SELF-DIAGNOSTIC SYSTEM
SYSTEM DIAGNOSIS
NOTE: Before testing transmission, ensure fluid level is correct
and throttle and shift cables are properly adjusted. Ensure
engine starts with shift lever in Park and Neutral to ensure
proper adjustment of park/neutral position switch.
Transmission must first be tested by checking for stored
codes. See RETRIEVING DIAGNOSTIC TROUBLE CODES (DTC).
TCM monitors transmission operation and contains a self-
diagnostic system which stores a DTC if an electronic control system
failure or problem exists. If a problem exists in any of the solenoids
or speed sensors and a DTC is set, TCM delivers a signal to blink the
ATF TEMP light on instrument panel to warn the driver. DTC may be set
if a failure exists and can be retrieved for transmission diagnosis.
RETRIEVING DIAGNOSTIC TROUBLE CODES (DTC)
NOTE: Before retrieving DTC, ensure proper battery voltage exists
for proper self-diagnosis system operation. DO NOT disconnect
battery or ECM connectors before retrieving DTC.
Retrieving Codes Using Scan Tool
Ensure ignition switch is in OFF position. Connect scan tool
to Data Link Connector (DLC). See Fig. 5. Turn ignition switch to ON
position. Check for stored DTC and record code(s). See DIAGNOSTIC
TROUBLE CODE IDENTIFICATION table.
Page 160 of 1501
Once repairs have been performed, DTCs must be cleared from
TCM memory. DTCs may be cleared by disconnecting negative battery
cable for 10 seconds or more. Reconnect cable and ensure DTCs have
been cleared. Start engine and warm to normal operating temperature.
Run engine at idle for 10 minutes. DTCs may also be cleared using scan
tool. Refer to manufacturer's instruction manual.
DIAGNOSTIC TESTS
NOTE: For terminal and wire color identification, see WIRING
DIAGRAMS.
DTC 11: THROTTLE POSITION (TP) SENSOR
For diagnosis and testing information, see appropriate SELF-
DIAGNOSTICS article in ENGINE PERFORMANCE section. If TP sensor is
okay, check wiring harness and connectors between TP sensor and TCM.
Repair if necessary. If wiring harness and connectors are okay,
replace TCM.
DTC 15 & 16: OPEN OR SHORT IN OIL TEMPERATURE SENSOR CIRCUIT
1) Test oil temperature for proper operation. See OIL
TEMPERATURE SENSOR under COMPONENT TESTING. If oil temperature sensor
is okay, check wire harness, connectors and ground circuit for poor
connections or damage. Go to next step.
2) If wire harness and connectors are okay, check DTCs again
and verify code No. 15 or No. 16 still exists. If either code still
exists, replace TCM.
DTC 21 & 22: SHORT OR OPEN IN IGNITION SIGNAL CIRCUIT
1) Using an external tachometer, verify vehicles' tachometer
is operating accurately. If tachometer is incorrect, check ignition
coil and ignition power transistor and circuits for malfunction. See
appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE section.
2) If tachometer is okay, check TCM wire harness connector
for poor connection. If wire harness is okay, recheck DTCs. If codes
reappear check wire harness between ignition power transistor and TCM.
If wire harness is okay, replace TCM.
DTC 23 & 24: OPEN OR SHORT IN SIGNAL LINE (ECT) FROM ECM TO
TCM
Check wire harness, connectors and ground circuit for poor
connections or damage. Go to next step. If wire harness and connectors
are okay, check DTCs again and verify code No. 23 or No. 24 still
exists. If either code still exists, replace TCM.
