DIAGNOSTIC ROUTINES - SOME/ALL SHIFTS MISSING

Possible Component	Reference/Action
210 - ROUTINE
Powertrain Control System	CARRY OUT On-Board Diagnostic (OBD) tests. REFER to the INTRODUCTION article for diagnosis and testing of the PCM and APP sensor. For diagnosing SSPCA , SSPCB , SSPCC , SSPCD and SSPCE , GO to PINPOINT TEST A . For diagnosing TFT sensor, GO to PINPOINT TEST B . For diagnosing TR sensor, GO to PINPOINT TEST C . For diagnosing TSS /intermediate shaft speed sensor, GO to PINPOINT TEST D . For diagnosing PCA , GO to PINPOINT TEST E . REPAIR as necessary. CLEAR the DTCs, ROAD TEST the vehicle and RERUN the OBD test.
