UNIFIED METER AND A/C AMP
Revision: 2006 November2007 350Z
DTC [U1000] CAN Communication CircuitNKS00072
Symptom: Display CAN COMM CIRC [U1000] at the result of self-diagnosis for unified meter and A/C amp.
1. CHECK CAN COMMUNICATION
1. Select “SELF-DIAG RESULTS” mode for “METER A/C AMP” with CONSULT-III.
>> Go to “LAN system”. Refer to LAN-48, "
CAN System Specification Chart" .
DTC [B2201] Triple Meter Communication CircuitNKS00073
Symptom: Display T/METER COMM CIRC [B2201] at the result of self-diagnosis for unified meter and A/C
amp.
NOTE:
For the wiring diagram, refer to DI-31, "
Wiring Diagram — 3METER —" .
1. CHECK CONNECTOR
Check triple meter, unified meter and A/C amp. and terminals (triple meter side, unified meter and A/C amp.
side, and harness side) for looseness or bent terminals.
OK or NG
OK >> GO TO 2.
NG >> Repair terminal or connector.
2. CHECK METER/GAUGES VISUALLY
Does the pointer on the meter/gauges fluctuate at the engine start?
Is the fluctuation acceptable?
YES >> GO TO 3.
NO >> GO TO 6.
3. CHECK CONTINUITY COMMUNICATION CIRCUIT (TX: TRIPLE METER)
1. Turn ignition switch OFF.
2. Disconnect triple meter connector and unified meter and A/C amp. connector.
3. Check continuity between triple meter harness connector M44
terminal 4 and unified meter and A/C amp. harness connector
M48 terminal 20.
4. Check continuity between triple meter harness connector M44
terminal 4 (P) and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.4 – 20 : Continuity should exist.
4 – Ground : Continuity should not exist.SKIB1172E

DI-52
UNIFIED METER AND A/C AMP
Revision: 2006 November2007 350Z
7. CHECK VOLTAGE OF COMBINATION METER
1. Connect triple meter connector.
2. Turn ignition switch ON.
3. Check voltage between unified meter and A/C amp. harness
connector M48 terminal 10 and ground.
OK or NG
OK >> GO TO 8.
NG >> Replace triple meter.
8. CHECK VOLTAGE SIGNAL OF UNIFIED METER AND A/C AMP.
1. Turn ignition switch OFF.
2. Connect triple meter connector and unified meter and A/C amp. connector.
3. Turn ignition switch ON.
4. Check voltage signal between triple meter harness connector
M44 terminal 5 and ground.
OK or NG
OK >> Replace triple meter.
NG >> Replace unified meter and A/C amp.
DTC [B2202] Meter Communication CircuitNKS00074
Symptom: Display METER COMM CIRC [B2202] at the result of self-diagnosis for unified meter and A/C amp.
NOTE:
For the wiring diagram, refer to DI-11, "
Wiring Diagram — METER —" .
1. CHECK CONNECTOR
Check combination meter, unified meter and A/C amp. and terminals (combination meter side, unified meter
and A/C amp. side, and harness side) for looseness or bent terminals.
OK or NG
OK >> GO TO 2.
NG >> Repair terminal or connector.
2. CHECK METER/GAUGES VISUALLY
Does the pointer on the meter/gauges fluctuate at the engine start?
Is the fluctuation acceptable?
YES >> GO TO 3.
NO >> GO TO 6.10 – Ground : Approx. 5 V
