detects a problem on any of those components, the PCM estimates where the
problem may be occurring, and will set a diagnostic trouble code. Diagnostic
trouble codes cover the auto-cruise control switch, stoplight switch and PCM. AUTO-CRUISE CONTROL SYSTEM DIAGNOSTIC TROUBLESHOOTING STRATEGY Use these steps to plan your diagnostic strategy. If you follow them carefully, you
will check most of the possible causes of an auto-cruise control system problem.
1. Gather information from the customer.
2. Verify that the condition described by the customer exists.
3. Check the vehicle for any auto-cruise control system DTC.
4. If you can verify the condition but no auto-cruise control system DTCs are set,
and the malfunction may be intermittent. Refer to HOW TO COPE WITH
INTERMITTENT MALFUNCTIONS
.
5. If you can verify the condition but there are no auto-cruise control system
DTCs, or the system cannot communicate with scan tool MB991958 (MUT-III
sub assembly), refer to SYMPTOM CHART
, and find the fault.
6. If there is an auto-cruise control system DTC, record the number of the code,
then erase the code from vehicle memory using the scan tool.
7. Re-create the auto-cruise control system DTC set conditions to see if the same
Auto-cruise Control System DTC will set again.
If the same Auto-cruise Control System DTC sets again, perform the
diagnostic procedures for the set code. Refer to DTC 15: AUTO

1. Connect scan tool MB991958 to the data link connec
tor.
NOTE: When special tool MB991824 is energized, special tool
MB991824 indicator light will be illuminated in a green
color.
NOTE: Disconnecting scan tool MB991958 is the reverse of the
connecting sequence, making sure that the ignition
switch is at the "LOCK" (OFF) position.
CAUTION: To prevent damage to scan tool MB991958, always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting scan tool
MB991958.
NOTE: If the battery voltage is low, diagnostic trouble codes will
not be set. Check the battery if scan tool MB991958 does
not display.

2. Turn the ignition switch to the "ON" position.
3. Depress the "CRUISE" (MAIN) switch to illuminate the "CRUISE" indicator
light in the combination meter.
4. Use scan tool MB991958 to read for auto-cruise control system diagnostic
trouble codes.
5. Turn the ignition switch to the "LOCK" (OFF) position and then back to "ON"
again.
6. Use scan tool MB991958 to erase for auto-cruise control system diagnostic
trouble codes.
7. Turn the ignition switch to the "LOCK" (OFF) position.
8. Disconnect scan tool MB991958.

CIRCUIT OPERATION This circuit judges the signals of each switch ("COAST/SET", "ACC/RES" and
"CANCEL") of the auto-cruise control switch. The PCM detects the state of the
auto-cruise control switch by sensing the voltages shown below.
When all switches are OFF: 4.7 - 5.3 volts When the "CRUISE" (MAIN) switch is "ON": 0 - 0.3 volts When the "COAST/SET" switch is ON: 2.1 - 2.7 volts When the "ACC/RES" switch is ON: 3.3 - 4.0 volts When the "CANCEL" switch is ON: 0.8 - 1.5 volts
DTC SET CONDITIONS Check condition
The CRUISE indicator light illuminates.
Judgement Criteria The "COAST/SET" or "ACC/RES" switch remains on for 60 seconds.
TROUBLESHOOTING HINTS (The most likely causes for this case:)
Malfunction of the auto-cruise control switch. Malfunction of the clock spring. Damaged harness or connector. Malfunction of the PCM.
DIAGNOSIS Required Special Tools:
MB991223: Harness Set MB991923: Power Plant ECU Check Harness MB991958: Scan Tool (MUT-III sub assembly)
MB991824: V.C.I.

2. Turn the ignition switch to the "ON" position.
3. Set scan tool MB991958 to read the diagnostic trouble codes.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Disconnect scan tool MB991958.
Q: Is DTC 15 set?
YES : Return to Step 1 .
NO : The procedure is complete.
DTC 21: Cancel Latch Signal System DTC SET CONDITIONS The PCM communicates cancellation retention information between the two
microprocessors. This DTC is set when cancellation retention information contains
inconsistency. TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:) Malfunction of the PCM. DIAGNOSIS Replace the PCM. [Refer to POWERTRAIN CONTROL MODULE (PCM)
].
Check that diagnostic trouble code 21 is not set.
