REQUESTING FAULT CODES MODE
1. While in "requesting number of fault codes" mode, push rear
sonar system OFF switch once.
2. The sonar buzzer will sound once.
3. Rear sonar system OFF indicator will flash and sonar buzzer will sound the first digit of the fault code followed by a one second
pause.
4. Rear sonar system OFF indicator will flash and sonar buzzer will sound the second digit of the fault code followed by a four sec-
ond pause.
5. The fault codes will repeat five times then pause. NOTE:
Requesting fault codes will exit unless the fault code is acknowledged before five repeats ends.
The fault code is acknowledged by pushing the rear sonar system OFF switch once (the sonar buzzer
may sound). When all fault codes have been indicated, idle mode will be entered. See the following table
for fault code identification.
IDLING OR CLEARING FAULT CODES MODE
NOTE:
While in idle mode, self-diagnosis will automatically exit if no activity occurs for thirty seconds.
1. Push and hold rear sonar system OFF switch for three secondsto reset time-out counter.
2. Push and hold rear sonar system OFF switch for three seconds to clear codes.

When the rear sonar system OFF switch is OFF, the indicator
lamp does not light and the buzzer does not sound. 1. Check rear sonar system OFF switch for malfunction. Refer to
DI-70, "
REAR SONAR SYSTEM OFF SWITCH" .
2. Check rear sonar system OFF switch ground circuit.
3. Check harness and connections between rear sonar system OFF switch and sonar control unit.
4. Replace sonar control unit. Refer to DI-70, "
SONAR CON-
TROL UNIT" .
When the rear sonar system OFF switch is OFF, the indicator
lamp does not light but buzzer sounds. 1. Check rear sonar system OFF indicator for malfunction. Refer
to DI-70, "
REAR SONAR SYSTEM OFF INDICATOR" .
2. Check harness and connections between rear sonar system OFF indicator and sonar control unit.
3. Replace sonar control unit. Refer to DI-70, "
SONAR CON-
TROL UNIT" .
When the rear sonar system OFF switch is OFF, the sonar
buzzer does not sound but indicator lamp illuminates. 1. Check sonar buzzer. Refer to
DI-70, "
SONAR BUZZER" .
2. Check harness and connections between sonar buzzer and sonar control unit.
3. Replace sonar control unit. Refer to: DI-70, "
SONAR CON-
TROL UNIT" .
When rear sonar system OFF switch is ON, the rear sonar sys-
tem OFF indicator lamp lights up and the sonar buzzer sounds
intermittently (for about 4 seconds). 1. Check harness between rear sonar sensors and sonar control
unit for an open condition.
2. Check rear sonar sensors for malfunction.
3. Replace sonar control unit. Refer to DI-70, "
SONAR CON-
TROL UNIT" .
The rear sonar system operates with the rear sonar system OFF
switch OFF. 1. Check rear sonar system OFF switch for malfunction. Refer to
DI-70, "
REAR SONAR SYSTEM OFF SWITCH" .
2. Check rear sonar system OFF switch ground circuit.
3. Check harness and connections between rear sonar system OFF switch and sonar control unit.
4. Replace sonar control unit. Refer to DI-70, "
SONAR CON-
TROL UNIT" .
When the transmission gear selector lever is in the R position
and the rear sonar system OFF switch is OFF, the sonar system
does not operate. 1. Check for PNP switch failure. Refer to
AT-86, "
SELF-DIAG-
NOSTIC RESULT MODE" .
2. Check harness and connections between sonar control unit and PNP/reverse lamp circuits.
3. Replace sonar control unit. Refer to DI-70, "
SONAR CON-
TROL UNIT" .
When the rear sonar system OFF switch is OFF, the indicator
lamp lights up and buzzer sounds although there is no obstacle
within the detection range. 1. Check for adhesion of snow, mud, or other foreign objects to
rear sonar sensors; dew condensation; etc. Refer to DI-66,
"Pre-diagnosis Inspection" .
2. Check that the rear sonar sensor is properly aligned (bumper is not misaligned, no deformation in sensor mounting area
3. Check harness and connections between rear sonar sensors and sonar control unit.
4. Check rear sonar sensors for malfunction.
5. Replace sonar control unit. Refer to DI-70, "
SONAR CON-
TROL UNIT" .
The rear sonar sensors do not operate according to the distance
between each sensor and the obstacle. (There is a large error in
the obstacle detection distance. 1. Check rear sonar sensors for malfunction.
2. Replace sonar control unit. Refer to
DI-70, "
SONAR CON-
TROL UNIT" .
3. Check for adhesion of snow, mud, or other foreign objects to rear sonar sensors; dew condensation; etc. Refer to DI-66,
"Pre-diagnosis Inspection" .
4. Check that the rear sonar sensor is properly aligned (bumper is not misaligned, no deformation in sensor mounting area
