6C-22 Power Assisted Steering System:
DTC Troubleshooting
Step
1 Was "EPS System Check" performed?
2 DTC check
Is DTC C1113, C1114 and/or DTC C1119 indicated together?
3 Torque sensor internal failure signal circuit check
1) Check for P/S control module connector ("E52") for
proper connection.
2) With ignition switch turned OFF, disconnect torque
sensor connector.
3) Check for voltage between "E53-1" ("YEL" wire) terminal
and body ground with ignition switch ON.
Is it about 5 V?
4 Torque sensor internal failure signal circuit check
1) With ignition switch turned OFF, connect torque sensor
connector.
2) Check that voltage between "E52-16" ("YEL" wire)
terminal and body ground is about 5V at the moment of
ignition switch turned ON.
Is it about 5 V?
5 Torque sensor internal failure signal circuit wire check
1) Disconnect P/S control module.
2) Check that torque sensor failure signal circuit is as
follows.
• Insulation resistance of wire harness is infinity
between "Torque sensor internal failure signal circuit"
terminal and other terminal at torque sensor
connector.
• Insulation resistance between "Torque sensor internal
failure signal circuit" and vehicle body ground is
infinity.
Is circuit in good condition?
