YES >> Check CAN communication line. Refer to TM-39. U1000
NO >> GO TO 2.
2. CHECK DTC WITH TCM
With CONSULT-III
1. Turn ignition switch "ON". (Do not start engine.)
2. Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
3. Depress accelerator pedal and read out the value of "ACCELE POSI".
4. Select "SELF-DIAG RESULTS" mode for "TRANSMISSION" with CONSULT-III. Refer to TM-33, "CONSULT-III Function (TRANSMISSION)". Scan Tool Testing and Procedures
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK DTC WITH ECM
With CONSULT-III
1. Turn ignition switch "ON". (Do not start engine.)
2. Select "SELF-DIAG RESULTS" mode for "ENGINE" with CONSULT-III. Refer to TM-33, "CONSULT-III Function (TRANSMISSION)". Scan Tool Testing and Procedures
