Code No.56: N range lamp system
OPERATION
If a fail-safe operation is activated during driving, the
engine-A/T-ECU flashes the N range lamp at a
frequency of 1 Hz to inform the driver.
diagnosis code set conditions
If the N range signal is OFF after the N range lamp
illuminates (ON), it is judged that there is a
short-circuit to earth or open circuit in the N range
lamp, and code No. 56 is output.
Possible causes
•
Malfunction of the combination meter
•
Damaged harness wires and connectors
•
Malfunction of the engine-A/T-ECU
DIAGNOSIS
STEP 1. MUT-II/III diagnosis code.
Either of diagnosis codes 27 or 28 is set, inhibtor
switch is defective.
Q: Are diagnosis codes 27 or 28 output?
YES <diagnosis code 27 is set> :
Refer to
diagnosis code 27: Inhibitor switch system
YES <diagnosis code 28 is set> :
Refer to
diagnosis code 28: Inhibitor switch system
NO :
Go to Step 2.
STEP 2. Check the N range lamp.
(1) Turn the ignition switch to the ON position.
(2) Shift the selector lever to the N position.
Q: Does the N range lamp illuminate?
YES :
Go to Step 10.
NO :
Go to Step 3.
STEP 3. Check the N range lamp valve.
(1) Remove the combination meter. (Refer to

STEP 6. Check the harness between combination
meter connector C-05 terminal No.12 and body
earth.
Check the earth line for open circuit or short-circuit.
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Repair the wiring harness.
STEP 7. Measure the voltage at combination
meter connector C-05.
(1) Disconnect the connector, and measure the
voltage between terminal 2 and earth at the
wiring harness side.
(2) Turn the ignition switch to the ON position.
(3) Shift the selector lever to the N position.
OK: System voltage
Q: Is the check result normal?
YES :
Check the combination meter, and replace if
necessary.
