A/C and AV Switch Self-Diagnosis FunctionAKS00BMP
It can check ON/OFF operation of each switch in the A/C and AV switch and diagnose the input signals to the
audio steering wheel switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “MUTE/II ” and
“PREV ” simultaneously for 3 seconds.
DIAGNOSIS FUNCTION
The following are checked:
All the indicators (LED) in the A/C and AV switch.
Continuity of the switches by sounding the buzzer when the A/C and AV switch is pressed.
Continuity of harness between A/C and AV switch and audio steering wheel switch.
EXITING THE SELF-DIAGNOSIS MODE
Turn ignition switch OFF.
Trouble DiagnosisAKS00BMQ
The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic
interference, etc.). Check the symptoms below to diagnose the malfunction.
MALFUNCTION WITH RADIO, TAPE AND CD (BASE SYSTEM)
Make sure that operation excepting audio system can be done with A/C and AV switch. If not, refer AV- 8 4 , "A/
C and AV Switch Does Not Operate" to repair malfunctioning parts.

BCM (BODY CONTROL MODULE)
Revision: 2004 November 2004 FX35/FX45
BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
With ignition switch ON, CAN communicates with other control units normally.
Control by BCM is being operated properly.
When ignition switch is OFF, switching to sleep mode is possible.
Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status
This status shuts down CAN communication when ignition switch is turned OFF.
It transmits sleep request signal to IPDM E/R and combination meter.
Two seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status
With ignition switch OFF, CAN communication is not active.
With ignition switch OFF, control performed only by BCM is active.
Three seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status
BCM is activated with low current consumption mode.
CAN communication is not active.
When CAN communication operation is detected, it switches to CAN communication status.
When a state of the following switches changes, it switches to CAN communication state.
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH)
–Back door opener switch
–Combination switch (passing, lighting switch 1st position, Front fog lamp)
–Key fob (lock/unlock signal)
–Key cylinder switch
When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
Status of combination switch reading function is changed.
