I found a B1008 in the speedo section of the manual.
Trip Odometer Reset Switch Closed
Diagnostic Trouble Code (DTC) B1008 will be set if trip odometer
reset switch terminals are in a constant shorted state.
Clear codes using speedometer self diagnostics.
See Section 4.6 SPEEDOMETER SELF DIAGNOSTICS.
Confirm proper operation with no check engine lamp.
GENERAL
The speedometer is capable of displaying and clearing
speedometer, tachometer, TSM/TSSM/HFSM, ABS and ECM
Diagnostic Trouble Codes (DTCs) (diagnostic mode).
DIAGNOSTICS
Diagnostic Tips
• For a quick check of speedometer function, a "WOW" test
can be performed. Press and hold trip odometer reset
switch then turn Ignition Switch to IGNITION. Background
lighting should illuminate, speedometer needle should
sweep its full range of motion, and indicator lamps (sixth
gear, check engine, low fuel, battery, security, cruise
enabled, pursuit, and ABS) should illuminate. Some lamps,
like the cruise enabled lamp, may illuminate even if the
vehicle is not equipped with cruise control. See Figure 4-8.
• If speedometer fails "WOW" test, check for battery, ground,
ignition, trip odometer reset switch and accessory wiring
to speedometer. If any feature in the speedometer is nonfunctional,
see 2.2 INITIAL DIAGNOSTIC CHECK:
SPEEDOMETER.
Diagnostic Notes
Each reference number below correlates to a circled number
on the flow chart(s).
1. To exit diagnostic mode, turn Ignition Switch OFF.
2. To clear DTCs for the selected module:
a. Press and hold the trip odometer reset switch for more
than 5 seconds to display available modules, release.
b. Press the trip odometer reset switch to choose
module.
c. Press and hold the trip odometer reset switch for more
than 5 seconds to display the DTC, release.
d. Press and hold the trip odometer reset switch for more
than 5 seconds to clear DTC(s) for the module
selected.
Codes and procedure are available here...
