Diagnostic Aids

Perform this circuit test when directed by other TESTS. This test is intended to diagnose:

1) Check For Codes 121, 122 & 123  Disconnect cruise control servo. Perform KOEO SELF-TEST. If Code 121, 122 or 123 is present, go to appropriate TEST. See DIAGNOSTIC TROUBLE CODE REFERENCE CHARTS and service codes as necessary. If Code 111 (pass code) is displayed, go to next step. If no code is displayed, go to TEST QA.

2) Check Throttle Linkage  Check throttle and linkage for sticking and binding. If throttle and linkage are okay, replace Throttle Position (TP) sensor and repeat QUICK TEST. If throttle and linkage are binding, repair as necessary and repeat QUICK TEST.
