ELECTRICAL / GARAGE SHIFT
TEST
This preliminary test should be performed before a hoist or
road test to make sure electronic control inputs are con-
nected and operating. If the inputs are not checked before
operating the transmission, a simple electrical condition
could be misdiagnosed as a major transmission condition.
A scan tool provides valuable information and must be used
on the automatic transmission for accurate diagnosis.
1. Move gear shift control lever to P (Park) and set the
parking brake.
2. Connect scan tool to Data Link Connector (DLC)
terminal.
3. Start engine.
4. Turn the scan tool ON.
5. Verify that the appropriate signals are present. These
signals may include:
• ENGINE SPEED
• VEHICLE SPEED
• THROTTLE POSITION
• ACCEL. PEDAL POSITION
• TRANSMISSION GEAR STATE
• GEAR SHIFT LEVER POSITION
• TRANSMISSION FLUID TEMPERATURE
• CLOSED THROTTLE POSITION LEARN
• OPEN THROTTLE POSITION LEARNT
• CLOSED ACCEL. PEDAL POSITION LEARNT
• OPEN ACCEL. PEDAL POSITION LEARNT
• A/C COMPRESSOR STATUS
• KICKDOWN SWITCH STATUS
• 4WD STATUS
• MODE SWITCH
• THROTTLE POSITION VOLTAGE
• GEAR SHIFT LEVER POSITION VOLTAGE
• TRANS. FLUID TEMPERATURE VOLTAGE
• A/C SWITCH
• KICKDOWN SWITCH VOLTAGE
• 4WD LAMP LOW VOLTAGE
• 4WD LAMP HIGH VOLTAGE
• MODE SWITCH VOLTAGE
• BATTERY VOLTAGE
6. Monitor the A/C COMPRESSOR STATUS signal while
pushing the A/C switch.
• The A/C COMPRESSOR STATUS should come ON
when the A/C switch is pressed, and turn OFF when
the A/C switch is repushed.

7. Monitor the GEAR SHIFT LEVER POSITION signal
and move the gear shift control lever through all the
ranges.
• Verify that the GEAR SHIFT LEVER POSITION
value matches the gear range indicated on the
instrument panel or console.
• Gear selections should be immediate and not
harsh.
8. Move gear shift control lever to neutral and monitor
the THROTTLE POSITION signal while increasing and
decreasing engine speed with the accelerator pedal.
• THROTTLE POSITION should increase with
engine speed.
ROAD TEST PROCEDURE
• Perform the road test using a scan tool.
• This test should be performed when traffic and road
conditions permit.
• Observe all traffic regulations.
ELECTRONIC ADJUSTMENTS
Idle speed adjustments
Carry out the adjustments to the idle speed as detailed in
the workshop manual.
Vehicle coding
The vehicle coding is integrated as part of the diagnostic
software. A scan tool has the function to code the ve-hicle
through the K-line.
Throttle clearing
The leant throttle clearing routine uses the mode switch
and gear lever. Carry out the following steps to complete
the automated throttle clearing procedure:
1. Switch ignition "ON" with handbrake applied and
engine "OFF".
2. Select the selector lever to 1st gear and "WINTER"
mode.
3. Move the selector lever to 2nd gear and "ECONO" or
"POWER" mode.
4. Move the selector lever to 3rd gear and "WINTER"
mode.
