MULTI-MODE MANUAL TRANSAXLE SYSTEM Multi-Mode Manual Transmission Warning Light Circuit

DESCRIPTION

The combination meter interprets the multi-mode manual transmission system condition through the information from the INDC and INDA circuits, and if necessary, illuminates (blinks) the multi-mode manual transmission warning light.


The contents of signals from the INDC and INDA circuits, and the status of the multi-mode manual transmission warning light and indicator are shown in the table below.

When Ignition Switch ON:
INDA circuit state (at combination meter) Normal Inconsistent signal input (3 seconds or more) Interrupted signal input (3 seconds or more)
INDC circuit (at combination meter) Normal +B short or open Normal +B short or open Normal +B short or open

INSPECTION PROCEDURE

Tech Tips

Check that the multi-mode manual transmission warning light and shift position indicator come on.

Under normal condition, the shift position indicator indicates the current gear position while the ignition switch is ON, and the multi-mode manual transmission warning light comes on for bulb check for approximately 5 seconds when the ignition switch is turned from OFF to ON.

If the shift position indicator does not come on, the INDA circuit may be malfunctioning. If the multi-mode manual transmission warning light does not come on, the INDA and/or INDC circuits may be malfunctioning.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL ECU - COMBINATION METER)

    A01392LE01

    1. Disconnect the transmission control ECU connector.

    2. Disconnect the combination meter assembly connector.

    3. Check the resistance.

      Standard Resistance
      Tester Connections Specified Conditions
      INDC (A27-29) - BRQ (A22-4) Below 1 Ω
      INDA (A27-31) - TX+ (A22-5) Below 1 Ω
      INDC (A27-29) - Body ground 10 kΩ or higher
      INDA (A27-31) - Body ground 10 kΩ or higher
    4. Reconnect the transmission control ECU connector.

    5. Reconnect the combination meter assembly connector.


    NG
    OK
  2. INSPECT COMBINATION METER ASSEMBLY

    A0138IEE03

    1. Measure the voltage between the terminal of combination meter connector and the body ground.

      Standard Voltage
      Tester Connections Conditions Specified Conditions
      TX+ (A22-5) - Body ground Ignition switch OFF Approximately 3.64 V
      TX+ (A22-5) - Body ground Ignition switch ON Approximately 1.44 V
      BRQ (A22-4) - Body ground Always Approximately 1.44 V
