terminals at the alternator and the ECM/PCM, then
go to step 1.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.
27. Reconnect all connectors.
28. Update the ECM/PCM if it does not have the latest software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
29. Start the engine.
30. Check under these conditions: A/Con
Temperature control at maximum cool

If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting. NOTE:
Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
If DTC P0111 is stored at the same time as DTC P2183, troubleshoot DTC P0111 first, then recheck for DTC
P2183.

Go to step 2.
Repair the connections or the terminals, then
go to step 27.
2. Turn the ignition switch to ON (II).
3. Check for Temporary DTCs or DTCs with the HDS.
Go to step 15.
Go to step 4.
4. Start the engine, and let it idle for 10 minutes.
5. Check ECT SENSOR 2 in the DATA LIST with the HDS.
ReplaceECTsensor2(seepage11-225),then
go to step 27.
Go to step 6.
6. Turn the ignition switch to LOCK (0).
7. Drain the coolant (see page 10-8).
8. Remove ECT sensor 2 (see page 11-225).
9. Allow ECT sensor 2 to cool to ambient temperature.
