Honda Pilot: Moonroof Switch Test

Test

1. Roof Console Module - Remove

2. Moonroof Switch - Test

NOTE: The moonroof switch is built into the roof console module (A).

1. Check the switch according to the table.

NOTE:

• When an LED is located between terminals, check if the LED illuminates by connecting power and ground to the LED.
• Note this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).

2. If the result is not as specified, the moonroof switch is faulty; replace the roof console module.

3. All Removed Parts - Install

1. Install the parts in the reverse order of removal.

Multiplex Integrated Control System Sleep and Wake-Up Mode Test

1. Shift to the sleep mode:

Close all doors. Turn the vehicle to the OFF (LOCK) mode, then open and close the driver's door. If the MICU receives no signals from the inputs listed below, it will go into sleep mode in less than 40 seconds.

• IG1 power supply
• IG2 power supply
• B-CAN data
• Hazard warning switch (ON)

2. Confirm sleep mode:

NOTE: Check the official Honda service website for more service information about parasitic draw at the 12 volt battery.

Check the parasitic draw at the 12 volt battery while entering sleep mode; amperage should change from about 200 mA to less than 35 mA in less than 40 seconds.

3. Shift to wake-up mode:

When turning the vehicle to the ON mode, the MICU, the gauge control module, the power window master switch, the keyless access/TPMS control unit, and the PCM will wakeup at the same time without "talking" to each other through the communication lines. When any switch in the multiplex integrated control system is turned on, it wakes up its related control unit which, in turn, wakes up the other units. After confirming the sleep mode, look in the following table for the switch most related to the problem. Operate that switch and see if its control unit wakes up.

NOTE: If any control unit is faulty and does not wake up, several circuits in the system malfunction at the same time. Below is a list of the switches and input signals that wake them up.

• IG1 power supply
• IG2 power supply
• ACC power supply
• B-CAN data
• Driver's door lock switch (LOCK/UNLOCK)
• Front passenger's door lock switch (LOCK/UNLOCK)
• Driver's door switch (Open)
• Front passenger's door switch (Open)
• Left rear door switch (Open)
• Right rear door switch (Open)
• Tailgate latch switch (Open)
• Tailgate open switch (Open)
• Security hood switch (Open)
• Driver's door key cylinder switch (LOCK/UNLOCK)
• Driver's door lock knob switch (LOCK/UNLOCK)
• Front passenger's door lock knob switch (LOCK/UNLOCK)
• Left rear door lock knob switch (UNLOCK)
• Right rear door lock knob switch (UNLOCK)
• Hazard warning switch (ON)
• Combination light switch (Parking, Headlight, Dimmer, Passing)
• Audio security switch (ON)
