DTC Troubleshooting (cont’d)
36. Monitor the OBD STATUS for DTC P050B in the
DTCs MENU with the HDS.
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 were indicated in step 35, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the CKP sensor,
the throttle body, the MAF/IAT sensor, ECT
sensor 1, ECT sensor 2, and the ECM/PCM. If the
ECM/PCM was updated, substitute a known-good
ECM/PCM (see page 11-7), then go to step 33. If the
ECM/PCM was substituted, go to step 1. If the
screen indicates EXECUTING, keep idling until a
result comes on. If the screen indicates OUT OF
CONDITION, go to step 33. NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 If any high current load accessories are installed, this DTC can be set.
 If DTC P16BB and/or P16BC is stored at the same time as DTC P0562, troubleshoot DTC P16BB and/or P16BC
first, then recheck for DTC P0562.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. Check under these conditions: A/Con
 Temperature control at maximum cool
 Blower fan at maximum speed
 Rear window defogger on
 Headlights on high beam
5. Hold the engine speed at 2,000 rpm (A/T in P or N, M/T in neutral) for 1 minute.
6. Check for Temporary DTCs or DTCs with the HDS.
Replace the alternator (see page 4-34), then
go to step 7.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the alternator and the under-hood fuse/relay box,
and check the battery performance (see page
22-67).Charging System Low Voltage
