Step
Checking the connector for connection
Check the connectors between the PWBA MCU and TNR
(Y/M/C/K) MOT (MOTOR ASSY DISP).
Are P/J18, P/J19, P/J181, P/J182, P/J191 and P/J192
connected correctly?

15 Is the image printed correctly?
Checking the HARN ASSY TNR MOT for continuity
Disconnect J18 and J19 from the PWBA MCU.
Disconnect J181, J182, J191 and J192 from the TNR (Y/M/
16
C/K) MOT.
Is each cable of J18 <=> J181 and J182 continuous?
Is each cable of J19 <=> J191 and J192 continuous?
Checking the power to TNR (Y/M/C/K) MOT (MOTOR
ASSY DISP)
Disconnect J18 and J19 from the PWBA MCU.
17 Is the voltage across P18-3pin, P18-8pin, P19-4pin and
P19-9pin <= > ground on PWBA MCU, about +24 VDC
when the interlock switch (HARN ASSY INTERLOCK) is
pushed.
Checking the ROS ASSY for connection
Check the connections between the ROS ASSY and PWBA
MCU.
Are P/J40, P/J 41, P/J411 and P/J 412 connected correctly?
