A/T P Indicator Circuit

DESCRIPTION

The propeller shaft and wheels are free even when the transmission shift lever is on P, as long as the transfer shift lever is on N. The A/T P indicator illuminates to warn the driver that the propeller shaft and wheels are not locked.

If the A/T P indicator illuminates, the transfer shift lever should be moved from N.

INSPECTION PROCEDURE

PROCEDURE

INSPECT PARK/NEUTRAL POSITION SWITCH

Disconnect the N1 park/neutral position switch connector.

Measure the resistance of the park/neutral position switch when the shift lever is moved to each position.

Standard resistance

Tester Connection	Shift Lever Position	Specified Condition
4 (B) - 5 (L)	P or N	Below 1 Ω
4 (B) - 5 (L)	Not on P or N	10 kΩ or higher
1 (RL) - 2 (RB)	R	Below 1 Ω
1 (RL) - 2 (RB)	Not on R	10 kΩ or higher
2 (RB) - 7 (DL)	D	Below 1 Ω
2 (RB) - 7 (DL)	Not on D	10 kΩ or higher
2 (RB) - 3 (2L)	2	Below 1 Ω
2 (RB) - 3 (2L)	Not on 2	10 kΩ or higher
2 (RB) - 8 (LL)	L	Below 1 Ω
2 (RB) - 8 (LL)	Not on L	10 kΩ or higher

REPLACE PARK/NEUTRAL POSITION SWITCH

OK

INSPECT NO. 2 TRANSFER INDICATOR SWITCH (TRANSFER NEUTRAL POSITION SWITCH)

Remove the transfer indicator switch.

Measure the resistance of the switch when pushing the ball at the tip of the switch.

Standard resistance

Tester Connection	Switch Condition	Specified Condition
1 - 2	Not pushed	10 kΩ or higher
1 - 2	Pushed	Below 1 Ω

NG

REPLACE NO. 2 TRANSFER INDICATOR SWITCH (TRANSFER NEUTRAL POSITION SWITCH)

OK

INSPECT COMBINATION METER
1. Check the A/T P indicator light.
  1. Disconnect the T5 switch connector.
  2. Turn the ignition switch ON.
  3. Connect the T5-1 terminal of the wire harness side connector to the body ground, and then check the A/T P indicator light.
    
    OK
    
    A/T P indicator light illuminates.
