1.CHECK THERMAL TRANSMITTER
Refer to DI-22, "
THERMAL TRANSMITTER CHECK" .
OK or NG
OK >> GO TO 2.
NG >> Replace thermal transmitter.
2.CHECK HARNESS FOR OPEN OR SHORT
1. Disconnect combination meter connector and thermal transmit-
ter connector.
2. Check continuity between combination meter harness connector
M46 terminal 55 (PU/W) and thermal transmitter harness con-
nector F23 terminal 1 (PU/W).
3. Check continuity between combination meter harness connector
M46 terminal 55 (PU/W) and ground.
OK or NG
OK >> Thermal transmitter is OK.
NG >> Replace harness or connector.Continuity should exist.
Continuity should not exist.
