The following test procedure may create other diagnostic codes. Ignore
these diagnostic codes and clear the diagnostic codes when original diag-
nostic code is corrected. Ensure diagnostic code CID 1406 FMI 06 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) Connect MSD (WP 0005 00) and
Observe status of the diagnostic code.
1. If CID 1406 FMI 06 changes to CID
(c) Disconnect solenoid with active
1406 FMI 05 when solenoid is
diagnostic code from wiring harness
disconnected, repeat this test to verify
(WP 0203 00).
solenoid failure. Replace modulating
valve with active code (WP 0203 00).
Verify new solenoid corrects problem.
2. If CID 1406 FMI 06 remains active, go
to Test 2.
2. Check solenoid energizer circuit for a short
to ground.
(a) Turn engine start and battery
disconnect switches to OFF position
(TM 5-3805-291-10).
(b) Solenoid remains disconnected from
wiring harness.
(c) Disconnect wiring harness
connector(s) from powertrain ECM
(WP 0063 00).
