NOTE

To determine correct test point of large connector, check location of single black wire at connector of

chassis wiring harness.

(a)

Apply 24 VDC to test point of large connector (1) and ring terminal of small black wire (3) of relay (5).

Listen for "click" when voltage is applied. If no "click" is heard, replace relay (5) (perform Removal and

(b)

Installation sections of this paragraph).

(6)

Test emergency steering pump relay (5) for continuity.

(a)

Again, apply 24 VDC to test point of large connector (1) and ring terminal of small black wire (3) of relay

(5).

(b)

Connect multimeter across two terminal studs of relay (5). Multimeter should show continuity.

Remove 24 VDC. Multimeter should show NO continuity.

(c)

If continuity requirements are NOT met in steps (6)(b) and (6)(c), replace relay (5) (perform Removal and

(7)

Installation sections of this paragraph).

(8)

If continuity requirements are met, perform steps (9) through (12).

(9)

Install large red position battery cable (4) and two new lockwashers (11) and nuts (10) to relay (5).

(10) Install ring terminal of small black wire (3) and large black ground cable (2) to negative terminal stud of

emergency steering pump (9) with nut (8).

(11) Connect large connector (1) of relay (5) to connector (6) of chassis wiring harness.

(12) Connect negative battery cable (para 8-44).
