20. Reset the ECM/PCM with the HDS.
21. Do the ECM/PCM idle learn procedure (see page
11-310).
22. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at CMP sensor A 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.
23. Reconnect all connectors.
24. 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).
25. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at CMP sensor A and the ECM/PCM. If the
ECM/PCM was updated, substitute a known-good
ECM/PCM (see page 11-7), then recheck. If the
ECM/PCM was substituted, go to step 1.
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.
