CONSULT-III display Malfunction Reference page
CAN COMM CIRC [U1000] Malfunction is detected in CAN communication lines.
CAUTION:
Even when there is no malfunct ion on CAN communication system, mal-
function may be misinterpreted when battery has low voltage (when main-
taining 7 - 8 V for about 2 seconds) or 10A fuse [No. 14, located in the fuse
block (J/B)] is removed. DI-18VEHICLE SPEED CIRC [B2205]
Malfunction is detected when an erroneous speed signal is input.
CAUTION:
Even when there is no malfunction on speed signal system, malfunctions
may be misinterpreted when battery has low voltage (when maintaining 7
- 8 V for about 2 seconds). DI-15Display item [Unit]

• through grounds E15 and E24.
HEADLAMP OPERATION
Low Beam Operation With the lighting switch in 2ND position, the BCM re ceives an input signal requesting the headlamps to illumi-
nate. The BCM then sends a signal, via the CAN comm unication lines, to the IPDM E/R requesting the low
beam headlamps be turned ON. The CPU located in the IPDM E/R controls ground to the headlamp low relay
coil, which when energized, directs power
• through 15A fuse (No. 41, located in IPDM E/R)
• through IPDM E/R terminal 54
• to headlamp RH terminal 3, and
• through 15A fuse (No. 40, located in IPDM E/R)
• through IPDM E/R terminal 52
• to headlamp LH terminal 3.
Ground is supplied
• to headlamp RH and LH terminals 2
• through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation With the lighting switch in 2ND position and high beam s witch in the HIGH position, the BCM receives an input
signal requesting the headlamp high beams to illuminate. The flash to pass feature can be used any time and
also sends a signal to the BCM. This input signal is then communicated to the IPDM E/R and the combination
meter via the CAN communication. The CPU located in the IPDM E/R controls the headlamp high relays (LH
and RH), which when energized, directs power
• through 10A fuse (No. 34, located in IPDM E/R)
• through IPDM E/R terminal 56
• to headlamp RH terminal 1, and
• through 10A fuse (No. 35, located in IPDM E/R)
• through IPDM E/R terminal 55
• to headlamp LH terminal 1.
Ground is supplied
• to headlamp RH and LH terminal 2
• through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal, via the CAN communication lines, to the combination meter requesting the high
beam indicator lamp be turned ON.
