Troubleshooting Guide [Without CATA] (continued)
6-17spec tableRight-hand continuation of the Without CATA troubleshooting matrix. The Without CATA version uses an IMA Sensor (page 50) column.
NOTE
Continuation (right-hand half) of the Troubleshooting Guide [Without CATA] chart begun on page 6-16. Symptom rows align with the same symptoms in the left-hand half. Numbers in cells give the inspection order; the page number atop each column points to the relevant inspection procedure.
