solenoid, place a jumper wire from
contact 2 to contact 1.
1. If diagnostic code remains active, go to
observe status of CID 2129 FMI 03.
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 If diagnostic code is no longer active,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 solenoid energizer circuit for a short
to +battery circuit.
(a) Turn engine start and battery
disconnect switches to OFF position
(b) Ride control solenoid valve #1 remains
disconnected from wiring harness (WP
(c) Disconnect wiring harness
connector(s) from powertrain ECM

between J2-5 and circuit with low
resistance measurement. Replace
wiring harness in question (WP 0195 00
thru WP 0201 00).
3. Check if diagnostic code remains active.
(a) Inspect and clean wiring harness
(b) Reconnect all harness connectors.
