Schematic of the Right Front Brake Oil Temperature Sensor
This diagnostic code is recorded when the VIMS electronic control module reads the signal and the frequency of the signal or pulse of the signal is not within an expected range. The possible causes of this failure are listed below:
The sensor has failed.
There are intermittent connections of the machine harness.
There are poor connections of the machine harness.
There are loose mechanical connections.
There is electro-magnetic interference.
The VIMS electronic control module has failed.System Response:This failure causes the right front brake oil temperature sensor to indicate the maximum temperature or this failure causes the right front brake oil temperature sensor to intermittently indicate the maximum temperature. Note: The “Sensor Voltage Test” within the topic “Pulse Width Modulated (PWM) Sensor - Test” also covers the troubleshooting of a failed sensor.Test Step 1. CHECK THE ELECTRONIC CONTROL MODULE AND THE MACHINE HARNESS.
Turn the disconnect switch and the key start switch to the "ON" position.
Disconnect the machine harness from the sensor.
At the machine harness connector for the sensor, measure the voltage between the signal contact C (wire F433-PU(Purple)) and the ground contact B (wire J842-BK(Black)). Expected Result:The voltage is 5.0 0.5 DCV. Results:
OK - The voltage is 5.0 0.5 DCV. The VIMS electronic control module and the machine harness are correct. Repair: The sensor has failed. Perform the Testing and Adjusting, "Pulse Width Modulated (PWM) Sensor - Test" procedure prior to rplacing the sensor.STOP
NOT OK - The voltage is NOT 5.0 0.5 DCV. The VIMS electronic control module or the machine harness have failed. Proceed to test step 2.Test Step 2. CHECK THE GROUND CIRCUIT OF THE MACHINE HARNESS.
The sensor remains disconnected.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect J1 and J2 machine harness connectors from the VIMS electronic control module.
At the machine harness connector for the sensor, measure the resistance between ground contact B (wire J842-BK(Black)) and connector contact J2-19 (wire J842-BK(Black)). Expected Result:The resistance is less than 5.0 ohms. Results:
OK - The resistance is less than 5.0
