DTC P0821 Gear Lever "X" Position Circuit


DESCRIPTION

Based on the signal from the transmission shift main switch, the TCM detects whether the shift lever position is in the E or M position. If the shift lever position switch is ON despite the shift lever position being N or R, the TCM sets the DTC.
For more details of the transmission shift main switch, refer to DTC P0820 (See page Нажмите здесь).

DTC No.
DTC Detection Condition
Trouble Area
P0821
The TCM detects the following conditions simultaneously:
(1-trip detection logic)
  1. Shift lever position is in N or R
  2. MSDW signal is ON for 1.0 second
  1. Transmission shift main switch (built into shift lever assembly)
  2. Short in MDSW signal circuit
  3. TCM

INSPECTION PROCEDURE

1.INSPECT SHIFT LOCK CONTROL UNIT ASSEMBLY


    COROLLA, AURIS. ZZE150 ZRE151,152 NDE150.Механическая Трансмиссия 'Multimode' C53A.Система Механической Трансмиссии

  1. Disconnect the shift lock control unit connector.

  1. Check the resistance when changing the shift lever position.

    Standard resistance:
    Tester Connection
    		Shift Lever Position
    		Specified Condition
    E31-4 (MDSW) - E31-8 (GND)
    		R, N or E
    		10 kΩ or higher
    E31-4 (MDSW) - E31-8 (GND)
    		M, + or -
    		Below 1 Ω

  1. Reconnect the shift lock control unit connector.

2.CHECK HARNESS AND CONNECTOR (SHIFT LOCK CONTROL UNIT - TCM)


    COROLLA, AURIS. ZZE150 ZRE151,152 NDE150.Механическая Трансмиссия 'Multimode' C53A.Система Механической Трансмиссии

  1. Disconnect the shift lock control unit connector.

  1. Disconnect the TCM connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    E33-10 (MDSW) - E31-4 (MDSW)
    		Always
    		Below 1 Ω
    E33-10 (MDSW) - Body ground
    		↑
    		10 kΩ or higher

  1. Reconnect the shift lock control unit connector.

  1. Reconnect the TCM connector.
