John Deere 002358.03: Voltage Detected at Grab Rail Headlight High Beam/Work Light Pin When Headlights/Work Lights Are Off

Voltage is detected at the Grab Rail Headlight High Beam/Work Light pin on the module when the headlights or work lights are turned off. This suggests a voltage back feed in the wiring loom. The affected circuit may be causing unintended voltage presence.

1. 1

   The wiring loom for any signs of damage or short circuits

2. 2

   Connections at the Grab Rail Headlight High Beam/Work Light pin

3. 3

   The Main Control Module (BLC) for abnormal behavior

1. 1

   Inspect the wiring loom

   Check for any physical damage, fraying, or short circuits in the wiring loom that may be causing a voltage back feed.

2. 2

   Verify connections at the Grab Rail Headlight High Beam/Work Light pin

   Ensure that the connections at the specified pin are secure and not causing unintended voltage flow.

3. 3

   Test the Main Control Module (BLC)

   Perform a diagnostic test on the Main Control Module (BLC) to confirm if it is functioning correctly and not contributing to the voltage anomaly.
