33/(F49) No. 24—No. 1
35/(F49) No. 23—No. 1
37/(F49) No. 31—No. 1
Is resistance 9.0±0.7Ω?
: Go to step8E7.
: Repair harness connector between ABSCM and
hydraulic unit.
8E7CHECK POOR CONTACT IN CONNEC-
TOR BETWEEN ABSCM AND HYDRAU-
LIC UNIT.
: Is there poor contact in connectors between
ABSCM and hydraulic unit?
: Repair connector.
: Go to step8E8.
8E8
CHECK ABSCM.
1) Connect all connectors.
2) Erase the memory.
3) Perform inspection mode.
4) Read out the trouble code.
: Is the same trouble code as in the current
diagnosis still being output?
: Replace ABSCM.
: Go to next.
: Are other trouble codes being output?
: Proceed with the diagnosis corresponding to the
trouble code.
: A temporary poor contact.
