Diagnostic Procedure for Sensors
Step Check Yes No
1 CHECK HARNESS CONNECTOR BETWEEN
AUTO A/C CONTROL MODULE AND COM-
BINATION METER.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from auto A/C
control module and combination meter.
3) Measure the resistance in harness
between auto A/C control module and combi-
nation meter.
Connector & terminal
(i10) No. 30 — (i48) No. 14:Is the resistance less than 1
Ω?Go to step 2.Repair the har-
ness between auto
A/C control mod-
ule and combina-
tion meter.
2 CHECK AMBIENT SENSOR CIRCUIT.
Check the ambient sensor circuit. 8, CHECK OUTSIDE TEMPERATURE INDI-
CATOR, INSPECTION, Combination Meter
System.>Is the ambient sensor circuit
normal?Go to step 3.Repair the ambi-
ent sensor circuit.
3 CHECK POOR CONTACT.
Check poor contact in auto A/C control module
connector.Is there poor contact in con-
nector?Repair the con-
nector.Replace the A/C
control module.
