GENERAL SERVICE DIAGNOSIS
Service Diagnosis Charts
Two service diagnosis charts are provided. The
first chart covers in-vehicle diagnosis proce-
dures. The second chart covers out-of vehicle
diagnosis procedures.
The Condition columns in each chart describe
the most frequently encountered malfunctions.
Each problem condition is cross-referenced to
the necessary service procedures.
Code letters in the boxes at the top of each
chart identify the service procedures. These let-
ters correspond to procedure descriptions that
follow the charts.
Capital letters A through T denote In-Vehicle
Procedures. Lower case letters a through j de-
note Out-Of-Vehicle Procedures.
As an example, assume the problem is Harsh
Engagement in R-D-2-1. Locate the description
in the Condition column. Then note which pro-
cedures are indicated. Procedures B, D, E, G,
N, Q are required as shown in the chart. Note
the numbers indicating the sequence in which
these procedures are to be performed. In this
case, the correct order would be D, B, E, G, Q,
N.
