Repair Information
12
Diff. Lock Solenoid
Shorted to Ground or
Open Circuit
Verify no continuity between the Diff Lock Solenoid and ground. Check for corroded/
damaged wiring or connectors between the ECU and Diff Lock Solenoid.
13
Diff. Lock Solenoid
Shorted to Voltage
Verify no continuity between the Diff Lock Solenoid and voltage. Check for corroded/
damaged wiring or connectors between the ECU and Diff Lock Solenoid. Issue a "Clear
DTC" command to exit Dynamometer Test Mode.
14
Sensor CAN Supply
Voltage Error
Incorrect supply voltage for the SAS-60 and the Yaw Rate sensor. Verify proper voltage
at sensor connectors. Verify wiring between the ECU and the sensors. Verify proper
output voltage from ECU. Note: When checking for voltage at YAW/LAS & SAS, the
voltage will only be present momentarily at key ON.
15-21
Reserved
22
ESP Sensor Voltage
Out of Range
Incorrect supply voltage for the SAS-60 and the Yaw Rate sensor. Verify proper voltage at
sensor connectors. Verify wiring between the ECU and the sensors. Verify proper output
voltage from ECU. Note: When checking for voltage at YAW/LAS & SAS, the voltage will
only be present momentarily at key ON.
23
Short to Voltage
I/O 2 or I/O 3 Shorted to Voltage. (A good location to check first, is the ECU Stop Lamp
Relay wiring output X3-8.)
24
HSA Solenoid Shorted
to Voltage
Verify no continuity between the HSA Solenoid and voltage. Check for corroded/damaged
wiring or connectors between the ECU and HSA solenoid.
25
HSA Solenoid Open or
Shorted to Ground
HSA solenoid is shorted to ground or has a broken wire. Verify no continuity between the
HSA solenoid and ground. Check for corroded/damaged wiring or connectors between
the ECU and the HSA solenoid.
26
HSA Solenoid Shorted
to Voltage
Verify no continuity between the HSA Solenoid and voltage. Check for corroded/damaged
wiring or connectors between the ECU and HSA Solenoid.
27
Brake Lamp
Brake lamp input mismatch with brake lamp output
