and all other EN-C8 terminals.
Test Step 3. Test for Shorted Lower
Cab Wiring Harness.
1. Disconnect connector C-C7
(WP 0012, Figure 59) from
transmission neutralizer sensor.
2. Remove left lower cab access
panels (WP 0347).
3. Remove transmission ECM cover
(WP 0266).
4. Disconnect connector C-C12
(WP 0012, Figure 26) from
Transmission ECM J1.
5. Using digital multimeter
Continuity - Replace lower cab wiring

Proceed to Test Step 4.
Test Step 4. Verify Malfunction Is
Resolved.
1. Ensure all wiring harness
connectors are connected.
2. Install right lower cab access
panels (WP 0347).
3. Install transmission ECM cover
(WP 0266).
4. Install left lower cab access panels
(WP 0347).
5. Using MSD, check for active
