AUTOMATIC TRANSAXLE DIAGNOSIS

TSB Revision

AUTOMATIC TRANSAXLE

23A-124

.

CIRCUIT OPERATION

• Battery positive voltage is applied to the transmis-

sion range switch (terminal 8) when the ignition 
switch is turned "ON."

• Battery positive voltage is applied to the PCM 

(terminal 67) when the transmission range is in 
the "P" range. The PCM judges that the transmis-
sion range is in the "P" range when the battery 
positive voltage is applied.

• Battery positive voltage is applied to the PCM ter-

minal 61 (77, 73, 62, 75 or 72) when the selector 
lever is in the "R" range ("N," "D," "3," "2" or "L" 
range). The PCM judges that the selector lever is 
in the "R" range ("N," "D," "3," "2" or "L" range) 
when the battery positive voltage is applied.

.

DESCRIPTIONS OF MONITOR METHODS

• If no signal is input from transmission range 

switch for more than 30 seconds, PCM judges 
that transmission range switch has a failure.

.

MONITOR EXECUTION

• Continuous

DTC SET CONDITIONS

Check Conditions, Judgement Criteria

• Transmission range switch: no signal detected. 

(30 seconds)

.

OBD-II DRIVE CYCLE PATTERN
Start the engine, keep the vehicle stopped in "P," "R," 
"N," "D," "3," "2" and "L" ranges respectively for more 
than one minute, and turn "LOCK" (OFF) the ignition 
switch. Then restart the engine, and stop the vehicle 
in "P," "R," "N," "D," "3," "2" and "L" ranges respec-
tively for more than one minute.

.

TROUBLESHOOTING HINTS (The most likely 
causes for this code to be set are:)

• Malfunction of the transmission range switch

• Malfunction of the ignition switch

• Damaged harness or connector

• Malfunction of the PCM

DIAGNOSIS

Required Special Tool:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: MUT-III USB Cable

• MB991910: MUT-III Main Harness A

AUTOMATIC TRANSAXLE

23A-126

STEP 1. Using scan tool MB991958, check data list item 61: 
Transmission Range Switch.

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to "ON" position.

(3) Set scan tool MB991958 to the data reading mode.

• Item 61: Transmission Range Switch.

• Move the selector lever to "P," "R," "N," "D," "3," "2," 

"L" and sport mode positions and confirm that the 
selected transmission range match the positions 
shown on scan tool MB991958. (Vehicles with sport 
mode is indicated as "D" on the scan tool).

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Does the scan tool indication correspond to the actual 

transmission range?
YES : It can be assumed that this malfunction is intermittent. 

Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction
