Step
Possible causative parts:
HARN ASSY R SIDE (PL10.1.15)
PWBA EEPROM (PL9.1.1)
PWBA MCU (PL9.1.20)
Does Error still occur after several ON/OFF procedures of
1
the power?
Checking the firmware version
2
Does the firmware is the latest version?
Checking after reseating the PWBA MCU
3 Reseat the PWBA MCU.
Does Error still occur when the power is turned ON?
Checking the connectors for connection
Check the connections between the PWBA EEPROM and
4
PWBA MCU.
Are P/J28 and P/J144 connected surely?
5 Does the error still occur when the power is turned ON?
Checking the HARN ASSY R SIDE for continuity
Disconnect P/J28 form the PWBA MCU.
6
Disconnect P/J144 from the PWBA EEPROM.
Is each cable of P/J28 <=> P/J144 continuous?
Checking the power to PWBA EEPROM
Disconnect P/J28 on the PWBA MCU.
7
Is the voltage across ground <=> J28-16pin on the PWBA
MCU, about +3.3 VDC?
Checking after replacing the PWBA MCU
Replace the PWBA MCU. (Refer to Removal 30/Replace-
