This test procedure may create other diagnostic codes. Ignore these created diag-
nostic codes and clear these diagnostic codes when original diagnostic code has
been corrected. Ensure diagnostic code CID 0271 FMI 05 is active before per-
forming this procedure.
1. Check alarm.
1. If diagnostic code remains active, go to
(a) Turn battery disconnect switch and
engine start switch to ON position. Do 2. If diagnostic code is no longer active,
repeat this test to verify alarm failure.
(b) Disconnect alarm from wiring harness.
Replace alarm (WP 0051 00). Verify
