4. Check parking brake switch operation.
1. If resistance from contact N/C (wire
0070 04 -
(a) Wiring harness remains disconnected
E417 OR) to contact N/O (wire F765
from parking brake switch.
BR) is less than 5.0 Ohms, and
(b) Press and hold parking brake switch.
resistance from contact N/C (wire
E417 OR) to contact J1-13 (wire 202
contact N/C (wire E417 OR) and other
BK) is greater than 5,000 Ohms, go to
lead to contact N/O (wire F765 BR) of

5. Verify diagnostic code remains active.
1. If CID 0070 FMI 04 is active,
(a) Inspect and clean harness connector

Replace machine ECM (WP 0052 00).
(b) Reconnect all harness connectors.
