F336 Fuel Pull-In Relay - Low Current

Usage:

45 3BK



Illustration 1g00564053

(1) Chassis Control Module (CCM). (2) Fuel Pull-in Relay (MDP-R16). (3) Fuel Solenoid.

This fault code indicates the fuel pull-in relay output circuit has a lower than normal current and may be due to an open circuit or missing relay.

  1. Visually inspect fuel pull-in relay, relay socket, Cab Main harness and connector C006 for frayed wires, pulled connector terminals, broken or damaged parts.

    Expected Result: There is damaged parts or broken parts.

    • YES, repair damaged parts as appropriate, reconnect connectors and recheck fault codes. If fault code is not active, repair is complete.

    • NO, go to Step 2.

  1. Unplug fuel pull-in relay at MDP-R16. Replace the relay with another relay from the MDP or new part.

    Expected Result: The fault code clears.

    • YES, replace fuel pull-In relay and recheck fault codes. If fault code is not active, repair is complete.

    • NO, go to Step 3.

  1. Check for open circuit in Cab Main harness between terminals C006-1 and MDP-R16 terminal 85.

    Expected Result: There is an open in the circuit.

    • YES, locate and repair open circuit in Cab Main harness. Check fault code and if no longer active the repair is complete.

    • NO, go to Step 4.

  1. Check for open circuit in Cab Main harness between terminal 86 of MDP-R16 and chassis ground.

    Expected Result: There is an open in the circuit.

    • YES, locate and repair open circuit in Cab Main harness. Check fault code and if no longer active the repair is complete.

    • NO, go to Step 5.

  1. Download latest control module software into all control modules.

    Expected Result: The fault code is active.

    • YES, go to Step 6.

    • NO, repair is complete. Calibrate transmission and three-point hitch.

  1. Replace the Chassis Control Module (CCM).

    Expected Result: The fault code is active.

    • YES, install the original CCM and repeat this troubleshooting procedure.

    • NO, go to Step 7.

  1. Install the original CCM.

    Expected Result: The fault code is active.

    • YES, original CCM was faulty. Replace original CCM with new CCM. If fault code is not active, repair is complete. Download latest control module software into all modules. Calibrate transmission and three-point hitch.

    • NO, this fault code may have been caused by faulty connectors. Keep the original on the tractor. Clean all terminals on the CCM and reconnect. If fault code is not active, repair is complete. Download latest control module software into all modules. Calibrate transmission and three-point hitch.
