DTC 96

Torque Converter Circuit And Flow:

CIRCUIT DESCRIPTION
The torque converter clutch (TCC) is a hydraulic coupler, which transfers torque from the engine to the transaxle. The converter passes fluid from the converter pump assembly, through a turbine assembly and then through the stator assembly this method enables the torque converter to multiply torque and move the vehicle. This process will develop heat, which will be transferred to the transaxle fluid to be cooled.

DTC 96 WILL SET WHEN
- No DTCs 21, 22 and 24.
- Brakes applied.
- Vehicle speed less than 5 mph.
- Throttle angle greater than 65 degrees for 12 seconds.

ACTION TAKEN (PCM WILL DEFAULT TO)
With a current DTC 96 set, the PCM will illuminate the Malfunction Indicator Lamp (MIL) (Service Engine Soon).

DTC 96 WILL CLEAR WHEN
The fault no longer exists.

DIAGNOSTIC AIDS
This test checks for an unusually large throttle angle at low vehicle speed with the brake being applied. The primary purpose of the DTC is to record snapshot data and alert driver of the dangerous driving practices.

NOTE: Most occurrences of this DTC will be due to the application of the brake and accelerator at the same time.

TCC Brake Switch, Transaxle Range Switch, Vehicle Speed Sensor and Throttle Position (TP) sensor failures should be caught by other diagnostic trouble codes. if any of the checks below fail, see the indicated DTC chart for diagnosis.
- Check operation of brake switch by using TCC brake switch input test (refer to DTC 90).
- Check operation of TP sensor by monitoring TP sensor degrees while moving throttle (refer to DTC 21, 22 and 70).
- Check for correct mph indication on instrument panel (refer TO DTC 24).
- Check operation of Transaxle Range Switch by monitoring Tech 1 display while shifting through the ranges (refer to DTC 91).
