The following test procedure may create other diagnostic codes. Ignore
these created diagnostic codes and clear these diagnostic codes when the
original diagnostic code is corrected. Ensure diagnostic code CID 2684
FMI 05 is active before performing this procedure.
1. Check solenoid.
(a) Turn battery disconnect and engine
start switches to ON position. Do not
start engine (TM 5-3805-291-10).
(b) Disconnect ride control solenoid valve
#3 from wiring harness (WP 0218 00).
(c) At wiring harness connector for
solenoid, place a jumper wire from
contact 2 to contact 1.
(d) Connect MSD (WP 0005 00) and
1. If diagnostic code remains active, go
observe status of CID 2684 FMI 05.
Test 2.
2. If diagnostic code is no longer active,
solenoid has failed. Repeat this test to
verify solenoid failure. Replace main
control valve (WP 0218 00). Verify new
solenoid corrects problem.
2. Check wiring harness for an open circuit.
(a) Turn engine start and battery
disconnect switches to OFF position
(TM 5-3805-291-10).
