MULTI-MODE MANUAL TRANSAXLE SYSTEM Multi-Mode Manual Transmission Warning Light Circuit
DESCRIPTION
The combination meter interprets the multi-mode manual transaxle system condition according to the information from the INDC and INDA circuits, and if necessary, illuminates (blinks) the multi-mode manual transaxle warning light and sounds the buzzer.
-
INDC Terminal Circuit:
The battery voltage is constantly supplied to the INDC circuit. If the INDC circuit is open, the combination meter detects a malfunction in the circuit and illuminates the multi-mode manual transaxle warning light. The INDC circuit is used to send the multi-mode manual transaxle warning light signal to the combination meter when the ignition switch is off.
-
INDA Terminal Circuit:
Power is supplied to the INDA circuit when the ignition switch is ON. While the ignition switch is ON, the combination meter controls the multi-mode manual transaxle warning light ON/OFF condition according to the signal from the INDA circuit. The INDA circuit is used to send the signal for multi-mode manual transaxle warning light and shift position indicator to the combination meter.
The contents of signals from the INDC and INDA circuits, and the status of the multi-mode manual transaxle warning light, buzzer and indicator are shown in the table below.
| INDA circuit state (at combination meter) | Normal | Inconsistent signal input (3 seconds or more) |
Interrupted signal input (3 seconds or more) |

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