21. TCM Self-diagnosis Does Not Activate (PNP & Overdrive Control Switches,
and Throttle Position Sensor Circuit Checks)
ECS004VM
SYMPTOM:
O/D OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION
lPNP switch
The PNP switch assembly includes a transmission position switch. The transmission position switch
detects the selector lever position and sends a signal to the TCM.
lOverdrive control switch
Detects the overdrive control switch position (ON or OFF) and sends a signal to the TCM.
lThrottle position sensor *
*: This sensor means accelerator pedal position (APP) senror.
Electric throttle control actuator consists of throttle control motor, acceleration pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the TCM.

DIAGNOSTIC PROCEDURE
1.CHECK PNP SWITCH CIRCUIT (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out “P/N”, “R”, “D”, “2” and “1” position switches moving selector lever to each position.
Check that the signal of the selector lever position is indicated
properly.
OK or NG
OK >> GOTO3
NG >> Check the following items:
lPNP switch (Refer to “Component Inspection”,AT-
387, "COMPONENT INSPECTION".)
lHarness for short or open between ignition switch and
PNP switch (Main harness)
lHarness for short or open between PNP switch and
TCM (Main harness)
lDiode (P, N positions)
2.CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to “ON” position. (Do not start engine.)
2. Check voltage between TCM terminals 26, 27, 34, 35, 36 and
ground while moving selector lever through each position.
OK or NG
OK >> GOTO4
NG >> Check the following items:
lPNP switch (Refer to “Component Inspection”,AT-
