### ELECTRONIC CONTROLLED AUTOMATIC TRANSMISSION SYSTEM > A/T P Indicator Circuit

## for Preparation Click here

## 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

1.INSPECT PARK/NEUTRAL POSITION SWITCH

1. Disconnect the N1 PNP switch connector.

1. Measure the resistance of the PNP 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 |

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

1. Remove the transfer indicator switch.

1. 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 |

3.INSPECT COMBINATION METER

1. Check the A/T P indicator light.

   1. Disconnect the T5 transfer indicator 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.

| NG |

REPLACE COMBINATION METER

OK |
