Has a problem been found?
YES
a.
Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
a.
Go to " RLSS Signal Inspection " procedure.
Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration,or damage.
Has a problem been found?
YES
Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
Go to " RLSS Signal Inspection " procedure.
Engine : ON.
TCCU connector : Connect.
Monitor signal waveform between terminal 8 of TCCU harness connector C258 and chassis ground .
Start and drive vehicle in gear and maintain vehicle speed at approx. 10km/h or less(6mph or less)
Specification : Signal Waveform & Data
The above value is only for reference. The actual value may differ from it according to various engine condition.
Is RLSS Signal display near the specified value?
YES
Fault is intermittent caused by poor contact in the sensor’s and/or TCCU’s connector or was repaired and TCCU memory was not cleared.Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
Go to " RLSS input circuit ground short inspection " procedure.
Ignition "OFF".
TCCU, RLSS connector : Disconnect.
Measure resistance between terminal 8 of TCCU harness connector C258 and chassis ground .
Specification : Approx. ∞ Ω
The above value is only for reference. The actual value may differ from it according to various engine condition.
Is resistance display near the specified value?
YES
Go to " RLSS input circuit line open inspection " procedure.
NO
Check for ground to short circuit of RLSS circuit.
Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
Ignition OFF
TCCU, RLSS connector : Disconnect.
Measure resistance between terminal 8 of TCCU harness connector C258 and terminal 1 of FRSS harness connector F28 .
Specification : Approx. 1Ω below.
The above value is only for reference. The actual value may differ from it according to various engine condition.
Is resistance display near the specified value?
YES
Go to " RLSS ground open inspection " procedure.
NO
Check for open circuit of RLSS circuit.
Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
Ignition OFF
TCCU, RLSS connector : Disconnect.
Measure resistance between terminal 19 of TCCU harness connector M79 and terminal 2 of RLSS harness connector M65 .
Specification : Approx. 1Ω below.
The above value is just for reference. The actual value may differ from it according to various engine condition.
Is resistance display near the specified value?
YES
Go to "Component inspection" procedure.
NO
RLSS ground circuit open checking.
Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
