1. CHECK PNP SW SIGNALS
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. Change selector lever to “P”, “R”, “N”, “D” and “L” positions to check the value of “INH SW1”“INH SW2”
“INH SW3”“INH SW4” and “INH SW3M”.
Without CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Change selector lever to “P“, “R”, “N”, “D” and “L” positions to
check voltage between the TCM connector terminals and
ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2. CHECK PNP SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
