rotor turns while cranking engine. If voltmeter reading is zero volts, repair Orange wire to connector cavity No. 1 for an open circuit to wiring harness splice.
- With ignition on, connect positive voltmeter lead to distributor connector cavity No. 3. Connect negative voltmeter lead to distributor connector cavity No. 2. If voltmeter reading is at least 4 volts, replace SMEC.
- If voltmeter reading is zero volts, connect positive voltmeter lead to distributor connector cavity No. 3. Connect negative voltmeter lead to a good engine ground. If voltmeter reading is at least 4 volts, repair Black/Light Blue wire in distributor connector cavity No. 2 for an open circuit to wiring harness splice.
- If voltmeter reading is zero volts, turn ignition off. Disconnect 60-pin connector from SMEC. Connect an ohmmeter to distributor connector cavity No. 3 and 60-pin connector cavity No. 47. If there is no continuity, repair Gray wire to 60-pin connector cavity No. 47 or an open circuit to distributor connector.
- If there is continuity, replace SMEC for a defective logic board. Before replacing SMEC, ensure terminal in connector cavity No. 47 is not damaged causing a poor connection.
