Description
RETAINED PWR
This test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in OFF position. “RETAINED
PWR” should be turned ON or OFF on CONSULT-III screen when ignition switch is ON. Then turn
ignition switch OFF to check retained power operation. CONSULT-III might be stuck if “RETAINED
PWR” is turned to ON or OFF on CONSULT-III screen when ignition switch is OFF.
