LVPS (PL15.1.10) check
1. Disconnect the LVPS connectors J163, J165 and J164.
2. Turn on the Harness Assy AC SW (PL15.1.11).
3. Measure the voltages between the following terminals.
P163-1 <=> P163-2 (24V DC)
P165-1 <=> P165-2 (5V DC)
P165-3 <=> P165-4 (3.3V DC)
Are the voltages normal between each terminal?
Go to step 3.
Replace the LVPS. (Refer to
Ch4-4.2.18.3)
3
Harness Assy LVRPG (PL15.2.4) check
1. Turn off the Harness Assy AC SW (PL15.1.11), and then connect J164 to the LVPS
(PL15.1.10).
2. After connecting the connector, turn on the Harness Assy AC SW (PL15.1.11).
Is the v3.3V DC between P/J164-1 <=> P/J164-2?
Go to step 4.
Check for a Harness Assy
LVRPG (PL15.2.4) frame short.
4
Harness Assy LVNC (PL15.2.1) check
1. Turn off the Harness Assy AC SW (PL15.1.11), and then connect J165 to the LVPS
(PL15.1.10).
2. After connecting the connector, turn on the Harness Assy AC SW.
Is the v5V DC between P/J165-1 <=> P/J165-2?
Go to step 5.
Check for a Harness Assy
LVNC (PL15.2.1) frame short.
5
Harness Assy 24V (PL15.2.6) check
1. Turn off the Harness Assy AC SW (PL15.1.11), and then connect J163 to the LVPS
(PL15.1.10).
2. After connecting the connector, turn on the Harness Assy AC SW.
Is the v24V DC between P/J163-1 <=> P/J163-2?
End of procedure
Check for a Harness Assy 24V
(PL15.2.6) frame short.
