DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

With CONSULT
1. Turn ignition switch "ON".








2. Select "DATA MONITOR" mode for "ENGINE" with CONSULT.
3. Start engine and maintain the following conditions for at least 5 consecutive seconds.
VEHICLE SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: More than 1.3V
Selector lever: D position (OD "ON" or "OFF")

With GST
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in "D" position, overdrive control switch in "ON" or "OFF" position, vehicle speed higher than 10 km/h (6 MPH), throttle position sensor more than 1.3V and driving for more than 5 seconds.
3. Select "MODE 7" with GST

With No Tools
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in "D" position, overdrive control switch in "ON" or "OFF" position, vehicle speed higher than 10 km/h (6 MPH), throttle opening greater than 1/2 of the full throttle position and driving for more than 5 seconds.

DIAGNOSTIC PROCEDURE











COMPONENT INSPECTION
PARK/NEUTRAL POSITION (PNP) SWITCH











1. Check continuity between terminals 1 and 2 and between terminals 3 and 4, 5, 6, 7, 8, 9 while moving manual shaft through each position.





2. If NG, check again with manual control linkage disconnected from manual shaft of A/T assembly. Refer to step 1.
3. If OK on step 2, adjust manual control linkage.





4. If NG on step 2, remove park/neutral position (PNP) switch from A/T and check continuity of park/neutral position (PNP) switch terminals. Refer to step 1.
5. If OK on step 4, adjust park/neutral position (PNP) switch.
6. If NG on step 4, replace park/neutral position (PNP) switch.
Refer to Transmission Control Systems.
