Dtc 30106 Cancomm - Yale 524150797 Maintenance Manual

ELECTRICAL SYSTEM
POSSIBLE CAUSE
A. CANBUS COMMUNICATION FAULT
B. TILLER CARD WIRING FAULT
C. FAULTY HANDLE
COMPONENT OPERATIONAL CHECK
NOTE: Always check battery condition and state of charge before performing electrical troubleshooting. A faulty
or low charged battery will cause electrical features to not operate as designed and give incorrect readings while
performing electrical tests.
PROCEDURE OR ACTION:
1. Conduct a visual inspection of all connectors/wiring associated with the fault code.
Are any faults detected/observed?
YES: Repair/replace connector or wiring associated with faults found. Refer to the appropriate Electrical
System YRM .
NO: Proceed to Step 2.
2. Re-key the vehicle.
Is the code still present?
YES: Proceed to Step 3.
NO: Problem may be intermittent.
3. Perform multiplexing checks, see the Multiplexing Section.
Are any CANbus circuit faults present?
YES: Repair and retest system.
NO: Proceed to Step 4.
4. Measure resistance between frame and CANbus circuits.
Is resistance ≥1M ohm?
YES: Proceed to Cause A.
NO: Suspect short to frame.
CAUSE A - CANBUS COMMUNICATION FAULT
PROCEDURE OR ACTION:
NOTE: Perform Step 1 and Step 2 with key in ON position.
NOTE: Connector CJ2 is an eight position connector.
1. Disconnect the tiller card connector CJ2 and measure voltage between connector CJ2, socket 2 and B(-).
Is CAN HI voltage approximately 2.5 Vdc?
YES: Proceed to Step 2.
NO: Inspect CAN HI circuit for open or short. If voltage is 0 volts, the CAN HI circuit is shorted to ground or
open. If voltage is above 5 volts, the CAN HI circuit is shorted to power.
2. Measure voltage between the tiller card connector CJ2, socket 1 and B(-).
Is CAN LO voltage approximately 2.5 Vdc?
