PROCEDURE
1. INSPECT COOLING FAN MOTOR
(a) Check that the motor operates smoothly when the battery is connected to the cooling fan motor connector. Text in Illustration
If the motor does not operate smoothly, replace the cooling fan motor. |

11.8 to 14.8 A at 12 V |
Cooling fan motor (w/ Towing package) |
20°C (68°F) |
7.9 to 10.9 A at 12 V |
If the result is not as specified, replace the cooling fan motor.
2. INSPECT NO. 2 COOLING FAN MOTOR
(a) Check that the motor operates smoothly when the battery is connected to the No. 2 cooling fan motor connector. Text in Illustration
If the motor does not operate smoothly, replace the No. 2 cooling fan motor. |

Compressor Lock Sensor Circuit (B1422/22)
SYSTEM DESCRIPTION
The ECM sends the engine speed signal to the A/C amplifier via CAN communication.
The A/C amplifier reads the difference between compressor speed and engine speed.
When the difference becomes too large, the A/C amplifier determines that ...
