PROCEDURE
1.CHECK HARNESS AND CONNECTOR (COMPRESSOR ASSEMBLY WITH PULLEY - AIR CONDITIONING AMPLIFIER ASSEMBLY)
a.
Disconnect the I49 air conditioning amplifier assembly connector.
b.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition C84-2 (SOL+) - I49-18 (SOL+) Always Below 1 Ω C84-2 (SOL+) or I49-18 (SOL+) - Other terminals and body ground Always 10 kΩ or higher
- Result:
Proceed to OK NG
OK
