Harness Assy TMPA (PL4.2.3), Harness Assy TMPB (PL15.2.12) continuity
Check the continuity for the following lines.
J24-1 <=> P2361-4/J2361-1 <=> J231-4
J24-2 <=> P2361-3/J2361-2 <=> J231-3
J24-3 <=> P2361-2/J2361-3 <=> J231-2
J24-4 <=> P2361-1/J2361-4 <=> J231-1
Is there continuity in all lines?
Go to step 7.
Replace the harness with no
continuity.
7
PWBA MCU & HVPS (PL15.1.2) continuity
1. Disconnect the P/J11 and P/J24 connector from the PWBA MCU & HVPS. (Refer to Ch4-
2. Check the continuity between P11-17 <=> P24-4.
Is the continuity normal between P11-17 <=> P24-4 normal?
Replace the PWBA MCU &
HVPS. (Refer to Ch4-4.2.18.1)
Go to step 8.
8
Harness Assy DRV 1 (PL15.2.2) continuity
1. Disconnect the P/J41 connector from the PWB Drive (PL15.1.15).
2. Measure the voltage between connectors P41-24 <=> P42-14/15 of the PWB Drive.
Is there 5V DC between P41-24 <=> P42-14/15.
Replace the Harness Assy DRV 1
(PL15.2.2).
Go to step 9.
9
PWB Drive (PL15.1.15) continuity
1. Disconnect the P/J61 connector from the PWB Drive.
2. Measure the voltage between J61-8 <=> J61-7.
Is there 5V DC between J61-8 <=> J61-7.
Replace the PWB Drive.
(Refer to Ch4-4.2.18.5)
Go to step 10.
10
Harness Assy LVNC (PL15.2.1) continuity
1. Disconnect the P/J165 connector from the LVPS (PL15.1.10).
2. Measure the voltage between P165-1 <=> P165-2.
Is there 5V DC between P165-1 <=> P165-2.
Replace the Harness Assy
LVNC (PL15.2.1).
