DTC U1000 CAN COMM CIRCUITINFOID:0000000001327690
INSPECTION PROCEDURE
1.CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect the ABS actuat or and electric unit (control unit) connector, and check
the terminal for deformation, disconnection, looseness, and so on. If there is a malfunction, repair or
replace the terminal.
2. Reconnect connector to perform self-diagnosis.
Is
“CAN COMM CIRCUIT” or “ST ANG SEN COM CIR” displayed in the self-diagnosis display items?
YES >> Print out the self-diagnostic results, and refer to LAN-43, "CAN System Specification Chart".
NO >> Connector terminal connection is loose, damaged, open, or shorted.
Component InspectionINFOID:0000000001327691
VDC OFF SWITCH
 Turn ignition switch OFF and disconnect VDC OFF switch connec- tor, and check continuity betw een VDC OFF switch connector M32
terminals 1 and 2.
1 -2 : Continuity should exist when pushing
switch.
Continuity should not exist when releasing
switch.

UNIFIED METER CONTROL UNIT
 Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the comb ination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.
 Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified meter and A/C amp.
 Odo/trip meter, A/T indicator and ICC system disp lay segments can be checked in self-diagnosis mode.
 Meters/gauges can be checked in self-diagnosis mode.
UNIFIED METER AND A/C AMP.
Refer to DI-26, "System Description" in “UNIFIED METER AND A/C AMP”.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
 through 10A fuse [No. 19, located in the fuse block (J/B)]
 to combination meter terminal 8, and
 to unified meter and A/C amp. terminal 21.
With the ignition switch in the ON or START position, power is supplied
 through 10A fuse [No. 14, located in the fuse block (J/B)]
 to combination meter terminal 7,
 through 10A fuse [No. 12, located in the fuse block (J/B)]
 to unified meter and A/C amp. terminal 22.
With the ignition switch in the ACC or ON position, power is supplied
 through 10A fuse [No. 6, located in the fuse block (J/B)]
 to combination meter terminal 4,
 through 15A fuse [No. 10, located in the fuse block (J/B)], and
 through 15A fuse [No. 11, located in the fuse block (J/B)]
 to unified meter and A/C amp. terminal 46.
Ground is supplied
 to combination meter terminals 5, 6 and 15
 through grounds M35, M45 and M85,
 to unified meter and A/C amp. terminals 29 and 30
 through grounds M35, M45 and M85.
SPEEDOMETER
The speedometer indicates the vehicle speed.
 ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. converts the vehicle s peed signal to the 8-pulse signal, and outputs the vehicle
speed signal (8-pulse) to combination meter.
 Combination meter indicates the vehicle speed according to vehicle speed signal (8-pulse) signal.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
 ECM provides engine speed signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.

 If trip reset switch is pressed for 1 second or more while “trip A” is displayed, only “trip A” is reset.
NOTE:
The record of the odo meter is kept even if the battery cable is dis-
connected. The record of the trip meter is erased when the battery
cable is disconnected.
COMBINATION METER ILLUMINATION CONTROL
Daytime Mode
When ignition switch is turned ON, combination meter il lumination is turned ON by unified meter control unit.
Nighttime Mode
 Unified meter control unit is transferred to nighttime mode, with ignitio\

 When nighttime mode, illumination c ontrol switch illumination turns
ON by unified meter control unit. Each illumination is controlled by
unified meter control unit.
 Each illumination can be adjusted to 16 step by illumination control switch in nighttime mode.
