## DTC Troubleshooting: P1213 (11-1)

DTC P1213 (11-1): | IMA Circuit Low Voltage

1. | Reset the ECM/PCM.

2. | Start the engine, then let it idle for more than 5 seconds.

3. | Check for Temporary DTCs or DTCs with the HDS or a scan tool. Is DTC P1213 indicated? YES - Go to 4. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the IMA and the ECM/ PCM.n

4. | Turn the ignition switch OFF.

5. | Disconnect the IMA 3P connector.

6. | Turn the ignition switch ON (II).

7. | Measure voltage between IMA 3P connector terminals No. 1 and No. 3. Is there about 5 V? YES - Go to 8. NO - Go to 14.

8. | Turn the ignition switch OFF.

9. | Disconnect ECM/PCM connector A (31P).

10. | At the wire harness side, check for continuity between IMA 3P connector terminal No. 2 and body ground. Is there continuity? YES - Repair short in the wire between the ECM/PCM (A31) and the IMA.n NO - Go to 11.

11. | Reconnect the IMA 3P connector and ECM/PCM connector A (31P).

12. | Turn the ignition switch ON (II).

13. | Measure voltage between ECM/PCM connector terminals A10 and A31. Is there about 0.5-4.5 V? YES - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/ PCM.n NO - Replace the IMA.n

14. | Measure voltage between ECM/PCM connector terminals A10 and A20. Is there about 5 V? YES - Repair open in the wire between the ECM/PCM (A20) and the IMA.n NO - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/ PCM.n
