< COMPONENT DIAGNOSIS >
DTC 90 STOP LAMP RLY FIX
1. Connect connectors of ICC unit and stop lamp switch.
2. While performing active test (STOP LAMP: STP LMP DRIVEON) with CONSULT-III, chec k voltage between ICC unit harness
connector B17 terminal 47 and ground.
Does battery voltage exist?
YES >> GO TO 14
NO >> Replace ICC unit. Refer to CCS-71, "
ICC Unit". Erase
DTC and perform ICC system running test. Refer to
CCS-8, "
ACTION TEST : ICC System Running Test".
14.CHECK ICC BRAKE HOLD RELAY POWER SUPPLY CIRCUIT
Check voltage between ICC brake hold relay harness connector
E134 terminal 7 and ground.
Does battery voltage exist?
YES >> GO TO 15
NO >> • Check fuse or ICC brake hold relay power supply har- ness.
• Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC System Run-
ning Test".
15.CHECK HARNESS BETWEEN ICC BRA KE HOLD RELAY AND ICC UNIT
1. Turn ignition switch OFF.
2. Disconnect ICC unit harness connectors.
3. Check continuity between ICC brake hold relay harness connec- tor (B) E134 terminal 6 and ICC unit harness connector (A) B17
terminal 38.
4. Check continuity between ICC unit harness connector (A) B17 terminal 38 and ground.
Are continuity test results as specified?
YES >> GO TO 16
NO >> • Repair harness between ICC brake hold relay and ICC unit or between ICC brake hold relay and stop lamp switch.
• Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test".
16.CHECK ICC BRAKE HOLD RELAY
1. Connect ICC unit and ICC brake hold relay harness connectors.
2. Disconnect stop lamp switch connector.
3. Perform active test (STOP LAMP) with CONSULT- III, and make sure that stop lamps are illuminated.
Do the stop lamps illuminate?
YES >> GO TO 17
NO >> Replace ICC brake hold relay. Erase DTC and perform ICC system running test. Refer to CCS-8,
"ACTION TEST : ICC System Running Test".
17.CHECK ICC UNIT STANDARD VOLTAGE 47 - Ground
Battery voltage should exist
(during active test)
SKIA3075E
7 - Ground Battery voltage should exist
ALOIA0010ZZ
6 - 38 Continuity should exist.
38 - Ground Continuity should not exist.
