DTC 11: IMA Circuit Malfunction Reset the ECM/PCM (see page 11-468). Start the engine, then let it idle for more than 5 seconds. Is the MIL on and does it indicate DTC 11? YES - Go to step 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the IMA sensor and at the ECM/PCM. Turn the ignition switch OFF. Turn the ignition switch ON (II). Measure voltage between ECM/PCM connector terminals E4 and E5. ECM/PCM CONNECTOR E (31P) Wire side of female terminals Is there about 5 V? YES - Go to step 6. NO - Substitute a known-good ECM/PCM and recheck. If symptom/indication goes away, replace the original ECM/PCM. Measure voltage between ECM/PCM connector terminals E4 and E15. ECM/PCM CONNECTOR E (31P) Wire side of female terminals

Is there about 0.5-4.5 V? YES - Substitute a known-good ECM/PCM and recheck. If symptom/indication goes away, replace the original ECM/PCM. NO - Go to step 7. Measure voltage between ECM/PCM connector terminals E4 and E15. ECM/PCM CONNECTOR S (31P) Wire side of female terminals Is there about 5 V? YES - Go to step 8. NO - Go to step 13. Turn the ignition switch OFF. Disconnect the IMA 3P connector. Turn the ignition switch ON (II). Measure voltage between IMA 3P connector terminals No. 1 and No. 3. IMA 3P CONNECTOR Wire side of female terminals Is there about 5 V? YES - Go to step 12. NO - Repair open in the wire between the ECM/PCM (E4) and the IMA.
