DTC Troubleshooting: P1214 (11-2)

DTC P1214 (11-2):  IMA Circuit High Voltage

1.Reset the ECM/PCM.

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

Is DTC P1214 indicated?


YES - Go to 3.


NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the IMA and at the  ECM/ PCM.n


3.Turn the ignition switch OFF.

4.Disconnect the IMA 3P connector.

5.Turn the ignition switch ON (II).

6.Measure voltage between IMA 3P connector terminals No. 1 and No. 3.

 

Is there about 5 V?


YES - Go to 8.


NO - Go to 7.

7.Measure voltage between ECM/PCM connector terminals E4 and E5.

 

Is there about 5 V?


YES - Repair open in the wire between the  ECM/ PCM (E4) and the IMA.n


NO - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original  ECM/ PCM.n


8.Connect ECM/PCM connector terminal E15 and body ground with a jumper wire.

 

9.At the wire harness side, check for continuity between IMA 3P connector terminals No. 2 and body ground.

 

Is there continuity?


YES - Replace the IMA.n


NO - Repair open in the wire between the  ECM/ PCM (E15) and the IMA.n
