Compressor clutch under current (open circuit)

This Diagnostic code indicates that the current in the compressor clutch circuit is <0.5A. This condition is the result of an open, or a high resistance, in the compressor clutch circuit.

Refer to AC COMPRESSOR CIRCUITS .

611 14 9 2

Compressor clutch over current (short circuit)

This Diagnostic code is the result of a short to ground in the compressor clutch circuit or a short across the compressor clutch solenoid.

Refer to AC COMPRESSOR CIRCUITS .

611 14 9 3

Compressor clutch current, higher than open circuit level, but lower than normal low current level

This Diagnostic code is the result of one or more high resistance connections in the compressor clutch or in the clutch circuit current path.

Refer to AC COMPRESSOR CIRCUITS .

611 14 9 4

Compressor clutch current, lower than fusing level, but higher than normal high current level

This Diagnostic code is the result of less than normal resistance in the compressor clutch circuit (probably due to shorted windings in the compressor clutch solenoid).

Refer to AC COMPRESSOR CIRCUITS .
