DTC P0734

- 4th Gear Ratio Incorrect

Diagnostic Fault Information

Circuit/System Description

The shift control solenoid assembly (SLC1, SLC2, SLC3, SLB1) and the line pressure control solenoid (SLT) are installed on the front valve body.

The solenoids linearly control hydraulic pressure in response to signals output from the transmission control module (TCM). SLC1, SLC2, SLC3,

SLB1 controls hydraulic pressure to the clutches (C1, C2, C3) and brake (B1) for smooth shifting. According to each shift control solenoid

assembly, the transmission shifts from 1st gear into 6th gear and vice versa. As a fail-safe function, if any shift control solenoid assembly

abnormality occurs, the TCM will disable the current to the solenoids.

Conditions for Running the DTC

* The ignition voltage is 10.2-15.5 V.

* The engine speed is greater than 400 RPM for 2 s.

* The transmission is not in emergency mode.

* TCM communication is normal.

* Transmission fluid temperature is higher than 20掳C (68掳F).

* DTCs P0716. P0717, P0721 and P0722 are not set.

Conditions for Setting the DTC

* Driving in D range, 4th gear.

DTC P0963

- Line Pressure Control (PC) Solenoid Control Circuit High Voltage

Diagnostic Fault Information

Circuit/System Description

The line pressure control (PC) solenoid is part of the control solenoid valve assembly which has no serviceable components. The normally high line

PC solenoid regulates and directs the PC solenoid oil pressure to the pressure regulator valve and isolator valve. Increasing line PC solenoid

pressure increases transmission line pressure. The transmission control module (TCM) varies the current to the line PC solenoid through a low side

driver. Decreasing the current to the line PC solenoid increases line PC solenoid oil pressure by closing OFF the solenoid exhaust port. Increasing

the current to the line PC solenoid decreases line PC oil pressure by opening the solenoid exhaust port. Line PC solenoid power is supplied by the

TCM through a high side driver (HSD). The HSD protects the circuit and components from excessive current flow. If excessive current flow is

detected, the HSD will turn OFF. When the fault is corrected the HSD will reset.

Conditions for Running the DTC

* The engine speed is greater than 400 RPM for 5 seconds.

* The ignition voltage is 8.6 volts or greater.

Conditions for Setting the DTC

P0961

The TCM detects an internal electrical malfunction of the line PC solenoid where the measured line PC solenoid current does not equal the

commanded line PC solenoid current for 5 seconds.

P0962

The TCM detects a short to ground or an open/high resistance on the line PC solenoid control circuit for 1 second.

P0963

The TCM detects an open or a short to voltage on the line PC solenoid control circuit for 1 second.

- Clutch Pressure Control (PC) Solenoid 3 - Stuck On

Circuit/System Description

The clutch pressure control (PC) solenoid 3 is part of the control solenoid valve assembly, which has no serviceable components. The PC solenoid

3 regulates transmission fluid pressure (TFP) to the R1/4-5-6 clutch regulator valve which controls pressure to the low and reverse clutch and the

4-5-6 clutch. The transmission control module (TCM) calculates gear ratio based on the RPM signals from the input speed sensor (ISS) and the

output speed sensor (OSS). The TCM compares the expected transmission gear ratio to the calculated gear ratio for each commanded gear.

DTC B1024 11

- Circuit Board Temperature Sensor Above Maximum Threshold

Circuit/System Description

The audio amplifier monitors the internal circuitry for excessive temperature. When the amplifier senses an internal circuitry temperature greater

than 95掳C (203掳F), the amplifier will set DTC B1024 11 and shut down until the internal circuitry cools below 90掳C (194掳F).

Conditions for Running the DTC

* Radio ON.

* Battery voltage must be between 9-16 volts.

Conditions for Setting the DTC

The audio amplifier detects an over-heat condition greater than 95掳C (203掳F) of the internal amplifier circuitry.

Action Taken When the DTC Sets

The audio amplifier will shut down and all speakers will be inoperative.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists.

* A history DTC will clear once 100 consecutive malfunction-free ignition cycles have occurred.

Diagnostic Aids

Extended use or extremely high volume especially in warm weather conditions may cause this DTC to set. Under these conditions it may be normal

for this DTC to set to prevent permanent damage to the audio amplifier circuitry.
