6. Measure the resistance from
1. If resistance is greater than 10
the positive (+) battery terminal
Ω, replace engine interface
post lead to engine interface
wiring harness (WP 0388, Vol
wiring harness connector W16
2).
J3 pin 1 (WP 0443, Vol 3 and
WP 0448, Vol 3, Figure 12).
2. If resistance is less than 10 Ω,
go to next test.
7. Measure the resistance from
1. If resistance is greater than 10
the positive (+) battery terminal
Ω, repair or replace engine

J3 pin 2 (WP 0443, Vol 3 and
WP 0448, Vol 3, Figure 12).
2. If resistance is less than 10 Ω,
go to next test.
8. Disconnect engine interface
wiring harness from the battery
positive (+) connector.
9. Measure the resistance from
