1
Harness Assy ROS (PL15.2.5) continuity check
1. Disconnect the P/J151 connector from the ROS Assy. (Refer to Ch4-4.2.14.1)
2. Disconnect the P/J15 connector from the PWBA MCU & HVPS. (Refer to Ch4-4.2.18.1)
3. Check the continuity in all lines between J15 <=>J151.
Is the continuity normal between J15 <=> P151?
Go to step 2.
Replace the Harness Assy SOS
(PL15.2.5).
2
PHD Assy (PL11.1.3)
1. Install the new PHD Assy.
2. Turn On the power.
Does the problem still occur?
Go to step 3.
Problem solved.
3
LD 5V DC circuit continuity (1)
1. Disconnect the P/J140 connector from the PWBA MCU & HVPS (PL15.1.2).
2. Check the continuity between P15-6 <=> P140-1.
Is there continuity between P15-6 <=> P140-1?
Go to step 4.
Replace the PWBA MCU &
HVPS. (Refer to Ch4-4.2.18.1)
4
Harness Assy EEPROM (PL15.2.10), Harness Assy CRUM (PL12.3.8) continuity
Check the continuity for the following lines.
J140-1 <=> P71-6/J71-1 <=> J710-6
J140-6 <=> P71-1/J71-6 <=> J710-1
Is there continuity in all lines?
Go to step 5.
Replace the harness with no
continuity.
5
Power supply to 5V DC/24V DC
1. Remove the PHD Assy (PL11.1.3).
2. Measure the voltages at each terminal of the PWB Drive (PL15.1.15).
P/J41-24 <=> P/J41-21/22 (5V DC)
P/J41-17/18 <=> P/J41-19/20 (24V DC when interlock switch is on)
Are the voltages between all terminals at the standard values?
Go to step 6.
Go to step 8.
