Code Description
Code 13C! indicates a relay problem. Likely causes are either a blown
VBATT fuse, the relay itself, or problems with the relay enable circuit.
After checking the VBATT fuse, an easy second step is to swap a known
good relay and see if the fault is cleared. If the fuse, the relay, and the
relay enable circuit all check out OK, the likely cause of the problem is a
faulty Electronic Control Unit (ECU).
See “Troubleshooting Tips” on page 20 for general guidelines on system
diagnostics.
