Indicator Circuit

DESCRIPTION

If the stabilizer control ECU detects a malfunction in the KDSS, the KDSS indicator light comes on. At this time, the stabilizer control ECU records a DTC. Connect terminals TC and CG of the DLC3 to cause the KDSS indicator light to flash and a DTC to be output.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK KDSS INDICATOR LIGHT
(a) Confirm the KDSS indicator light condition.
Result:






B -- INSPECT FUSE
A -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (STABILIZER CONTROL ECU - COMBINATION METER ASSEMBLY)




(a) Disconnect the S36 connector from the stabilizer control ECU.
(b) Disconnect the C12 connector from the combination meter assembly.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (STABILIZER CONTROL ECU - COMBINATION METER ASSEMBLY)
OK -- REPLACE STABILIZER CONTROL ECU
3. INSPECT FUSE




(a) Remove the GAUGE fuse from the driver side J/B.
(b) Check for continuity of the GAUGE fuse.
Standard:
Continuity
NG -- INSPECT SHORT IN ALL COMPONENTS CONNECTED TO FUSE AND REPAIR OR REPLACE THEM IF NEEDED, AND REPLACE FUSE
OK -- Continue to next step.
4. INSPECT STABILIZER CONTROL ECU (KI TERMINAL)




(a) Disconnect the S36 connector from the stabilizer control ECU.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






OK -- REPLACE STABILIZER CONTROL ECU
NG -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (STABILIZER CONTROL ECU - COMBINATION METER ASSEMBLY)




(a) Disconnect the C12 connector from the combination meter assembly.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (STABILIZER CONTROL ECU - COMBINATION METER ASSEMBLY)
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - BATTERY)




(a) Disconnect the C9 connector from the combination meter assembly.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (COMBINATION METER ASSEMBLY - BATTERY)
OK -- REPLACE COMBINATION METER ASSEMBLY
