1. Remove jumper wire from terminal
High - Continued
C and terminal B of connector EN-
C7 (WP 0012, Figure 60).
2. Remove right lower cab access
panels (WP 0347).
3. Disconnect connector EN-C2
(WP 0012, Figure 12) from
connector C-C18 (WP 0012,

Proceed to Test Step 6.
Test Step 6. Verify Malfunction Is
Resolved.
1. Ensure all harness connectors are
connected.
2. Install transmission ECM cover
(WP 0266).
3. Install left and right lower cab
access panels (WP 0347).
