22C-165

MONITOR EXECUTION CONDITIONS 
(OTHER MONITOR AND SENSOR)

Other Monitor (There is no temporary DTC stored 

in memory for the item monitored below)

• P1836: Shift fork 1 malfunction

• P184B: Shift fork 4 malfunction

Sensor (The sensor below is determined to be 

normal)

• Not applicable

.

DTC SET CONDITIONS <FUNCTIONAL 
CHECK - BLOCKED>

Check Conditions

• Voltage of battery: 8 V or more.

• Voltage of battery: 16.5 V or less.

• Engine speed: 500 r/min or more.

• Time since above engine condition: 400 millisec-

ond or more.

• Common high side 1 voltage: 2.5 V or more.

• Common high side 2 voltage: 2.5 V or more.

JUDGMENT CRITERIA

•

• Shift fork operation time: Shift fork operation time 

(threshold value) or more. (immediately)

• Shift fork operation time (threshold value): Equal 

the maximum allowed time x Coefficient. (imme-
diately)

.

OBD-II DRIVE CYCLE PATTERN 
<FUNCTIONAL CHECK - BLOCKED>

The shift fork operation time is threshold value or 
less.

DTC SET CONDITIONS <FUNCTIONAL 
CHECK - 6TH GEAR>

Check Conditions

• Voltage of battery: 8 V or more.

• Voltage of battery: 16.5 V or less.

• Engine speed: 500 r/min or more.

• Time since above engine condition: 400 millisec-

ond or more.

• Shift fork 3 current gear: 6th gear.

JUDGMENT CRITERIA

• Shift fork position: −6 mm (−0.24 inch) or more, 

and input shaft 2 (even) speed: 500 r/min or 
more, or synchro (6th gear) slip speed: 80 r/min 
or more. (400 millisecond)

.

OBD-II DRIVE CYCLE PATTERN
